Kua whakaaro koe me pēhea koe e hiakai ai i te wā tika, me pēhea te noho tonu o te pāmahana o tō tinana, me pēhea rānei koe e moe ai i te pō? Kāore ēnei mea katoa e tupu noa mai. Kei muri i ēnei tukanga tino nui o tō tātou tinana he 'rangatira' iti, engari he tino kaha. Ko ia te hypothalamus . I tēnei rā ka kōrero tātou mō tēnei wāhanga o tō tātou tinana he rite te rahi ki te aramona iti, engari he tino mīharo tana mahi.

He aha te hypothalamus?
He repe iti te hypothalamus i roto i tō roro. Koinei te pokapū whakahaere matua o te pūnaha homoni o tō tātou tinana, te pūnaha endocrine rānei. Pērā i te thermostat i roto i tō whare. Pērā i te hauhautanga e tahuri ana ina piki te pāmahana i roto i tō whare, ā, e whakaweto ana ina heke, ka whiwhi te hypothalamus i ngā tohu mai i ngā wāhanga rerekē o te tinana, ā, ka mahi i ngā mea e tika ana hei pupuri i te homeostasis.
Kāore te hypothalamus e mahi takitahi ki tēnei mahi. Ka tohutohu ia i tana kaiawhina matua , arā, te repe pituitary . Ka kiia hoki te repe pituitary ko te 'repe rangatira' nā te mea, e ai ki ngā tohutohu a te hypothalamus, koinei te mea e tuku ana i ngā homoni e hiahiatia ana e ētahi atu repe i roto i te tinana (pērā i te repe tairoiti, ngā repe adrenal, ngā whatukuhu, me ngā whekau whakaputa uri).
Whakaarohia te hypothalamus hei Tumu Whakahaere o tētahi kamupene nui. Ka tohutohu i te repe pituitary (Kaiwhakahaere) ki te mahi. Kātahi ka tohutohu te Kaiwhakahaere i ngā wāhanga kē atu (ngā whekau o te tinana) kia mahi i tēnā.
Te rerekētanga i waenga i te Thalamus me te Hypothalamus
He āhua ōrite ēnei ingoa e rua, nō reira, tera pea ētahi e pōhēhē. He wāhanga o waenganui o te roro ēnei e rua. Engari he rerekē ā rāua mahi.
- Thalamus: Ko tāna mahi he whiwhi tohu mai i ō tātou kare ā-roto (haunga te hongi), te whiriwhiri i ngā mea nui, ka tuku atu ki te roro matua, te wāhanga o te roro e mahi ana i ngā mahi taumata teitei ake. Ka āwhina i ngā mea pēnei i te mahara, te ako, me te aro.
- Hypothalamus : Ko te tikanga o te kupu Kariki "hypo" ko "kei raro." Nō reira, kei raro iho tēnei i te thalamus. E ai ki tā tātou i kōrero ai i mua ake nei, ko tana mahi matua he whakahaere i te pūnaha homoni o te tinana me te pupuri i te taurite o roto i te tinana.
He aha ngā mahi matua o te hypothalamus?
He mahi nui tā te hypothalamus ki te pupuri i te hauora me te taurite o ō tātou tinana. Tirohia tēnei rārangi.
- Te tipu o te tinana me te whakatikatika pūtau
- Te tote me te wai i roto i te tinanaTaurite
- Te whakahaere i te pāmahana tinana
- Te tere o te manawa me te toto toto
- Te tere o te manawa
- Te whakaoho i te hiakai me te matewai
- Te whakahaere i te nakunaku
- Te whakahaere i te moe me te ara ake ( huringa moe )
- te wairua
- Te whakaohooho ā-ira tangata
- Te whakaputa miraka i roto i ngā whaea e whāngai ana i te u
Ngā homoni nui e tukuna ana e te hypothalamus
E rua ngā momo homoni e whakahaerehia ana e te hypothalamus. Ka hangaia ētahi homoni, ka tukuna ki te repe pituitary, ka tukuna atu ki ngā whekau e hiahia ana. E rua atu ngā homoni ka hangaia, ka rongoatia ki te repe pituitary, ā, ka tukuna noa i te wā e tika ana.
| Homoni | He māmā noa iho te mahi. |
|---|---|
| Te homoni tuku-thyrotropin (TRH) | Ka whakaoho i te repe tairoi, ā, ka āwhina i te whakahaere i te pākia o te tinana. |
| Te homoni tuku corticotropin (CRH) | Kua whakahaua ngā repe adrenal kia tukuna te homoni ahotea cortisol . |
| Te homoni tuku-homoni tipu (GHRH) | E whakahaua ana te repe pituitary kia tuku i te homoni tipu, he mea e tika ana mō te tipu o te tinana. |
| Te homoni tuku gonadotropin (GnRH) | Ka whakaoho i te tukunga o ngā homoni (FSH me LH) e tika ana mō te mahi a te pūnaha whakaputa uri me te pakeketanga ā-ira tangata. |
| Dopamine me te Somatostatin | Ko tā ēnei mahi he aukati i te repe pituitary kei tuku i ētahi homoni. Arā, ka hangaia he mana whakahaere. |
| Oxytocin | E kiia ana hoki ko te 'hormone aroha', ā, ka āwhina i te hononga tangata, i te whakahekenga o te kōpū i te wā e whānau ana, me te whāngai ū. |
| Vasopressin | Ka āwhina ki te whakahaere i te mahi a ngā whatukuhu, te pupuri i te taumata wai tika i roto i te tinana, me te whakahaere i te toto totoka. |
He aha ngā tino take o te ngoikore o te mahi hypothalamus?
Ki te kore e mahi pai tētahi wāhanga nui pēnei, ka raru pea te tinana katoa. He maha ngā take e pā ai tēnei.
- Ngā hapa whānau: Ngā whanaketanga rerekē e puta ana i roto i te roro, i te hypothalamus rānei i te wā e tipu ana te pēpi i roto i te kōpū o te whaea.
- Ngā mate ira: Hei tauira, te mate Prader-Willi, te mate Kallmann rānei.
- Whara roro whara: Te pakaru o te roro i puta mai i tētahi aituā.
- Ngā pukupuku roro: Ngā pukupuku e tata ana ki te hypothalamus, e pēhi ana rānei i te hypothalamus.
- Te pokanga roro, te rongoā irahiko, te rongoā matū rānei.
- Ngā mate roro, ngā mate mumura rānei: hei tauira, te sclerosis maha.
- Ngā ngoikoretanga o te kai me te ahotea: Mā ngā mate kai , te nui rawa o te whakakori tinana, te kore e kai i te nui o ngā kaora, me te ahotea hinengaro nui ka nui ake te whakaputanga a te tinana i te homoni cortisol. Ka ngoikore pea te mahi a te hypothalamus.
Ngā mate pea e pā ana ki te hypothalamus
Ka puta pea ngā mate maha nā te ngoikore o te mahi a te hypothalamus.
Te Momona o te Hypothalamic
Ka taea e te kino o te hypothalamus te whakararuraru i te taurite i waenga i te hiakai me te nui o ngā kaora e tahuna ana e te tinana. Ka taea e tēnei te arahi ki ngā tohu pēnei i te hiakai ahakoa te nui o te kai , te piki tere o te taumaha, ngā raruraru moe, me te uaua ki te whakahaere i te pāmahana o te tinana.
Te Amenorrhea Hypothalamic Mahi
He mate tēnei e pā ana ki ngā wāhine. Ina kore te tinana e whiwhi i te pūngao e tika ana (he kai koretake, he nui rawa te whakakori tinana), ina rānei he ahotea nui, ka whakaitihia e te hypothalamus te tukunga o te homoni GnRH. Ka ārai tēnei i te whakaputanga o te hua manu. Nō reira , ka mutu pea te paheketanga mō te neke atu i te 3 marama .
Te Mate Huka Insipidus o te Waenganui
He mate pūnaha ārai mate onge tēnei. I roto i tēnei āhuatanga, ka pakaru te hypothalamus i te pūnaha ārai mate. Ka puta te ngoikore o te homoni vasopressin, e whakahaere ana i ngā taumata wai o te tinana. Nō reira , ka nui te mimi me te matewai nui .
He mea nui: He rerekē rawa tēnei mate, e mōhiotia ana ko te Diabetes Insipidus, i te mate huka mellitus e mōhiotia whānuitia ana e tātou.
Te tātaritanga me te maimoatanga
Mena kei a koe ēnei tohu, ka arotakehia e tō tākuta tō hītori hauora, kātahi ka whakahau i ngā whakamātautau e tika ana i runga i ō tohu.
- Ngā whakamātautau toto me te mimi: hei tirotiro i ngā taumata o ngā homoni (tairoiti, cortisol, homoni ira tangata), ngā taumata konutai, me ētahi atu.
- Ngā matawai roro: Ka taea e te matawai MRI, CT rānei te tirotiro mō tētahi pukupuku, mō tētahi atu kino rānei ki te roro.
- Ngā whakamātautau mara tirohanga
Ko ngā kōwhiringa maimoatanga e whakawhirinaki ana ki te pūtake o te mate me ō tohumate. Kei roto i ēnei:
- Te pokanga, te rongoā irahiko rānei mō ngā pukupuku.
- Te rongoā whakakapinga homoni mō te ngoikore o ngā homoni.
- Ngā whakarerekētanga kai me te āhua noho.
- Te tohutohu hauora hinengaro.
Me mahi noa tetahi o ēnei maimoatanga i raro i te tohutohu a tō tākuta.
Karere Tangohia ki te Kāinga
- He tino 'pokapū whakahaere' te hypothalamus i roto i tō tātou roro e whakahaere ana i te pūnaha homoni o te tinana.
- Mā tēnei wāhanga iti nei e whakahaere tō hiakai, tō matewai, tō moe, tō pāmahana tinana, tō wairua, me te maha atu anō.
- Ka pā pea ngā whara o te mahunga, ngā pukupuku roro, ngā mate pāwera, ngā āhuatanga ira, tae atu ki te ahotea nui me ngā tikanga kai kino ki te mahi a te hypothalamus.
- Ki te pāngia koe e ngā tohu rerekē pēnei i te pikinga ohorere o te taumaha, te mutu o te paheketanga, me te matewai nui, he mea tino nui kia toro atu koe ki tō tākuta tonu mō ētahi tohutohu.
