Sakhiwo umsebenzi nezindlala adrenal emzimbeni womuntu

I nezindlala adrenal zibhangqwe endocrine nezindlala. Basuke esisogwini izingxenye engenhla izinso esifundeni 11-12 amathambo thoracic. umsebenzi adrenal emzimbeni womuntu - ukukhipha lingene egazini yenombolo hormone ezibalulekile adingekayo ukuze zikwazi ukuphila okuvamile.

Isakhiwo nezindlala adrenal

I kwesokunxele indlala adrenal omdala kuyinto ucezu emise, kwesokudla - esingunxantathu. Bobabili nezindlala adrenal kuthiwa ebiyelwe capsule mncane fibrous. Ubude befinyelela 7 cm ububanzi - 3.5 cm ukushuba kuziwa 8 mm .. Isisindo sawo ngokwesilinganiso imayelana '14 Kusukela adrenal ehlukana izinyanda sezicubu zezinzwa nge izinzwa futhi imithambo yegazi. Igazi kugeleza imithambo ngamaqembu amathathu, futhi outflow yayo senzeka ngemithambo emaphakathi kanye ezingabalulekile. Emzimbeni ingxenye 2 isehlane. I yangaphandle okuyingxenye siqukethe cortex, futhi u-90% isisindo isamba adrenals. endaweni Cortical yena, ihlukaniswe yaba 3 esishintshashintshayo: glomerular, Beam, anezikhala. It iqalise nezindlala adrenal ukuthuthukisa steroid, ngama-corticosteroid futhi hormone ocansini. Ngaphakathi umzimba ugcwele medulla futhi siqukethe amaseli amaningi ezinzwa. Ngesisekelo izinto ezifanayo bakha amaseli chromaffin. La mangqamuzana avumela ukuba ukuqaliswa imisebenzi adrenal ku ukuthuthukiswa kwama-hormone catecholamine: Dopamine, norepinephrine futhi epinephrine.

Inani adrenal umzimba emzimbeni womuntu

I nezindlala adrenal secrete eziningi hormone elawula izinqubo umzimba. Ngokwesibonelo, ama-hormone glucocorticoid neqhaza umzimba carbohydrate emzimbeni. Nge overabundance zabo zingase ukuthuthukisa sikashukela. ezilungisiwe kahle kanye nokwahlukana izicubu adipose. Ama-hormone ekhiqizwa nezindlala adrenal ukulawula inani nendawo imali yayo.

umsebenzi adrenal e ukulawulwa kwamanzi-usawoti ibhalansi

Ngenxa yalaba nezindlala ukukhiqiza ukulawula egcina amanzi emzimbeni futhi ukuqaliswa amaminerali umzimba. Le nqubo lihlobene eduze umsebenzi nezinso izinto ezithathwa kwemiqondo kuyo. Noma yimuphi thuthuva kulesi simiso zigcwele ngokweqile uketshezi ekuqongeleleni, ephakeme blood pressure, futhi nokwehluleka ukusebenza kwezinso.

umsebenzi adrenal e ekukhiqizweni kwama-hormone ocansini

Ngo cortex, kubhekwe nezindlala abhanqiwe akhiwa androgens futhi estrogens - besilisa hormone ocansini nowesifazane. Bathonya umsebenzi zokuzala, kanye olufanele ukuze kwakhiwe izici ngokobulili yesibili. Ngokwesibonelo, androgens nomthelela ukukhula izinwele kanye nokugcina umsebenzi nezindlala sebaceous emzimbeni.

Human umsebenzi adrenal e lithathelwe omzimba izimo ezicindezelayo

Lezi imisebenzi ukuthuthukisa neurotransmitters ethize (epinephrine, norepinephrine) ezithinta ukusebenza of the nozwela isimiso sezinzwa, iqhaza ekufezeni pulses. Ngaleyo ndlela-hormone idatha neqhaza kabusha umzimba ngaphansi kokucindezeleka. Bona ukwandisa izinga inhliziyo nomfutho wegazi, ukwanda ukujuluka, encishisiwe motility pheshana emathunjini, kuvusa bronchodilation.
