Pituitary: ndichiyani nanga zotsatira zake pa thupi?

Mmodzi wa ziwalo zikuluzikulu za dongosolo endocrine ndi pituitary England. Kodi izo, ndi sukulu. Ndipotu, mbali imeneyi ya ubongo udindo yopangira mahomoni zimene zimachititsa yokonza ntchito ubereki, kukula, yoyenera kagayidwe mu thupi. Iliyonse, amaika kapena osakwanira chiwerengero mahomoni pituitary umabala, Mulimonsemo imbaendesa munthu ku matenda.

Pituitary England - ndichiyani?

Ntchito yaikulu ya pituitary England - kutulutsa mahomoni wambiri chokwanira pa uyende thupi. Chifukwa lamulo limeneli ikuchitika, ndi kaphatikizidwe wa melanin, gonads timadzi ndi zopangitsa adrenal, chitukuko ndi kuwunika ntchito za malamulo, komanso kukula. Kusiyanitsa kutsogolo, kumbuyo ndi wapakatikati pituitary.

zapambuyo Lobe

Lotentha mahomoni opangidwa mu pituitary zapambuyo, ndi:

• somatotropin, ndi udindo wotere pa kukula;
• adrenocorticotropic timadzi kumene kumakhudza ntchito olondola a adrenal ya;
• thyrotropin - asaaonerera pa ntchito ya chithokomiro England;
• gondatropiny (follikulotropin ndi lyuteotropin) yotithandiza ntchito ya zopangitsa kugonana, lyuteotropin udindo yopanga timafunika ndi androgen, ndi follikulotropin - mapangidwe umuna amuna ndi chitukuko cha follicles mu thumba losunga mazira mu akazi;
• prolactin - mwachindunji nawo mapangidwe mkaka mu mabere, kuti ndi udindo mkaka wa m'mawere.

Chitukuko cha matenda monga dwarfism kapena gigantism, acromegaly, syndrome Cushing ndi, matenda Simmonds-Glinski anachititsa ndi owonjezera kapena akusowa wa timadzi amene ali ndi udindo kwa kupanga ndi pituitary England. Zizindikiro za matenda kumachitika ali aang'ono, ndi wokhwima.

gawo wogwirizira

Mu kachigawo wapakatikati umatulutsa melanocyte zolimbikitsa timadzi. Iwo ali ndi udindo mtundu wa tsitsi, khungu ndi diso. Woyembekezera, mwachitsanzo, nthawi zambiri anati zimakhudzanso amenewa, ngati kunachita mdima wa khungu. Ichi ndi chifukwa kuenjezera melanin, amene ali ndi udindo kwa mapangidwe ndi pituitary England. Kodi ndi chifukwa chiyani pali tsopano bwino.

Koma anthu mzungu ndi tsitsi ofiira omwe "Kodi si n'kudziphatika" Satana, ali ndi jini mutated ndi timadzi cholandilira udindo mtundu.

zapambuyo Lobe

Mahomoni vasopressin ndi oxytocin pamene amapangidwa kumbuyo lobes, amenenso ndi pituitary England. Kodi izo, kodi ntchito zawo? ntchito yaikulu - nawo lamulo la magazi, minofu kamvekedwe, kagayidwe madzi. Iwo ali ndi udindo ntchito ziwalo zoberekera, mitsempha ya magazi, ena ntchito maganizo ndi magazi clotting.

Kuyambira oxytocin pamene yozungulira minofu chidule cha makoma chiberekero, matumbo, ndulu, ndi nawo Kugawilidwa kwanthaka wa ducts mkaka, ili mkati bere.

Udindo wa vasopressin n'kofunika kwambiri komanso. Ndi nthawi ndondomeko ya mkodzo mapangidwe ndi ndondomeko madzi mchere m'thupi. Ngati mwadzidzidzi zimaleka kugwira ntchito, icho chidzakhala kuthandiza munthu chitukuko cha matenda monga matenda a shuga insipidus, amene amagwirizana ndi imfa mkulu wa madzimadzi.
