Hypothalamic-rapae o pūnaha

pūnaha Hypothalamo-rapae o ko te rapae o morphofunctional uniana hanganga (tukanga o te taupa o raro o te roro) me hypothalamus (kāri i roto i te diencephalon) e whai wāhi i roto i te ture o ngā mahi autonomic i roto i te tinana matua.

I whakaputahia i roto i te tari diencephalon hormones i te pānga tika inhibitory whakaongaonga ranei i runga i te secretion o hormones taupa raro kaka. I roto i tenei take o te pūnaha hypothalamo-rapae o me te mea he mahi urupare. Ko te tikanga mo te ture o te taiaki secretion me kōtuitanga (na roto i te whakanui ake i te hanga o hormones i roto i repe endocrine iti te secretion o hormones i roto i te diencephalon tari). Hypothalamic-rapae o urupare whakamātautau pūnaha, āwhina ana ki te mau tonu tamau i roto i te tinana.

Gipofizotropnye hormones wehea ki liberiny (whakaū) kāri diencephalon me te statin (braking) o te hanga tēnā hormones Tropic. whakamana te whakatupuranga wāhanga takawaenga te neuropeptides roro (he ahua o ngā rāpoi ngota pūmua).

I roto i te nuinga o hormones hypothalamus hypophysis whakaongaonga pānga, rite te ātete ki te prolactin - he secretion raro toniki hypothalamus mana inhibitory.

Ki te te kino (transection raro) i roto i te raro taupa kakau roro pūmau secretion o oxytocin me vasopressin axons i roto i te hiranga ake waenga. Ko te kupu, e kore e whakawhanake reira mate huka insipidus. Tangohanga o te hypothalamus transection tiketike o nga waewae ranei whakaongaonga oxytocin mate production, vasopressin, me katoa engari te taiaki prolactin i roto i te repe.

Ko te kupu, nga mahi o te pūnaha hypothalamic-rapae o.

Whaiaroaro riro iteraa hononga i roto i oko tomokanga i roto i te adenohypophysis. uruhanga taiepa iaia rerekē mō pūmua nui. Rōpū tīpakohia karihi pūtau e hanga e i roto i te hypothalamus. I roto ia ratou e 32 takirua. whai wāhi ratou i roto i te ture o nga mahi tino nui i roto i te tinana. I roto i tenei rohe kukū te pokapū teitei o nga wehenga pukuaroha me parasympathetic o te pūnaha io autonomic i roto i. Ko te kupu, kawea te pēhanga toto ture i roto, wera, moe, production wera, mate o te hiahia, ka tahi atu uruhanga iaia.

Hypothalamic-rapae o pūnaha he wāhi e kore anake i roto i te tiaki i te tamau o te taiao ā-roto o te tangata. E whakarato ana hoki te marama, o ia rā, kaupeka, me ētahi atu rerekē hormonal naki.

taea ki te whai i te pānga inhibitory nui i runga i te mahi o te pūnaha whakaputa uri wahine i ngā taumata rerekē HPA tuaka (tuaka hypothalamic-rapae o-adrenal) he. I whakaputahia i raro i te mana o CRH (KTRG - taiaki corticotropin-tuku) proopiomelanocortin peptides faaitoito pānga inhibitory i runga i te hanga o hypothalamic taiaki gonadotropin-tuku. Glucocorticoids tautāwhi i te hanga o te LH (luteinizing taiki) rapae o me te taiaki, me te estrogen i roto i nga ovaries, tūtohutanga raro o rerekē te kopa ki te estradiol.

Ko te kupu, whakaritea te tūranga matua o te tuaka HPA te ka hanga i te amenorrhea ahotea (kore o wā paheketanga i roto i neke atu i te 6 marama), "hypothalamic". Te taha ki tenei, i reira ko te pānga stimulatory tika i runga i kaiwhakatairanga estrogen ira (mua raupapa o nucleotides), e te kawenga mō te KTRG kōtuitui me ngā hanganga noradrenergic i roto i te CNS. whakamārama ana tēnei i te aroaro o te hypercortisolism ngawari (nui haere uho taumahinga adrenal), manukanuka, disorders tūāhua, hīrere tūāhua, disorders hiahia me ētahi atu tohu.
