Diencephalon

Midbrain Ko te wahi nui, me te tino functionally nui o te kakau roro. Oku i ai e he maha nui o otaota e he pokapū tino nui o te pūnaha autonomic, me te he wahi o ngā reira o repe endocrine e rua - te repe pineal me te repe. Kei Midbrain te i te tino io hono i waenganui i te tuakoi kaka, he reira iti ki te muri wahi whatu me te posterior pūwatawata taonga, a mua o - te chiasm whatu.

Ko te takawaenga hanganga o te roro e faingataa, no te mea te mea he maha nui o pokapū rerekē e whakahaere te mahi noa me te mahi tika o ngā whēkau, me ngā pūnaha. I roto i te roro (takawaenga) he taiea: epithalamus, thalamus, metathalamus, toru ana roro me te hypothalamus.

Ko te thalamus (hillocks ataata) hanga he rua o te āhua elongated. Kei te hanga e te reira e te haaputuputuraa o te mea hina i te puka o te karihi (e pā ana ki e wha tekau), e kua wehea e te apa o ma totoka. aroaro Epithalamus epiphysis repe pineal ranei. Epiphysis i roto i te ahua rite i te tihi kauri, me te paetata runga quadrigemina midbrain. Mai i te waho te taupokina ai a reira ki te capsule, i nei whakawhānui roto pātaki wehe epiphysis ki poro.

aroaro Metathalamus medial me, o te akoranga, te tinana geniculate lateral, e ko te pokapū o rongo me te kite. E tū ana i muri i te urunga e rua nga wahi o te thalamus me e hono ki te midbrain waewae colliculus pai, me te raro. aroaro te hypothalamus te kōrere, te chiasm whatu, te puke hina, rapae o me tinana māhunga rua. Te repe ko te pokapū pūnaha endocrine, kei roto i te rapae o fossa Tira runga rahirahinga. hua ïa te hypothalamus te wahi o raro o te diencephalon.

karihi hypothalamic katoa, te wahi atu wehea a tawhio noa e wha tekau o ona wāhi ki te muri, takawaenga me te mua, te nuinga o ratou hua neurosecretion. karihi Mua kanohi paraventikulyarnymi me supraoptic, muri - karihi hypothalamic me te tinana māhunga, reo - raro me verhnemedialnymi te karihi hypothalamic, karihi, me te kōrere serobugornymi.

Kei hoki Diencephalon te toru o nga roro, i te mea te kōhao roro. korerotia e ia i te raro o te ana roro tuawha, mua, me te hoki - i roto i te puta iti interventricular - te ventricles tuatahi, me te tuarua. Ka rite ki ki era atu katoa, he i roto i te toru o nga plexus iaia, e hua inu cerebrospinal.

Ko te mahi o te roro takawaenga tei runga i ona wahi:

• Ko te ture o te pūnaha endocrine, mai i roto i te diencephalon whakaritea rapae o me te pineal. Rapae o taiaki whakaongaonga te hanga o te whai ake: tupu, prolactin (hanga kaha o te waiu i nga alveoli o te repe mammary), TSH, ACTH, ruahuru-whakaongaonga, luteinizing, lyuteotropnogo, melanotropin, oxytocin, vasopressin. mahi Neurosecretory o te repe pineal ko te aratau awatea mārama. Po synthesizes melatoksin, whai wāhi nei i roto i te utu ngarahu, me i roto i te ahiahi - serotoksin.
• Ko te ture o te pūnaha autonomic. I roto i te hypothalamus, Kei pokapū subcortical o reflexes autonomic, pērā i te matewai, matekai, makona, i pai ai, riri, thermoregulation, me te momo katoa o mana'o.
• Kei te tinana geniculate lateral pokapū subcortical o kite, a i roto i te medial - rongo.
• Ko te thalamus Ko te pokapū o te tūtohutanga whānui, anake te olfactory.

Midbrain, rite ki te tikanga, he maha ngā āhuatanga i roto i te ofatiraa o te iti rawa tetahi o ratou kia whai hopearaa tūnguru, e pai te taniwha, arahi ki hauātanga ranei te mate.
