Pituitary Gland: he aha ia a he aha ia no

Anter

• No ke aha ia

ʻO ka pituitary gland, ʻo ia ka pituitary gland i ʻike ʻia, he gland ia i loko o ka lolo nona ke kuleana no ka hana ʻana i kekahi mau hormones e ʻae a mālama i ka hana kūpono o ka meaola.

Hoʻopili ʻia ka hana o ka pituitary gland e ka hypothalamus, kahi ʻāpana o ka lolo nona ke kuleana no ka ʻike ʻana i ka pono o ka meaola a me ka hoʻouna ʻana i ka ʻike i ka pituitary i mea e hoʻoponopono ʻia ai nā hana o ke kino. No laila, hana ka pituitary i nā hana i loko o ke kino, e like me ka rula o ka metabolism, ka ulu ʻana, ka pōʻai menstrual, ka hana ʻana o nā hua a me ka sperm a me nā corticosteroids maoli.

No ke aha ia

ʻO ka pituitary gland ke kuleana no nā hana like ʻole o ke kino, e like me ka metabolism, menstruation, ka ulu a me ka hana ʻana o ka waiū i nā umauma, no ka laʻana. Hana ʻia kēia mau hana mai ka hana ʻana o kekahi mau hormones, ʻo nā mea nui:

• GH, ʻo ia hoʻi ka hormone ulu, ʻo ia ke kuleana no ka ulu ʻana o nā keiki a me nā ʻōpio a hana nui pū kekahi i ka metabolism. ʻO ka hoʻonui ʻia o ka hana GH i hopena i gigantism a me ka emi o kāna hana ʻana, dwarfism. E aʻo hou e pili ana i ka ulu ʻana o ka hormone;
• KANAWAI, i kapa ʻia hoʻi he hormone adrenocorticotrophic a i ʻole corticotrophin, ʻoiai hana ʻia ia i loko o nā adrenal glands, ma lalo o ka mana o ka pituitary gland, a alakaʻi i ka hana ʻana o cortisol, kahi hone e kuleana ai no ka kaohi ʻana i ka pane o ke koʻikoʻi a me ka hōʻoia ʻana i ka hoʻoliʻiliʻi physiological o ka meaola i nā hanana like ʻole. E ʻike i ka wā e nui a liʻiliʻi paha ka hana ʻana o ACTH;
• Oxytocin, ʻo ia ka hōmona ke kuleana no ka hoʻoliʻiliʻi uterine i ka manawa o ka lawe ʻana a no ka hoʻoulu ʻana i ka hana waiū, me ka hoʻoliʻiliʻi i ka manaʻo kaumaha a me ka hakakā ʻana i ka hopohopo a me ke kaumaha. ʻIke i nā hopena nui o ka oxytocin i ke kino;
• TSH, ʻo ia hoʻi ka hormonone stimulate, no ka mea he kuleana ia no ka hoʻoulu ʻana i ka thyroid e hana i nā T3 a me nā T4 hormones, he mea nui ia no ka hana pono ʻana o ka metabolism. E aʻo hou aʻe e pili ana iā TSH;
• FSH a LH, ʻike ʻia e like me ka follicle stimulate hormone a me ka luteinizing hormone i kēlā me kēia. Hana pololei kēia mau hormoni ma ka hoʻoulu ʻana i ka hana o nā homone wahine a me nā kāne, i ka hoʻohui ʻana i ka hana a me ke oʻo ʻana o ka sperm i loko o nā kāne a me nā hua i nā wahine.

Hiki ke ʻike ʻia nā ʻōuli o ka hana hewa ʻole o ka pituitary gland ma o nā ʻōuli i kū aʻe e like me ka hōmona i hoʻonui a hoʻemi ʻia paha kāna hana. Inā he loli e pili ana i ka hana a me ka hoʻokuʻu ʻana o GH, no ka laʻana, ʻike ʻia paha ka ulu nui ʻana o ke keiki, i kapa ʻia he gigantism, a i ʻole nele i ka ulu ʻana, e kū nei ma muli o ka hōʻemi o ka huna ʻana o kēia hormone. ʻike ʻia ʻo dwarfism.

ʻO ka hōʻemi a me ka ʻole o ka hana ʻana o kekahi mau hormones i kauoha ʻia e ka pituitary hiki ke alakaʻi i kahi hanana i kapa ʻia ʻo panhipopituitarismo, kahi e hoʻopili ʻia ai nā hana he nui o ke kino, a pono i ke kanaka e hana i ka hormonal i ke ola no ka mālama ʻana i kā lākou mau hana. E aʻo pehea e ʻike ai i ka panhipopituitarism a me nā ʻōuli nui.
