Turkish sehhashi ubuchopho: izindima ukusebenza umzimba womuntu, zokugula futhi uphethwe

Sella isakhiwo yokwakheka iseningizimu ngasesinqeni se ugebhezi lwakhe ecaleni ingqondo lapho ibekwe main endocrine indlala, futhi yibona ababaluleke kakhulu kulo isiqondiso humoral imisebenzi umzimba. Ikhipha Turkish ubuchopho sehhashi kanje: ke itholakala the sphenoid ikhefu ne emuva, ezinhlangothini okuyizinto iziteshi ezimbili we emsipheni optic futhi optic chiasm ine phezu phambi kobuso. Nangu venosus itheku, bese ufaka ingaphakathi cranial ezimbili yangaphakathi carotid lemithambo akha main lwemithambo kwegazi ama- pool.

idatha yokwakheka

Turkish ubuchopho esihlalweni ngokufanele ngezansi le ngxenye, ingxenye ephakathi kwesakhiwo, okuyinto synthesizes futhi statin liberiny, amangqamuzana omoya peptide badlulisela isignali kuya pituitary bangazihluphi sonke isikhala ngenhla ekhosombeni. Ngakho ezivezwa pituitary i-hormone ihlukaniswe ezintathu ingxenyenamba, okuyinto zingafani imvelaphi ngesikhathi ontogeny. I share wokuqala ubizwa ngokuthi neurohypophysis futhi kungenxa nerve izicubu. It amaseli pituitary synthesize hormone ezibalulekile ukuze exchange of amanzi nokunakekelwa umsebenzi contractile we myometrium ngesikhathi sokubeletha bese Amapayipi we nezindlala mammary ngesikhathi lactation. Lokhu vasopressin futhi oxytocin ngokulandelana.

Ingxenyana lesibili adenohypophysis elawula zamagama ezinye hormone ekhiqizwa yindlala okuthiwa i endocrine, sithonye ngqo kubo hormone utho. Ngakho adenohypophysis "ithola" uphawu ngu statin hypothalamic ezivimbela ukukhethwa tropine futhi liberinov. Kuyaphawuleka ukuthi Turkish sehhashi ingqondo isikhathi esiningi elalihlala izakhi ezimbili isakhi wendlala yabesilisa, ngoba njengoba isabelo sesithathu sona sincane kakhulu ukwedlula abanye, nakuba isisindo ingqikithi we pituitary elisungulwe abadala ngezinye mg 500. Ingxenyana yesithathu Lesisemkhatsini indlala isakhiwo kokuba maqondana ngqo adenohypophysis, kodwa ehlanganisa uhlobo oluhlukile amaseli Kuhlanganisa melanocyte inkanuko-hormone okuthiwa i-melanin ekuthuthukiseni zamagama kumaseli ethile epidermis isikhumba.

Isici luba kakhulu ekuthuthukeni ukuntula pituitary-hormone okuthiwa i

A Eqinisweni esiphawulekayo isakhiwo indlala pituitary kanye nolwelwesi kobuchopho nokuba khona-Turkish sehhashi diaphragm, empeleni ehlukanisa phakathi nawo-ubuchopho hypothalamus we ndlala. Kuyinto ngokuvamile kakhulu lokhu sakhiwo ampofu. Leli qiniso Kumiswa usosayensi nge nesibongo Busch ngo-1951, esichaza anomaly ka ezingenalutho sella syndrome. Lokhu kwakha ezingenalutho sella syndrome yisimo isici causative e ukuthuthukiswa lonke iqembu neuroendocrine kwezinso.

izinyathelo zokuxilonga

Turkish sehhashi ubuchopho ngenxa izici kwesakhiwo akuzona amenable ukuba izindlela zesintu zocwaningo, ngoba ngeso okuqukethwe aphethwe izindlela ngemisebe MRI izindawo. -X-ray ukuhlola - lena indlela engcono kakhulu ukuba aqaphele substrate morphological isifo pituitary. Kuhlanganisa kokubili scan CT kanye-X-ray sella. Indlela yokuqala lihlotshaniswa okusezingeni eliphezulu umthwalo emisebeni, kodwa ulwazi kakhulu, njengoba kunikeza ithuba ukuhlola ubuchopho isakhiwo egqinsiwe futhi ngokukhethekile wendlala. Radiography futhi inikeza 2 summation isithombe ohlangothini futhi frontal projection. Futhi indlela kakhulu ulwazi ka-MRI, which ukuba CT ngokuya ukunemba, kodwa ayiwadaluli nesineke emisebeni ukuchayeka. Ngakho, kungenzeka ukuthi lezi zindlela ukuxilongwa pituitary isifo zokugula yaqinisekiswa esihlalweni diaphragm futhi khona izinguquko neoplastic kule ndlala.
