Ntchito za chigoba cha pituitary

Chikopa cha pitupia ndizofunika kwambiri zamtundu wa endocrine. Ili pamunsi pa ubongo. Kuchokera ku zotsatira za zinthu zakunja, zimatetezedwa kumbali zonse ndi mafupa. Mtundu wa pituitary uli ndi ntchito zina, kuperekera kwabwino komwe kuli kofunika kwambiri kuti thupi likhale logwirizana.

Ntchito zitatu zazikuluzikulu za chigoba cha pituitary

Ndipotu, iwo ndi aakulu kwambiri. Koma kwachilendo amavomereza kutenga zitatu zokhazo:

1. Mtundu wa chiwopsezo uli ndi udindo wogwiritsira ntchito mphamvu pazitsulo zotsala za endocrine: chithokomiro, zilonda za adrenal, ndi glands.
2. Amagwirizanitsa ntchito za ziwalo zosiyanasiyana: impso, chiberekero, mazira am'mimba.
3. Ndi chifukwa cha chikhalidwe kuti ziwalo zimakula ndikukula.

Kodi zotupa za pituitary zimachita zotani? Chilichonse chiri chosavuta: chitsulo chimapanga ma hormoni apadera. Zotsatirazi zimakhudza ziwalo zina. Ndipotu, ntchito yaikulu ya mankhwalawa ndi kutulutsa mahomoni.

Mahomoni amtundu wa pituitary ndi ntchito zawo

Iron imagawidwa m'magulu angapo. Pazigawo zonsezi pali zinthu zina zomwe zimapangidwa:

1. Mahomoni a thyrotropic amachititsa kupanga T3 ndi T4 - mahomoni a chithokomiro. Zomwezi zimayambitsa njira zamagetsi ndi ntchito yoyenera ya ziwalo za m'mimba, mtima, mitsempha.
2. Malamulo a kubereka - ndizo zomwe ma hormone a gonadotrophic amachita .
3. Matenda a adrenocorticotropic ndi ofunikira kuti asungidwe ndi kusungidwa kwa cortisol , cortisone, ndi corticosterone yomwe imapangidwa mu adrenal cortex.
4. Mahomoni okula ndi mahomoni owonjezereka.
5. Kwa kuyambika kwa chibadwa cha amayi, kusintha kwa kusinthanitsa, kukula kwa chakudya, luteotropic zinthu zimayankha.
6. Vasopressin , yomwe imatulutsa utoto wa pituitary, imakhala ngati woyang'anira bwino ntchito ya impso, mtima ndi mitsempha.
7. Beta-endorphin ndi imodzi mwa zovuta zambiri. Mahomoniwa amathandiza kuchepetsa kupweteka, amathandiza kuthetsa nkhawa, amachepetsanso kayendedwe kake, ngati n'koyenera kuchepetsa chilakolako.
8. Osagwira ntchito ndi oxytocin . Pa kubadwa, kukula kwa chiberekero cha uterine kumadalira pa izo. Amaperekanso mkaka popanga lactation . Ndipo ndizoyambitsa kugonana.

Monga mukuonera, kuchuluka kwa zinthu zofunika kwambiri kumadalira gland kukula kwa pea yaikulu.
