Imisebenzi ye-pituitary gland

I-pituitary gland iyinhloko ye-endocrine ebaluleke kunazo zonke. Itholakala engxenyeni yobuchopho. Kusukela kumthelela wezinto zangaphandle, ivikelwe kusuka nxazonke ngamathambo. I-pituitary gland inemisebenzi ethile, ukukhishwa okulungile okubaluleke kakhulu ekusebenzeni okujwayelekile komzimba.

Imisebenzi emithathu eyinhloko yesikhumba se-pituitary

Eqinisweni, zikhulu kakhulu. Kodwa ngokuyinhloko yamukelwa ukuthatha imisebenzi emithathu kuphela:

1. I-pituitary gland inesibopho sokusebenzisa ukulawula phezu kwezigulane ze-endocrine ezisele: i-gland gland, izigulane ze-adrenal, nezigulane zobulili.
2. Uqondisa imisebenzi yezitho ezihlukahlukene: izinso, isisu, izigulane ezincelisayo.
3. Kungenxa ye-pituitary ukuthi izitho zikhula futhi zivuthiwe.

I-pituitary gland yenza kanjani le misebenzi? Konke kulula: i-iron ikhiqiza ama-hormone akhethekile. Lezi zinsuku ziba nomthelela oqondile kwezinye izitho. Yilokho, empeleni, umsebenzi oyinhloko we-pituitary gland ukukhiqiza ama-hormone.

Amakhomitha we-pituitary gland nemisebenzi yawo

I-Iron ihlukaniswe izingxenye eziningana. Kuzo zonke zazo isethi ethile yezinto zikhiqizwa:

1. I-hormone ye-thyrotropic ilawula ukukhiqizwa kwe-T3 ne-T4 - ama-hormone wegciwane. Futhi, i-responsible for processes and metabolism processes kanye nokusebenza kahle kwezitho zomuthi wamathumbu, isifo senhliziyo, isimiso sezinzwa.
2. Umthethonqubo wesimiso sokuzala - yilokho okwenziwa ama-hormone e-gonadotrophic pituitary.
3. Izinto ze-adrenocorticotropic ziyadingeka ukuze kuhlanganiswe futhi kukhishwe i- cortisol , i-cortisone, ne-corticosterone ekhiqizwa ku-correx e-adrenal.
4. Amahomoni okukhula yi-hormone yokukhula.
5. Ukuze kuvele izimo zasemakhaya , izinqubo zokukhula kwezokushintshanisa , ukujwayeleka kwenqubo yokudla, izinto ze-luteotropic ziphendula.
6. I-Vasopressin , eyenziwa nge-lobe yangemva kwe-pituitary gland, isebenza njengomlawuli wokusebenza okujwayelekile kwezinso, inhliziyo nenqubo yesifo.
7. I-Beta-endorphin ingenye yeziningi zokusebenza. Le hormone isiza ukuxilonga umzimba, kusiza ekunciphiseni ukucindezeleka, kunciphise ithoni yesimiso sezinzwa, uma kunesidingo kunciphisa ukudla.
8. Akukho ukusebenza okuncane ne- oxytocin . Ekuzalweni, ukuqina kwe-contraction ye-uterine kuncike kulo. Uhlinzeka ngokukhiqiza ubisi ngesikhathi sokudla . Futhi kunesibopho sokuvusa ngocansi.

Njengoba ubona, inqwaba yezinqubo ezibalulekile incike kumgogodla ubukhulu bepea enkulu.
