'''Кичмењаци''' ([[Латински језик|лат.]] -{Vertebrata}-) билатерално су симетрични [[хордати]] са развијеном [[лобања|лобањском чауром]] у којој се налази [[мозак]]. Највећи број кичмењака поседује [[кичмени пршљен|кичмене пршљенове]] и сегментисано тело. Кичменица се састоји од кичмених пршљенова. Са леђне стране пршљенова постоје наставци који обухватају задњи део нервне цеви — кичмену мождину и тако је штите.

Кичмењаци су подељени на [[рибе]], [[Водоземци|водоземце]], [[Гмизавци|гмизавце]], [[Сисари|сисаре]] и [[птице]]. Екстантне кичмене опције величине су од врсте [[жаба]] -{''Paedophryne amauensis''}-, са само 7,7{{nbsp}}mm до [[Plavi kit|плавог кита]], до 33{{nbsp}}m. Кичмењаци чине мање од пет процената свих описаних животињских врста; остали су [[бескичмењаци]], који немају [[Кичма|кичму]].

Кичмењачи традиционално укључују [[слепуље]], које немају одговарајуће пршљенове услед губитка у еволуцији,<ref>{{Cite journal|last=Ota|first=Kinya G.|last2=Fujimoto|first2=Satoko|last3=Oisi|first3=Yasuhiro|last4=Kuratani|first4=Shigeru|date=25. 1. 2017|title=Identification of vertebra-like elements and their possible differentiation from sclerotomes in the hagfish|journal=Nature Communications|volume=2 |doi=10.1038/ncomms1355 |issn=2041-1723 |pmc=3157150|pmid=21712821|pages=373}}</ref> иако њихови најближи живи рођаци, пакларе, раде.<ref name="hagfish">{{cite journal|title=Monophyly of Lampreys and Hagfishes Supported by Nuclear DNA–Coded Genes |url=https://archive.org/details/sim_journal-of-molecular-evolution_1999-12_49_6/page/729 | author = Kuraku |date=децембар 1999|journal=Journal of Molecular Evolution | volume = 49 |doi=10.1007/PL00006595 |pmid=10594174|last2=Hoshiyama|first2=D |last3=Katoh|first3=K |last4=Suga|first4=H |last5=Miyata|first5=T |issue=6|displayauthors=1 |pages=729–35}}</ref> Међутим, [[Слепуље|слепуља]] поседује лобању. Из тог разлога, -{''subphylum''}- се понекад назива -{''Craniata''}- када се говори о [[Морфологија (биологија)|морфологији]].

== Етимологија ==
Порекло кичмењака произашло је из [[Латински језик|латинске]] речи -{''Vertebratus''}-, што значи ''спој кичме''.<ref>{{cite web|title=vertebrate |publisher=Dictionary.com. |work=Online Etymology Dictionary | author = |url=http://dictionary.reference.com/browse/vertebrate|accessdate=14. 4. 2018}}</ref> Прото-индоевропско порекло [[језик]]а још увијек није јасно.

''Вретенчар'' је изведен из речи вретенца, који се односи на било коју од [[кост]]ију или сегменте [[Кичмена колона|кичмене колоне]].<ref>{{cite web|title=vertebra |publisher=Dictionary.com. |work=Online Etymology Dictionary | author = |url=http://dictionary.reference.com/browse/vertebra|accessdate=14. 4. 2018}}</ref>

== Анатомија и морфологија ==
Сви кичмењаци изграђују се по основном делу тела [[Хордати|хордата]]: круту [[кост]] која пролази кроз животињу ([[Кичма|кичмени стуб]] и / или -{''notochord''}-),<ref>{{cite web|last=Waggoner|first=Ben|title=Vertebrates: More on Morphology|url=http://www.ucmp.berkeley.edu/vertebrates/vertmm.html|publisher=UCMP|accessdate=14. 4. 2018}}</ref> са шупљом цевчицом нервног ткива (кичмене мождине) а испод њега се налази [[Crevo (zoologija)|црево]].

На свим кичмењацима, уста се налазе на доњем предњем делу [[животиња|животиње]], док се [[анус]] налази при крају тела. Преостали део тела који се наставља након ануса, формира [[реп]] са пршљенима и кичменом мождином, али без црева.<ref name="Romer">Romer, A.S. (1949): ''The Vertebrate Body.'' W.B.

=== Први кичмењаци ===
[[Датотека:Haikouichthys cropped.jpg|250п|десно|мини|Један од првих кичмењака -{''[[Haikouichthys]]''}-]]

Сматра се да су кичмењаци настали пре око 525 милиона година током експлозије у Камбрију, у којима је дошло до порасти разноврсности организама. Први изумрли најпознатији кичмењак је био -{''[[Myllokunmingia]]''}-.<ref name="Shu  1999">{{cite journal|title=Lower Cambrian vertebrates from south China |url=https://archive.org/details/sim_nature-uk_1999-11-04_402_6757/page/42 | author = Shu |date=4. 11. 1999|journal=Nature| volume=402|doi= 10.1038/46965|last2=Luo|first2=H-L.|last3=Conway Morris|first3=S.|last4=Zhang|first4=X-L.|last5=Hu|first5=S-X. |last6=Chen |first6=L. |last7=Han |first7=J. |last8=Zhu |first8=M. |last9=Li |first9=Y. |issue=6757 |bibcode=1999Natur.402...42S |first10=L-Z.|displayauthors=1 |last10=Chen |pages=42–46}}</ref>

Још један рани кичмењак је -{''[[Haikouichthys]]''}-. За разлику од друге фауне која је доминирала Камбријанцима, ове групе су имале основни стадијум кичменог тела: нотохорду, рудиментарне пршљенове и добро дефинисану [[глава|главу]] и [[реп]].<ref>{{cite web|last=Waggoner|first=B.|title=Vertebrates: Fossil Record|url=http://www.ucmp.berkeley.edu/vertebrates/vertfr.html|publisher=UCMP|accessdate=15. 7. 2011|archive-url=https://web.archive.org/web/20110629070158/http://www.ucmp.berkeley.edu/vertebrates/vertfr.html|archive-date=29. 06. 2011|url-status=dead}}</ref> Сви ови рани кичмењаци нису имали [[Вилица|вилице]] и ослањали су се на храњење близу дна.<ref>{{Cite book|title=The Complete Guide to Prehistoric Life|year=2005|publisher=Firefly Books|author=Tim Haines, T.|last2=Chambers|first2=P.|pages=0}}</ref> Група кичмењака несигурне филогеније, конодонта попут малих [[јегуља]], позната су из микрофосила њихових парних зубних сегмената од касног [[камбријум]]a до краја [[тријас]]a.<ref>{{Cite journal|doi=10.1111/j.1469-185X.1999.tb00045.x|last=Donoghue|first= P.

=== Од риба до водоземаца ===
[[Датотека:Acanthostega BW.jpg|250п|десно|мини|Један од првих кичмењака -{''[[Acanthostega]]''}-]]

Први кичмењаци са вилицама појавили су се у најновијем [[ордовицијум]]у и постали су уобичајени у [[Девон (периода)|девону]], често познатом као „''доба риба''”.<ref name="britannica1954">{{Cite book|title=Encyclopædia Britannica: a new survey of universal knowledge, Volume 17|year=1954|publisher=Encyclopædia Britannica|pages=107}}</ref> Две групе кошчаних [[риба]], [[зракоперке]] и [[саркоптеригије]],{{sfn|Berg|Solomon|Martin|2004|pp=599}} развиле су се и постале уобичајене. Девонци су такође видели пропаст практично свих бешчељусних риба, осим лампреја и тегова, као и -{''Placodermi''}-, група оклопних [[риба]] која је доминирала целим тим периодом од касног [[силур]]ија. Девонски период је такође осведочио пораст првих лабиринтодонта, који су били прелазни облик између [[риба]] и [[Водоземци|водоземаца]].

=== Мезозоични кичмењаци ===
[[Мезозоик|Мезозоични]] кичмењаци, амниоте су се одвојиле од лабиринтодонта у каснијем периоду карбонизма. Парарептилија и синапсидни амниоти били су чести током касног [[палеозоик]]а, док су дијапсиди постали доминантни током [[мезозоик]]а. У мору су доминирале кошчане [[рибе]]; [[птице]], изведени облик [[диносаурус]]а, еволуирале су у [[Јура|јури]].<ref>{{Cite book|last=Cloudsley-Thompson|first=J. L.|title=Ecology and behaviour of Mesozoic reptiles|url=https://archive.org/details/ecologybehaviour00clou|year=2005|publisher=Springer|location=9783540224211|pages=[https://archive.org/details/ecologybehaviour00clou/page/n16 6]}}</ref> Изумирање [[диносаурус]]а, изузев птица, на крају [[Креда (периода)|креде]] омогућило је ширење [[сисар]]а, који су се развили из [[Therapsid|терапсида]], групе синапсидних амниота, током касног [[тријас]]ног период.

=== После мезозоика ===
Након [[Мезозоик|мезозоичних]] кичмењака на свет су дошли [[Кенозоик|кенозоични]] кичмењаци, који су се појавили у доба [[палеоген]]а.

У [[Кенозоик|кенозоичне]] кичмењаке спадају:
* '''[[Рибе]]'''
* '''[[Водоземци]]'''
* '''[[Гмизавци]]'''
* '''[[Птице]]'''
* '''[[Сисари]]'''

== Грађа ==

=== Кожа ===
Кичмењаци имају двобочну ([[Bilateria|билатералну]]) [[Симетрија тела|симетрију тела]]. Основни делови тела кичмењака су глава, труп и реп. Тело им је прекривено вишеслојном кожом која садржи различите жлезде.

На рачун рожног слоја развиле су се у току еволуције разне заштитне творевине као што су [[рожне крљушти]] (покривају тело гуштера и змија), [[рожне плоче]] (корњаче и крокодили), [[перје]], [[длака|длаке]], [[Канџе (зоологија)|канџе]], [[нокти]], [[копита]], [[рогови]] идр. Перје ([[митарење]]м), а длаке лињањем се такође периодично одбацују.

=== Покожица ===
[[Покожица]] (епидермис) се увек састоји од више слојева епителских ћелија које су збијене једна уз другу и граде компактан слој. Број слојева је различит на разним местима на телу, као што је нпр. код човека број слојева већи на длановима и [[Стопало|стопалима]]. Површински слојеви састоје се из сасвим спљоштених ћелија, које постепено изумиру и замењују се новим.

Доњи слојеви покожице који се налазе уз крзно су активни у током целог живота и својим деобама образују горње слојеве ћелија. Они представљају [[герминативни слој]]. У ћелијама горњих слојева покожице долази до процеса орожњавања — ћелије се постепено испуњавају рожном материјом ([[кератин]]ом) што доводи до изумирања тих ћелија. Тако се на самој површини тела образује слој мртвих ћелија — рожни слој. Између рожног и герминативног слоја налазе се прелазни слојеви у којима орожњавање није довршено. Рожни слој има заштитну улогу и нарочито је добро развијен код типичних копнених кичмењака, гмизаваца, птица и сисара, док је код водоземаца релативно танак. Површински рожни слојеви одбацују се стално и делимично ([[перутање]]) или периодично у целини у виду [[пресвлачење|пресвлачења]] (код змија — змијска кошуљица).

=== Мишићни систем ===
Испод [[Кожа|коже]] налазе се снажно развијени мишићи трупа и органа за [[кретање]], који кичмењацима омогућавају велику покретљивост. За разлику од већине [[Бескичмењаци|бескичмењака]], који имају спољашњи скелет, кичмењаци имају унутрашњи скелет. Граде га скелет главе, кичменица, ребра и скелет удова. У главеном делу скелета — лобањи налази се [[мозак]]. Скелет може бити хрскавичав или коштани.

=== Систем органа за варење ===
[[Систем органа за варење]] састоји се од [[Усна дупља|усне дупље]] и [[Crevo (zoologija)|цревног канала]]. Цревни канал кичмењака чине [[ждрело]], [[једњак]], [[желудац]], [[Танко црево|танко]], [[Debelo crevo|дебело]] и право црево које се завршава [[Анус|аналним отвором]] (анусом). Међутим, код неких кичмењака задњи део црева се улива у [[Клоака|клоаку]]. У клоаку се уливају и изводни канали [[Систем за излучивање|система за излучивање]] и [[Репродуктивни систем|размножавање]].

==== Систем за варење риба ====
[[Датотека:Internal organs of a fish.svg|мини|десно|300п|Распоред унутрашњих органа рибе]]

[[Рибе]] храну уносе кроз уста уз помоћ вилица. Већина риба има зубе и непокретан језик (код копнених животиња је много развијенији). Рибе такође немају [[пљувачне жлезде]], јер кроз њихову усну дупљу стално пролази вода. Храна се даље креће кроз ждрело, које је код риба и осталих водених кичмењака више развијено него код копнених и садржи прорезе за [[Комуникација|комуникацију]] са спољашњом средином, те у једњак, па затим у [[Трбух|стомак]]. Ту се одвија делимично варење уз деловање желудачних сокова (који садрже [[Želudačna kiselina|киселине]] и [[ензим]]е), а храна се потом креће кроз црева за даље варење и апсорпцију храњивих материја у крв. Неке рибе имају црева само једне величине, па се код њих не разликују танко и дебело црево. Рибе које су претежно [[месојед]]и обично имају краћа црева од [[биљојед]]а. Отпадне материје излазе кроз [[анус]].

Између стомака и црева постоји структура која обавља функцију [[вентил]]а. Након те структуре канал од [[Јетра|јетре]] и [[Гуштерача|панкреаса]] везује се за црева и до хране доводе ензиме, укључујући и [[пепсин]] и [[трипсин]] (код многих риба панкреас је расут у виду многобројних жлезданих чворова у цревној [[мезентера|мезентери]]). Пепсин и трипсин се не доводе у црева на том месту, већ се формирају и излучују из подслузних ћелија у стомак и црева њиховом целом дужином. У унутрашњости црева налазе се многи [[крвни суд]]ови који упијају храњиве материје. Такође су присутни многи набори да би црева могла садржавати што више крвних судова и да би се повећала додирна површина између хране и крви.<ref>{{cite web|author= |url=http://www.simplydiscus.com/library/biology/anatomy/digestive_system.shtml |title=The Digestive System of the Bony Fish, Ardan Huck |date= |website= |publisher= |access-date = 14. 4. 2018}}</ref>

==== Систем за варење водоземаца ====
[[Датотека:Frog anatomy tags.PNG|мини|десно|240п|Анатомија жабе]]

Многи [[водоземци]] лове плен избацујући свој издужени језик са љепљивим врхом и враћајући га у уста, након чега плен зграбе и вилицама. Неки користе инерцијски начин храњења, што значи да нагло забацују своју [[Глава|главу]] према напред, због чега им се храна у устима креће према назад. Већина водоземаца свој [[Predacija|плен]] гута цео, без много [[Жвакање|жвакања]], па стога поседују врло велике стомаке. Кратки једњак има много [[трепље|трепљи]], које, заједно са слузи из жлезда у устима и ждрелу, потпомажу кретање хране. Ензим [[Hitinaza|хитиназа]] у стомаку помаже при варењу хитинске [[Кутикула|кутикуле]] [[Зглавкари|зглавкара]] које водоземци лове.{{sfn|Dorit | Walker | Barnes | 1991 | p=847 }}

Водоземци поседују панкреас, јетру и жучну кесу. Јетра је обично велика са две округле избочине. Њену величину одређује њена функција као места за складиштење гликогена и масти, а може се мењати кроз годишња доба када се те резерве допуњују или искориштавају. [[Адипозно ткиво]] је још један начин складиштења енергије и јавља се у пределу абдомена, испод коже и, код неких даждевњака, у репу.{{sfn|Stebbins | Cohen | 1995 | p=66 }}

==== Систем за варење гмизаваца ====
[[Датотека:Montpellier snake.jpg|мини|лево|240п|-{''Malpolon monspessulanus''}- једе гуштера. Велика већина гмизаваца су месождери, а неки се претежно хране другим гмизавцима.]]

Већина [[Гмизавци|гмизаваца]] су инсектоједи или месоједи и имају једноставан и кратак дигестивни тракт, будући да су разлагање и варење меса релативно једноставни. Варење се одвија спорије него код сисара, што се одражава на њихов нижи метаболизам одмарања (количина калорија коју би једна јединка потрошила када и спавала цели дан и ноћ) и на њихову немогућност да распарчају и сажваћу храну.<ref>{{Cite book|title=Comparative Physiology: Life in Water and on Land; Nutrient requirement and the design and function of guts in fish, reptiles and mammals |year=1986|publisher=Liviana Press/Springer Verlag|isbn=978-0-387-96515-4|url=http://www.google.no/books?hl=no&lr=&id=zuT5z5cPWhcC&oi=fnd&pg=PA181&dq=reptiles+carnivory+gastric&ots=MHgrO9g5DV&sig=egenLtkWuXaLf17he67k0O8ARSY&redir_esc=y#v=onepage&q&f=false|last=Karasov|first=W.

Иако су данашњи гмизавци претежно месоједи, у раном периоду развоја гмизаваца постојало је неколико група које су изродиле [[мегафауна|велике биљоједе]]: у [[палеозоик]]у су то били [[парејасаури]] и [[дисинодонти]] (кладус -{[[Synapsida]]}-), а у [[мезозоик]]у неколико група [[диносаури|диносаура]].<ref name="SahneyBentonFerry2010LinksDiversityVertebrates">{{cite journal|url=http://rsbl.royalsocietypublishing.org/content/6/4/544.full.pdf+html|last=Sahney|first=S.|last2=Benton|first2=M.

Гмизавци биљоједи суочавају се са истим проблемима као и сисари биљоједи, али будући да немају њихове сложене зубе, многе врсте гмизаваца гутају камење ([[гастролит]]е) који им помажу у варењу: то камење креће се по стомаку и тако меље биљне материје.<ref name="herbivory" /> Фосилизовани гастролити пронађени су уз скелете [[орнитоподи|орнитопода]] и [[сауроподи|сауропода]], мада није сигурно утврђено да ли су код последње групе имали функцију у варењу.<ref>{{cite journal|last=Wings|first=O. |last2=Sander|first2=P.

Код птица се желудац састоји из жлезданог (жлезде луче [[Пљувачка|пљувачку]] и ензиме) и механичког дела ([[бубац]]). Бубац је веома мишићав и обложен чврстом превлаком која помаже у дробљењу хране, чиме се надокнађује недостатак зуба. Осим тога, птице имају два [[Слепо црево|слепа црева]].

Исхрана птица врло је разнолика, те укључује [[нектар]], [[воће]], [[биљке]], [[семе]], стрвине и многе мале животиње, укључујући и друге птице.<ref name="Gill">{{harvnb|Gill|1995|pp=}}, Приступљено 14. април 2018.</ref> Будући да птице немају зубе, њихов систем за варење прилагођен је варењу необрађене хране, коју оне најчешће гутају целу.

Птице које се хране на више различитих начина или имају врло разнолику прехрану називају се генералистима, док се друге, које концентришу време и труд на прибављање појединих типова хране или имају само један начин на који то раде, називају специјалистима.<ref name="Gill" /> Начини прехране код птица варирају од врсте до врсте. Многе прикупљају инсекте, бескичмењаке, воће или семе са дрвећа или тла. Неке лове [[Инсекти|инсекте]] изненадним нападом са гране. Оне врсте које се хране инсектима-штеточинама сматрају се благотворним „агентима биолошке контроле” и њихово се присуство подстиче у програмима биолошке контроле штеточина.<ref name="lwa001">{{Cite web|url=http://lwa.gov.au/files/products/land-water-and-wool/pf061365/pf061365.pdf |title=Birds on New England wool properties – A woolgrower guide |accessdate=17. 7. 2010 |publisher=Australian Government – Land and Water Australia |work=Land, Water & Wool Northern Tablelands Property Fact Sheet |last=Reid |first=N |format=PDF |year=2006 |archive-url=https://web.archive.org/web/20110315005353/http://lwa.gov.au/files/products/land-water-and-wool/pf061365/pf061365.pdf |archive-date=15. 3. 2011 |url-status=dead }}, Приступљено 14. април 2018.</ref> Птице које се хране нектаром, као што су [[колибрији]], [[медосаси]], [[лорији]] и други, развили су посебно прилагођене четкасте језике, а код многих се чини да су кљунови коеволуирали искључиво са оним врстама цвећа којим се хране.<ref>{{Cite journal|last=Paton|first=D.

==== Систем за варење сисара ====

===== Месоједи =====
====== Усна шупљина ======
Усна шупљина месождера има велик отвор. При лову развијају велику снагу и кидају месо ловине. [[Мишићно ткиво|Мишићи]] лица су слабији. Вилична веза је једноставна спона у висини [[зуби|зуба]] и та врста везе је стабилна. [[Сљепоочни мишић]] је главни мишић који покреће вилице [[месождер]]а. Тај је мишић одговара већем делу обима главе. [[Угао]] горње вилице им је мали јер жвачни и споначни мишић који су ту причвршћени немају велику важност за ове животиње.

Доња вилица не може се покретати напред, а њено кретање с једне стране на другу је ограничено. Кутњаци имају оштрице. При затварању вилица кутњаци клизе једни према другима. Тако се ствара механизам за трзање меса с [[кост]]ију. Зуби месождера су раздвојени тако да се на њима не задржавају комадићи меса. [[Секутићи]] су ситни и зашиљени. Служе за хватање жртве и за ситњење. [[Очњаци]] су прилично издужени. Њима животиња рањава, трза и убија свој улов. Кутњаци су спљоштени и у облику троугла са зупчастим ивицама. Због способности вилица да се расклапају, кутњаци горње и доње вилице се спајају од позади према напред.

[[Пљувачка]] код месождера не садржи [[ензим]]е за варење. Кад месождер сисар гута храну, он је не жваће. Ензими за верење [[беланчевина]] не могу се ослободити у устима (постоји опасности да се уништи и усна шупљина-аутоварење). Месождери не мешају храну са пљувачком. Они откидају велике комаде меса те их такве гутају, без уситњавања.

===== Биљоједи =====

====== Усна шупљина ======
Код сисара биљоједа добро су развијени мишићи лица, који се састоје од дебелих меснатих усни, релативно малог усног отвора и задебљалог мишићавог језика.

Усне помажу при довођењу хране у уста. Мишићима лица и језиком потпомажу обраду хране. Спој две вилице налази се изнад висине зуби. Овај спој је мање стабилан него код месождера, покретнији је, а тиме омогућава сложене покрете вилица потребне за жвакање биљне хране. Овакав спој вилица омогућава да се код затварања уста поклопе горњи и доњи кутњаци и дуж целе вилице, и тако омогућава млевење хране. Оваква врста споја вилица је важна за животиње које се хране биљкама.

[[Слепоочни мишић]] је мали и он има малу важност. Жваћни и спонски мишићи држе горњу вилицу и њишу је с једне стране на другу. Доња вилица креће се у страну. Такво бочно кретање вилице потребно је за мрвљење хране при жвакању.

Распоред зуба варира од врсте до врсте, зависно од вегетације којом се та одређена врста храни. Иако се те животиње разликују по броју и обележјима зуба, зубала им показују неке заједничке структурне црте. Секутићи су широки, спљоштени и ромбоидни. Очњаци могу бити ситни, истакнути и потпуно одсутни. Кутњаци су четвртасти и спљоштени с горње стране да би пружили површину за млевење хране. Не клизе једни крај других окомито већ клизе једни преко других водоравно, ломећи и уситњавајући храну. Површина кутњака се разликује међу врстама зависно од биљки којима се хране. Зуби су им уско груписани. Тако секутићи стварају механизам помоћу којег гризу, брсте делове биљака, а горњи и доњи кутњаци чине платое за дробљење и млевење хране. Оваква шупљина има велике могућности ширења простора што се и реализује у току једења.

Пажљиво жваћу храну, гурајући је језиком и мишићима лица напријед-назад међу зубе за млевење и уситњавање. Такав темељни процес потребан је да би се механички разбио ћелијски зид биљне ћелије. Омогућава им да сварљив садржај из ћелије изађе и помеша се са пљувачком. Мешање хране са пљувачком је врло важно јер пљувачка сисара-биљоједа садржи ензиме за разградњу угљених хидрата, који разграђују молекуле хране док је она још у устима.

=== Систем органа за излучивање ===
Органи за излучивање кичмењака чине бубрези, мокраћоводи и мокраћна цев којом се мокраћа излива у спољашњу средину и клоаку. Већина копнених кичмењака има и мокраћну бешику у којој се сакупља мокраћа.

Улога органа је излучивање [[азот]]них продуката размене материја као и регулисања количине течности, [[со]]ли и других материја у организму. Врло су значајни за одржавање сталног састава крви ([[хомеостаза]]).

Код кичмењака се јављају три типа бубрега који се смењују током [[ембрионално развиће|ембрионалног развића]]. Код нижих се јављају две генерације бубрега.

=== Размножавање ===
Кичмењаци се размножавају [[Polno razmnožavanje|полно]]. Систем органа за размножавање чине полне жлезде и полни одводи. Мушке полне жлезде су семеници. У њима настају [[сперматозоид]]и. Женске полне ћелије су [[Јајник|јајници]]. У њима настају женске полне ћелије — јајне ћелије. Оплођење може бити спољашње. Унутрашњем оплођењу претходи парење.

=== Крвни систем ===
[[Крвни систем]] кичмењака чине [[срце]] и [[крвни суд]]ови. Срце кичмењака грађено је од делова који се називају преткоморе и коморе.

Срце је орган које пумпа и потискује крв кроз крвне судове. Крв доноси ћелијама [[кисеоник]], хранљиве и друге неопходне супстанце, а из њих односи штетне супстанце и [[угљен-диоксид]].

Црвена боја крви потиче од пигмента [[хемоглобин]]а.

=== Нервни систем ===
Основна организацијска и функцијска јединица нервног система је нервна је ћелија или [[неурон]]. Састоји се од звездастог тела са једром и нервних наставака. То су (1) кратки — дрволико разгранати дендрит и (2) дужи неурит или нервно влакно, који се на крају такође грана. Дендрити преносе импулсе (подстицаје, подражаје) ка телу неурона, а аксони — од тела ка дендриту суседног неурона или ефектору. Међусобни спој суседних нервних ћелија остварује се функционалном везом дендтита једне са неуритом друге и то преко [[синапса|синапсе]] или спојнице.<ref>{{Cite book|last=Nikoletseas M. M.|title=Behavioral and neural plasticity|year=2010|isbn=978-1-4537-8945-2|pages=}}</ref>

Периферни нерви састављени су од аксона који се пружају читавом њиховом дужином па код човека могу достићи дужину и преко 1 м. [[Мозак|Мождане]] и мождинске нерве чине снопови кратких аксона, а у осећајним и аутономним нервима, тела неурона се удружују у специјалне чвориће — ганглије.<ref>Međedović S., Maslić E., Hadžiselimović R. : Biologija 2. Svjetlost, Sarajevo. {{page|year=2000|isbn=978-9958-10-222-6|pages=}}, Приступљено 14. април 2018.</ref><ref>Hadžiselimović R., Maslić E. : Osnovi etologije — Biologija ponašanja životinja i ljudi. Sarajevo Publishing, Sarajevo. {{page|year=1999|isbn=978-9958-21-091-4|pages=}}, Приступљено 14. април 2018.</ref>

Преношење нервних импулса дуж неурона остварује се протицањем наелектрисаних честица — [[јон]]а кроз мембрану неурита. Непобуђена нервна ћелија је електрично [[поларност|поларизована]], јер унутрашњу и спољну страну њене опне одликују различити — позитивни и негативни набоји. То је последица разлика у концентрацији [[натријум]]ових и [[калијум]]ових јона на супротним странама опне. Висока унутрашња концентрација калијума, а ниска натријума, праћена је обрнутим смером њихових спољних концентрација. У моменту подражаја, мења се распоред [[молекул]]a у мембрани па она постаје пропустљива за излазеће калијумове и улазеће натријумове јоне. Мембрана губи поларизацију — деполаризује се — а настали електрични набој ([[акциони потенцијал]]) доводи до промене односа концентрација ових јона у њеном суседном делу, који се такође деполаризује. Деполаризовани део мембране је електронегативан у односу на поларизирани. Зато се између њих ствара струјно коло па се рецепторски импулс шири као талас деполатизација, који брзо напредује дуж нерва.

==== Шкрге ====
[[Датотека:Tuna Gills in Situ 01.jpg|294п|десно|мини|Шкрге код туње ([[рибе]])]]
Шкрге ({{јез-лат|branchia}}) код водених кичмењака (риба и ларви водоземаца) и [[бескичмењаци|бескичмењака]] функционишу као респираторни органи, док се код копнених кичмењака јављају само у току [[онтогенетско развиће|ембрионалног развића]], а касније се редукују.

Код кичмењака шкрге су [[ендодерм]]алног и [[мезодерм]]алног порекла могу да буду:
* Унутрашње које настају као евагинације унутрашњег зида [[Ждрело|ждрела]] и образују се код риба
* Спољашње које полазе са спољашњег зида ждрела и карактеристичне су за [[ларва|ларве]] [[водоземци|водоземаца]]

==== Плућа ====
[[Датотека:Heart-and-lungs.jpg|294п|лево|мини|Плућа и срце код кичмењака]]

Плућа кичмењака су по правилу парна, састоје се од два плућна крила (изузетак су [[змије]] код којих је једно плућно крило закржљало). Плућа сувоземних кичмењака су врло слична рибљем мехуру плућашица. Она стоје у вези са цревом преко [[душник]]а, који се отвара у ждрелу једним пукотинастим отвором. Изнад тог отвора је код сисара развијен израштај у виду поклопца (епиглотис), који затвара улазак у душник за време гутања. Почетни део душника, у нивоу отвора, је [[гркљан]]. Гркљан, нарочито код сисара, функционише као гласни орган захваљујући гласним жицама, које се протежу у његовој унутрашњости. Зид душника је подупрт хрскавичавим прстеновима. На свом крају душник се грана на бронхије које се даље гранају у самим плућима. Код птица је на месту гранања душника смештен орган који производи глас.

Плућа су нарочито сложене грађе код птица и сисара. Код птица од плућних крила полазе проширења — ваздушне кесе, чији израштаји залазе између унутрашњих органа и у [[кост]]и. Оне смањују специфичну [[Тежина|тежину]] тела и учествују у дисању за време летења. Приликом лета, грудни кош птица се не шири, па покрети грудног мишића изазивају ширење и скупљање кеса.

Код сисара плућа леже у грудној дупљи која је од трбушне одвојена дијафрагмом. Ваздух доспева у плућа покретима грудног коша. Његовим наизменичним ширењем и враћањем у првобитну запремину мења се и запремина плућа. У тим покретима учествују:
* Инспираторни мишићи учествују у ширењу грудног коша, односно, удисају (инспиријум); главни међу њима су:
** Спољашњи међуребарни мишићи
** [[Дијафрагма]]
* Експираторни мишићи помажу издисај (експирација); припадају им:
** Унутрашњи међуребарни мишићи
** Трбушни мишићи

[[Bronhija|Бронхије]] се у плућима гранају на бронхиоле које се завршавају плућним мехурићима чији зидови образују коморице — [[Плућна алвеола|алвеоле]]. Алвеоле су танких зидова и богате мрежом [[капилар]]а и представљају респираторну површину преко које се врши размена [[гас]]ова.

=== Чулни органи ===
[[Око|Очи]] кичмењака припадају мехурастом типу и могу бити:
* непарне очи — има их мали број кичмењака и то као темено (колоусте, неке рибе и [[гуштери]]) и пинеално око (код колоуста, а код осталих кичмењака је претворено у епифизу);
* парне очи.

==== Парне очи ====
Изграђене су по типу затвореног очног мехура ([[очна јабучица]]). Очна јабучица обавијена је са три опне:
# [[беоњача|беоњачом]] — спољашња опна, која на предњем крају образује провидну рожњачу;
# [[судовњача|судовњачом]] — богата крвним судовима; на предњем крају образује [[дужица|дужицу]] (различито обојена) која на средини има отвор — зеницу; иза дужице лежи [[очно сочиво]];
# [[мрежњача|мрежњачом]] (ретина) —унутрашња опна; она је најсложенији део ока; у њој се налазе [[чулна ћелија|чулне ћелије]]:
:* ''[[Štapićasta ćelija|штапићи]]'' — одговорни за разликовање [[светлост]]и и [[Тама|таме]]; код сисара су бројнији од чепића;
:* ''[[Kupasta ćelija|чепићи]]'' — одговорни за уочавање боја и детаља предмета; највише их има у средини [[Мрежњача|мрежњаче]] (на линији која пролази кроз центар ока) на месту које се зове [[жута мрља]] — место најоштријег вида.

== Разноврсност кичмењака ==
{{главни чланак|Кичмењаци без вилица|Кичмењаци са вилицама}}

Кичмењаци су на основу заступљености вилица подељени у две основне групе:
# [[кичмењаци без вилица]]
# [[кичмењаци са вилицама]]

У кичмењаке без вилица спадају колоусте и остракодерми.

=== Кичмењаци без вилица ===

==== Колоусте ====
[[Датотека:Lampetra fluviatilis.jpg|294п|десно|мини|-{''[[Lampetra fluviatilis]]''}- (кичмењак без вилице)]]
Ова поткласа обухвата мали број рецентних морских и слатководних врста које су према спољашњој морфологији веома сличне [[јегуље|јегуљама]] од којих се разликују далеко примитивнијом грађом. [[Кожни систем|Кожа]] им је слузава и без крљушти обојена сиво — мрко. Дужине су до 1 -{m}-. Крећу се вијугањем тела и често се припијају за пливајуће предмете и објекте.

Назив добиле према усном отвору који је, услед недостатка [[вилица]], стално отворен и округао. У усном отвору се налазе многобројни рожни [[зуб]]ићи. Поред недостатка вилица ове животиње немају ни парне удове већ само једно недиференцирано непарно [[пераје]] у виду кожног набора који је изнутра подупрт хрскавичавим елементима. Унутрашњи [[скелетни систем|скелет]] је представљен [[Хорда (биологија)|хордом]] (-{chorda dorzalis}-) која је обавијена чврстом везивном опном. Поједини делови хорде су [[хрскавичаво ткиво|хрскавичави]] и [[метамерија|метамерно]] распоређени. Лобања је врло просте грађе и састоји се од неколико хрскавичавих елемената. Одозго, на средини главе налази се само један [[носни отвор]] по чему се називају и -{[[Кичмењаци без вилица|Monorhini]]}-. [[Мозак]] је петоделан и са њиме су у вези ендокрине жлезде: [[епифиза]] и [[хипофиза]].

Шкрге се састоје од листића који леже у шкржним кесама. [[Срце]] се налази у [[перикард]]ијуму и састоји од преткоморе и коморе. Црево је у облику праве цеви на којој нема желуца. [[Јетра]] је развијена док је [[гуштерача|панкреас]] у зачетку. [[Слезина]] не постоји, већ је уместо ње у зиду црева присутно [[лимфоидно ткиво]]. Излучивање врше парним [[мезонефрос]]има чији се изводни канали изливају заједничким отвором који се налази иза аналног отвора.

Већина колоуста је одвојених полова. [[Полна жлезда|Полне жлезде]] су непарне и немају изводне канале па се полни продукти избацују у [[телесна дупља|телесну дупљу]] да би у спољашњу средину биле избачене преко урогениталног синуса који се налази иза аналног отвора. Развиће се одвија [[Метаморфоза у биологији|метаморфозом]] преко [[ларва|ларве]] [[змијуљице|амоцетес]] (-{ammocoetes}-). Ларве се толико разликују од одрасле јединке да су раније биле описиване као засебна врста. Живе на дну заривене у [[песак]] по чему су и добиле име.

Велики број врста су [[ектопаразити]] [[рибе|риба]]. Помоћу рожних зубића се причвршћују за тело домаћина и помоћу језика, који служи као пумпа, сишу крв.

Циклостоми се деле на два реда:
* [[слепуље]] или -{Myxinoidea}-;
* [[змијуљице]], (називају се још [[змијуљице|вијуни]] или [[змијуљице|пакларе]]) или -{Petromyzontes}-.

==== Остракодерми ====
[[Кичмењаци без вилица|Остракодерми]] су најстарији прапреци кичмењака познати у [[фосил]]ном стању. Фосили се могу наћи у слојевима земље из периода од [[ордовицијум]]а до [[Девон (периода)|девона]]. Као и њихови сродници колоусте нису имали парне удове и вилице. За разлику од колоуста имали су добро развијен кожни скелет, односно њихова кожа има коштане плочице или крљушти по чему су добили име. Снажно развијени коштани оклоп омогућио је њихову јако добру фосилизацију. То су биле слабо покретне животиње, лоши пливачи које су већину живота проводиле на дну слатких вода. Скелет им је био хрскавичав.

Деле се на четири реда:
# [[остеостраци]] (-{Osteostraci}-)
# [[анаспида]] (-{Anaspida}-)
# [[хетеростраци]] (-{Heterostraci}-)
# [[целолепида]] (-{Coelolepida}-)

=== Кичмењаци са вилицама ===

==== Рибе ====
[[Датотека:Carcharhinus melanopterus Luc Viatour.jpg|250п|десно|мини|''[[Ајкула]]'' (рибе)]]

Рибе ({{јез-лат|Pisces}}) ектотермни су водени кичмењаци који живе готово искључиво у [[вода|води]]. Наука која се бави рибама зове се [[ихтиологија]]. Постоји преко 33.100 [[Врста (биологија)|врста]] риба,<ref>{{cite web|publisher=[[FishBase]]|url=http://www.fishbase.org/search.php|title=FishBase |year=2015|accessdate=29. 8. 2015}}, Приступљено 14. април 2018.</ref> што их чини највећом групом кичмењака. Око половине свих кичмењака су рибе, најстарији познати [[фосил]]и су стари 450 милиона година. За кретање им служе парна и непарна [[пераја]]. Дишу [[шкрге|шкргама]], а [[срце]] им има једну преткомору и једну комору и кроз њега протиче редукована [[крв]]. Немају мали крвоток. Најразвијенији део [[мозак|мозга]] је мали мозак. Кичменица је образована и може бити хрскавичава или окоштала. Оплођење је спољашње, а врсте по основу доношења младих могу бити овипарне, ововивипарне и вивипарне.<ref name="integrated">{{Cite book|last=Hickman|first=Cleveland P., Jr. |last2=Roberts|first2=Larry S.|last3=Larson|first3=Allan L.|title= Integrated Principles of Zoology|publisher=McGraw-Hill Publishing Co|year=2001|isbn=978-0-07-290961-6|pages=}}</ref>

==== Водоземци ====
[[Датотека:Australia green tree frog (Litoria caerulea) crop.jpg|250п|лево|мини|''[[Жаба]]'' (водоземци)]]

Водоземци или амфибије ([[Латински језик|лат.]] Amphibia) су први становници копна међу кичмењацима ([[копнени кичмењаци]]) и истовремено њихови [[еволуција|еволуционо]] најнижи представници. Прва велика група водоземаца развила се у периоду [[Девон (грофовија)|девона]], пре око 370 милиона година, од [[Саркоптеригије]] сличним [[целеканти]]ма и [[дводихалице|дводихалицама]],<ref name="evoamphib">{{cite web |url=http://sci.waikato.ac.nz/evolution/AnimalEvolution.shtml#evolutionofamphibian |title=Evolution of amphibians |publisher=University of Waikato: Plant and animal evolution |accessdate=30. 9. 2012 |archive-date=27. 06. 2016 |archive-url=https://web.archive.org/web/20160627175302/http://sci.waikato.ac.nz/evolution/AnimalEvolution.shtml#evolutionofamphibian |url-status= }}, Приступљено 14. април 2018.</ref> код којих су се развила пераја слична ногама, са више зглобова и прстију, што им је омогућавало пузање по морском дну. Неке рибе развиле су примитивна плућа како би могле дисати, будући да су стагнантни базени у девонским [[мочвара]]ма садржавали врло мало кисеоника. Снажним перајима су се такође могле извући из воде на копно уколико је то било потребно. На крају ће се њихова коштана пераја развити у удове те ће оне тиме постати преци свих [[tetrapodi|тетрапода]], у које спадају данашњи водоземци, [[гмизавци]], [[птице]] и [[сисари]]. Упркос томе што су могле пузити по копну, многе од тих праисторијских тетраподоморфних риба и даље су проводиле већину времена у води. Почеле су развијати плућа, али још увијек су већином користиле шкрге.<ref name="Carroll">{{harvnb|Carroll|1977|pp=405–420}}, Приступљено 14. април 2018.</ref>

==== Гмизавци ====
[[Датотека:Sphenodon punctatus in Waikanae, New Zealand.jpg|250п|десно|мини|''[[Рептил]]'' (гмизавци)]]

Гмизавци ({{јез-лат|Reptilia}} — Рептили) су одиграли изузетно значајну улогу у историји развоја животињског света, јер је то прва група кичмењака која је у потпуности изашла на [[копно]]. Ова еволуција омогућена је захваљујући развитку [[јаје|јаја]] са амнионом: опна ([[амнион]]) је обавијала [[ембрион]] који се налазио у течној средини, па је ембрион могао да се развија лебдећи у течности, а није било потребно да се јаја полажу у води. Рептили су [[тетрапод]]на животињска [[Класа (биологија)|класа]] која се састоји од [[корњача]], [[крокодил]]а, [[змија]], [[Amphisbaenia|водених гуштера]], [[гуштер]]а, [[Туатаре|туатара]], и њихових изумрлих сродника. Изучавање тих традиционалних рептилских [[Ред (biologија)|редова]], историјски комбинованих са модерним [[водоземци]]ма, се назива [[херпетологија]].

==== Птице ====
[[Датотека:Blue Tit aka.jpg|250п|лево|мини|''[[Плава сеница]]'' (птице)]]

Птице ({{јез-лат|Aves}}) су [[класа (биологија)|класа]] двоножних, топлокрвних кичмењака који полажу [[јаје|јаја]]. Птице су током [[јура|јуре]] еволуирале од [[диносаури|диносаура]] подреда [[тероподи|теропода]], а најранија позната птица из касне јуре је -{''[[Archaeopteryx]]''}-.<ref name="brown2011">{{cite journal|last=Brown|first=J. W.|author2=Van Tuinen, M.  |lastauthoramp=yes |year=2011|title=Evolving Perceptions on the Antiquity of the Modern Avian Tree, in Living Dinosaurs |publisher=John Wiley & Sons LtD |doi= 10.1002/9781119990475.ch12 |journal=The Evolutionary History of Modern Birds |isbn=978-1-119-99047-5 |pages=306–324}}, Приступљено 14. април 2018.</ref> По величини варирају од ситних [[колибри]]ја до крупних [[ној]]ева. Постоји између 10 и 11 хиљада познатих врста птица и најразноврснији су класа међу [[копнени кичмењаци|копненим кичмењацима]].

Многе птичје врсте сваке године крећу на [[Миграција (зоологија)|селидбе]] у удаљене крајеве, а још више их предузима миграције које су краће и мање регуларне. Птице су друштвене животиње и комуницирају визуелним сигналима, звучним позивима и певањем, учествују у друштвеном понашању што укључује заједнички лов, помоћ при одгајању подмлатка и понашање карактеристично за јато. Неке врсте птица су искључиво моногамне, друге првенствено моногамне уз повремено [[парење]] с другим јединкама. Друге врсте су [[Полигинија|полигине]] или [[Полиандрија|полиандричне]]. Јаја обично полажу у [[гнездо|гнездима]] где се она инкубирају, и већина птица дуже време проводи у подизању младих након излегања.

Људи искориштавају птице као важан извор хране кроз лов и [[живина]]рство. Неке врсте, првенствено певачице и [[папагај]]и омиљене су као [[кућни љубимац|кућни љубимци]]. Птице су истакнуто заступљене у свим погледима људске културе, од [[религија|религије]], [[поезија|поезије]] до популарне музике. Око 120 до 130 птичјих врста изумрло је као резултат људског деловања од 1600. године, а пре тога још и више. Данас многим врстама птица прети [[изумирање]] због деловања људи и врше се напори како би се заштитиле.

Данашње птице одликују [[перје]], [[кљун]] без зуба, полагање јаја са чврстом љуском, висока стопа [[метаболизам|метаболизма]], срце с две коморе и две преткоморе, те лаган, али јак [[скелет]]. Многе птице имају предње удове развијене као крила којима могу летети, иако су нојевке и неколико других, углавном [[ендем]]ских оствских врста, изгубиле ту способност.

==== Сисари ====
[[Датотека:Mammal Diversity 2011.png|250п|десно|мини|[[Сисари]]]]

Сисари ([[Латински језик|лат.]] -{Mammalia}-) су класа кичмењака коју карактеришу присуство [[длака]] и способност женке да производи [[млеко]] (које служи за исхрану младунаца). Постоји око 5500 савремених [[врста (биологија)|врста]] сисара сврстаних у око 1200 [[род (биологија)|родова]]. Сисари су [[Хомеотерми|ендотермни]] кичмењаци који настањују веома разнолике [[еколошка ниша|еколошке нише]], углавном на копну<ref name="kalezic">Калезић, М., Томовић, Љ. Хордати. Београд: ННК Интернационал. {{page|year=2007|isbn=978-86-83635-63-4|pages=309}}</ref>. Постоје и секундарно водене групе ([[китови]], [[морске краве]], [[перајари]]).

Сисари су потомци [[Синапсиди|синапсида]] звероликих гмизаваца, који су настали пре око 300 милиона година. Први сисари у ширем смислу речи појавили су се пре отприлике 225 милиона година, у доба [[тријас]]а и доминације [[Диносауруси|диносауруса]]. Постепено су се диференцирале три савремене групе сисара: [[торбари]], [[кљунари]] и [[placentalni sisari|плацентални сисари]]. Од првобитно ситних ноћних (ноктуралних) животиња сисари, након великог изумирања гмизаваца крајем [[Мезозоик]]а, подлежу [[адаптивна радијација|адаптивној радијацији]] и данас мноштво [[животна форма|животних форми]] живи у већини [[екосистем]]а планете [[Земља|Земље]].
