I yonyango glands omzimba womntu: iimpawu anatomofiziologicheskie kunye nokubaluleka komsebenzi

UmMiselo kwemisebenzi ezixhasa imisebenzi ebalulekileyo umzimba womntu, kuyafikelelwa ngeendlela ezimbini bohluke kuzo ngokupheleleyo. Okokuqala - le indlela humoral zolawulo, yona ekuqaleni, ukuba ivavanye isakhiwo kwaye zisebenza omzimba womntu ngokubhekiselele kuphuhliso phylogenetic. Indlela yesibini dyondzisaka kwaye zikwazi ukukhawulelana neenguqu ezikwimeko yomzimba. Lo mmiselo luvo, eyona nto leyo kuncitshiswa nemisebenzi ulungiso i ebandakanya ikhaliphe visceral neuropathy, ngoxa kwesiphumo into humoral zisabela iimolekyuli neurotransmitter evela izakhiwo iseli receptor kwizigqeba target. Enigcoba transmission signal kwenziwa neemolekyuli zebhayoloji, ukuba Yindibanisela aba bakhoyo apha esinobubovu ezidalwe umzimba. Bathi izithako ukuba kungawunwenisa egazini ukuya kumgama othile ukusuka ingaba nefuthe phantsi kolawulo nabasemagunyeni.

amadlala Ezingokuqandusela: isakhiwo inkqubo ummiselo humoral

Uxanduva ukusebenza kakuhle zonke iinkqubo kunye namaziko indoda ithwala ingqondo, nto leyo liziko ephezulu ukuhlaziya ulwazi engenayo kunye nesayithi ye Yindibanisela imiyalezo ethunyelwe iiseli ekujoliswe ngentla nkqubo zimbini. Ke ukuba impembelelo luvo bafakela ngokusebenzisa links multiple on uhlobo ozahluleleyo ngelaphu, le aposredstvenno humoral waqonda ngenxa ukuthutha molekyuli bioactive ekwaziyo isebenze kwizakhiwo receptor iiseli ngokwamalungu target. Kulo mzekelo, kwamadlala ezidalwe zilungiswe ngendlela ekhethekileyo, yaye oku eyahlukileyo kuyaphi ukusuka exocrine. Okokuqala, amadlala exocrine cell molekyuli babo, oko kukuthi, kokusingqongileyo. Oku kufuna imibhobho ezikhethekileyo excretory, okuye iiseli secretory ingaba ezidalwe awawaphalazayo iihomoni ngqo kwi egazini.

Kubalulekile ukuba iziko ephakamileyo ummiselo humoral ukho ebuchotsheni, oko kukuthi le ngxenye. Lakhe inyama glandular imvelaphi umbefu synthesizes statins, abangaphangeliyo ukuba Yindibanisela hormone yebhinqa, kwaye liberiny okunxamnye ukuliguquguqula umsebenzi wayo. Ngale ndlela eya kumacala amabini kufikelelwe ukulawula imisebenzi lonke kwinkqubo yonyango namadlala omzimba. ummiselo Ngaloo hormone lomnye imisebenzi iziko yi yebhinqa - isakhiwo, malunga 20 amaxesha incinane ngxenye, kodwa wenza imisebenzi enjalo kuyimfuneko. Kwakhona Kuyaphawuleka ukuba ingaba omncinane enze Yindibanisela iikhompawundi macromolecular kukuninzi, leyo ibizwa iihomoni, lo gama isakhiwo-kwinqanaba eliphezulu Ikhupha statin kuphela liberinami ukuba isakhiwo imichiza elula kakhulu, njengoko a dipeptide.

Enye ezidalwe nobubovu elawulwa nje le yebhinqa kunye secretion lomjikelo ixhomekeka umsebenzi Yindibanisela iihomoni utshixelo. Ngoko enye neurohypophysis kuhlanganiswa adh regulatory reabsorption neemolekyuli amanzi kwizintso ukuqokelela imibhobho of nephrons, kunye yioxytocin, ophethe izishunqulelo zesibeleko ngexesha yabasebenzi, kunye namadlala mammary of secretion ubisi. Adenohypophysis okanye lobe Icipande endlaleni ulawula ekukhuleni iinkqubo eziphilayo umjikelo secretion of hormone , yi decarboxylation kwi Medulla adrenal, kuyondelelaniswe ka emzimbeni steroid kwi uthinte adrenal.

Kakhulu amalungu ebalulekileyo nabantu injeke kunye gonads. Ngokutsho isakhiwo kunye nemisebenzi - yinto uhlobo nobubovu secretion engumxube, okt ukuba amaziko umzimba, ezinye ezo uhlobo secretion yonyango, kwaye eyesibini - eccrine. Ngoko gonads abelwe iiseli intsholongwane kokusingqongileyo, iihomoni kodwa iqukuqela igalele ngqo kwi egazini. umsebenzi Ngaloo ndlela yonyango zepancreas ukuba nokulungelelanisa kunciphisa glucagon, insulin somatostatin, exocrine - ehlaziya amylases kunye peptidases ukwenzela ukwetyisa ngo-12 duodenum. Ngenxa zepancreas, kanye njengokuba gonads - it exocrine ezidalwe gland ngaxeshanye.
