Hypothalamus - ukuthi iyini nasekuhlanganeni kwawo nesihloko pituitary iyizingxenye

Hypothalamus - kuyini? Ukuze uqale, kufanele licaciswe ukuthi lokhu syndrome hypothalamic. Ngakho shayela eyinkimbinkimbi izimpawu ukuthi zenzeka lapho kunenkinga ezihlobene le ngxenye. Le ngxenye elawula indlala pituitary esiza ekulawuleni i-adrenal umsebenzi, amasende, yegilo kanye amaqanda. Ngaphezu kwalokho, umnyombo hypothalamus unesibopho ukulawulwa lokushisa komzimba, ngoba imizwa, imisebenzi zokuzala, ukukhiqizwa ubisi, izinqubo yokukhula, ne balance of uketshezi nosawoti emzimbeni, isifiso, ukulala kanye nesisindo.

Isakhiwo diencephalon, elise ezansi i-ventricle lwesithathu abizwa ngokuthi i-hypothalamus. Kuyini lokhu? Kuyinto uhlelo eziyinkimbinkimbi ngokwengeziwe ezihilela nuclei engaphezu kuka amathathu. Hypothalamus Abophe sezinzwa futhi izinhlelo endocrine. Central Izilawuli sezinzwa ibhalansi izinto engena emzimbeni futhi esichithwa izinqubo zokwenana, ukuthi unesibopho ukwakheka indlela ukudla.

Le ngxenye futhi pituitary indlala (Lobe posterior)

Ngo hypothalamus kwemiqondo amaqembu amabili ayinhloko hormone ahlobene ne-ukusebenza pituitary front futhi bakhulise. Lapha kukhiqizwa peptides ezintathu ukuthi uthuthe kanye emsipheni Pathways ohlangeni pituitary. Khona-ke zingena nezicubu igodla Lobe posterior isitho. Ukukhululwa lezi peptides bungene egazini - inkinga le ngxenye.

Le ngxenye futhi anterior pituitary

Ukuxhumeka okuqondile ne anterior pituitary indlala kule ngxenye lapho, kodwa lokhu lapho ukukhiqizwa ongaphakeme yamangqamuzana isisindo compounds, okuyinto adluliswa ku Lobe anterior kwamaseli ngokusebenzisa ingosi uhlelo hypothalamic.

Uketshezi of anterior hormone pituitary

Izinto eziyinhloko ezithinta uketshezi hormone we pituitary anterior, iyona indlela yokulawulwa kwezimboni uhlobo ngempendulo nomthethonqubo neuronal. Nerve amaza ngaphandle hypothalamus shintsha noma ngisho ukudlula umthelela kwezinye izindlela zokulawula. Imiphumela efanayo engabanga isifo sengqondo, ngokomzwelo futhi ukucindezeleka ngokomzimba. Futhi kungakwenza ukuthuthukiswa isifo endocrine.

Le ngxenye (kuyini, sesikubonile esiphethweni) kukhipha hormone njalo. Kukhona isigqi ezithile ukukhiqizwa kwama-hormone athile. Uma iphethini yabo siphukile, kungase kukhombise khona izifo ezithile.

Hypothalamus - lokho oyikho asabela ngayo esiqondisweni ukwehla esisindo

Le ngxenye nomusa ukwehla elibukhali isisindo emzimbeni. Uma ulahlekelwa ambalwa amakhilogremu esingaphansi kwesonto, uyozama amazinga ama-hormone ngazo zonke izindlela ukuze sivale lapho sisilela alahlekile. Kungenxa yalesi sizathu ukuthi izazi musa batusa ulahla ngamakhilogremu angaphezu kwamabili ngesonto.

Proper ukwelashwa eziyinkimbinkimbi izinhlobo ukukhuluphala kuzomele sifake nemiphumela hypothalamus, kusukela kanye pituitary indlala, losendzaweni eduze ubuchopho, le ngxenye ukhiqiza olulodwa uhlelo, okuyinto okungukuthi obhekene ukulawulwa omzimba endocrine nezindlala.
