Hypothalamic-pituitary kahua

Hypothalamo-pituitary'ōnaehana mea he mall hui ana morphofunctional pituitary (kaʻina hana o ka lalo appendage o ka lolo) a me ka hypothalamus (kāleka i loko o ka diencephalon) i ka pae'āina ma ka hooponopono ana i autonomic oihana i loko o ka papa kuhikuhiE kino.

Hua mai la i loko o ka 'Oihana diencephalon hormones i ka pololei inhibitory a noho haumāna kahi kanawai ma ka secretion o hormones lalo cerebral appendage. Ma keia hihia o ka hypothalamo-pituitary'ōnaehana a ia mai he kuleana pili i kou manaʻo. Ua Ua manaoia no ka hooponopono o ka hōmona secretion a me ka hoʻololi kemikala (ma ka hoʻoulu i ka? Iecaianoaaiiie o hormones ma endocrine glands ua hoemi secretion o hormones i loko o ka 'Oihana diencephalon). Hypothalamic-pituitary'ōnaehana ikea ai kou manaʻo, e kokua i ka mālama kūpaʻa i loko o ke kino.

Gipofizotropnye hormones diencephalon kāleka māheleʻia i loko o liberiny (ikaika), a me ka statin (ke peleki pāʻana) o ka lakou mau? Iecaianoaaiiie koaʻe ke hormones. Ka palapala pauku hanauna ua hana lolo neuropeptides (ke ano o ke kumuʻiʻo nā lātoma).

Ma ka hapanui o hormones hypophysis hypothalamus noho haumāna kahi manao, i kū'ē i ka prolactin - secretion mea ma lalo o tonic inhibitory keiki hypothalamus.

Inā ke poho (haahaa transection) i loko o ka haʻahaʻa lolo kumu appendage conserved secretion o oxytocin a me ka vasopressin axons i loko o ka Media eminence. Penei, ka mea, aole e hoʻomōhala mimikō insipidus. No kona wehe 'ana o ka hypothalamus a kiʻekiʻe transection o nā wāwae stimulates oxytocin-i? Iecaianoaaiiuo poho, vasopressin, a me nā mea a pau akā, me ka prolactin hōmona i loko o ka pituitary gland.

Ke'ī mai, me ka mana o ka hypothalamic-pituitary kahua.

Physiology kuhi hoʻi pilina ma ka puka o na moku ma ka adenohypophysis. Vascular paia permeabilityʻokoʻa no ka nui nā polokina. Groups i koho aeea nuclei i hana i loko o ka hypothalamus. Iwaena o lakou, he 32 hui. Lakou komo 'ana i loko o ka rula o ka loa nui mana i loko o ke kino. Ma keia wahi i kia i ka-oaio? A kiʻekiʻe o ka kōkua aloha a me ka parasympathetic māhele o ka autonomic ko mākou hopohopo nenoaiu i loko. Pela, ua laweʻia mai ke koko, rula hooponopono, wela, hiamoe, wela? Iecaianoaaiiie, lilo o ka ikaika loa ka makemake, a me nā vascular permeability.

Hypothalamic-pituitary'ōnaehana mea ole i kekahi,ʻaʻole wale nō i loko o ka malama ana i ke kūpaʻa o ka maloko 'ia o ke kanaka. Ua kekahi hoakaka o ka malama, i kela la, naciiiuo, a me nā rhythmic hormonal fluctuations.

HPA (axis) (hypothalamic-pituitary-adrenal (axis)) mea hiki ia i ka nui inhibitory ia ma luna o ka functioning o ka wahine reproductive'ōnaehana ma kekahi mau pae. Hua mai la i lalo o ka aoao o CRH (KTRG - corticotropin-opa hōmona) proopiomelanocortin peptides mana a inhibitory ia ma luna o ka? Iecaianoaaiiie o hypothalamic gonadotropin-opa hōmona. Glucocorticoids inhibit ka? Iecaianoaaiiie o ka LH (luteinizing hōmona) pituitary a me ka progesterone a me estrogen i loko o nā ovaries, haʻahaʻa pā lonoaʻili o kekahi mau nā'aʻaʻa e estradiol.

Pela, ua paa ka manao o ka ki kūlana o ka HPA (axis) ka wā ho okumu i ka stress amenorrhea (ka nele o menstrual manawa i oi aku mamua o 6 mahina), "hypothalamic". A me keia, aia no he pololei stimulatory ia ma estrogen'ōewe ka mea hoʻopaipai (mua iho kaʻina o nā nucleotides), i mea kuleana no ka hoʻololi kemikala KTRG a noradrenergic hale i loko o ka CNS. Kēia wehewehe i ke alo o ka mehana hypercortisolism (mahuahua functionality adrenal cortex), uunu nui, naʻau i loko kāna hana, naʻau i loko nā poʻohiwi o, ikaika loa ka makemake kāna hana a me nā symptoms.
