Diencephalon

Midbrain ke karolo kholo ka ho fetisisa le haholo ka tshebediso bohlokoa tsa bakoang boko. E na le palo e ngata ea cores tse litsi bohlokoa haholo ea tsamaiso autonomic, hammoho le karolo e itseng ea eona e na le litsoelesa ba babeli endocrine - the tšoelesa pineal le pituitary tšoelesa. Midbrain e teng ka haholo polokelo callosum pakeng tsa hemispheres bokong, ho ke ke e fokolang ho ka morao optic pampitšana 'me kamorao perforated ntho,' me ka pele ho tsa - e optic chiasm.

The lipakeng sebopeho ea boko e thata, hobane ke palo e khōlō ea litsi fapaneng hore laola ho ea ka tšebetso e tloaelehileng le tshebetso e nepahetseng ka makala a sa tšoaneng le tsamaiso ea. Bokong (lipakeng) ke hlaheletseng: epithalamus, thalamus, metathalamus, ventricle boraro le hypothalamus.

The thalamus (hillocks bonwang) eaba ba etsa para ea sebopeho o molelele o. Ho Ho thehoa ke ho bokella taba ea bohlooho ka mokgwa wa nuclei (ka mashome a mane), tse arohane ka mokato ea tšoeu tiileng. Epithalamus hlahiswa epiphysis kapa pineal tšoelesa. Epiphysis le ponahalo e tšoana le khoune kalse mohbat le localized fetang midbrain quadrigemina. Ho tswa kantle ho e koahetsoeng ka komiki, ho tloha eo eketsa ka hare doors, partitions arola epiphysis ka a na le dilae.

Metathalamus hlahiswa medial le, ya e le hantle, ho lateral geniculate 'mele, e leng litsi tsa utloa le Pono. Ba leng teng ka mor'a cushion le likarolo tse peli tsa thalamus le tse amanang le midbrain maoto colliculus phahameng 'me ka tlaase. The hypothalamus e hlahisa funnel, e chiasm optic, ea bohlooho leralleng, pituitary le 'mele e' meli mastoid. The pituitary tšoelesa e bohareng endocrine tsamaiso, teng ka pituitary fossa Sella ka sphenoid. The hypothalamus hlahisa toba karolong e ka tlaase ea diencephalon ena.

All khubung hypothalamic, moo ho pota mashome a mane tsa sebakeng lona ka ho eketsehileng arotsoe ka morao, lipakeng le ka pele, boholo ba bona ba ho hlahisa neurosecretion. Front khubung emeloang paraventikulyarnymi le supraoptic, morao - nuclei hypothalamic le mastoid mele, mahareng - tlaase le verhnemedialnymi nuclei hypothalamic, nuclei le serobugornymi funnel.

Diencephalon boetse e na le ventricle boraro, e leng boko cavity. O tlalehiloe ho ea botlaaseng ba e bone ventricle, pele le ka morao - ka foramen interventricular - the ventricles pele le la bobeli. Joalokaha eka ke ka tsohle tse ling, ke ka akira theo gun boraro vascular, e hlahisa mokelikeli cerebrospinal.

Ho sebetsa ha e boko lipakeng itšetlehile ka likarolo tsa lona:

• The molao oa tsamaiso ea tsamaiso ea endocrine, kaha diencephalon ba ile ba lokisetsa pituitary le pineal. Pituitary hormona di hlohleletsago tlhahiso ea tse latelang: kgolo ya, prolactin (eaba ba etsa bokhoni ba lebese ka alveoli tsa litsoelesa le mammary), TSH, ACTH, follicle-hlasimollang, luteinizing, lyuteotropnogo, 图片 melanotropin, oxytocin, vasopressin. Neurosecretory mosebetsi oa tšoelesa pineal ke hlakile diurnal mokgwa wa. Bosiu synthesizes melatoksin, e amehang ka phapanyetsano pigment, 'me thapama - serotoksin.
• The molao oa tsamaiso ea tsamaiso autonomic. Ka hypothalamus le, teng litsi subcortical tsa reflexes autonomic, tse kang lenyora, tlala, satiety, monyaka, se thabe, thermoregulation, hammoho le mefuta eohle ea maikutlo.
• The lateral geniculate mele teng litsi subcortical ea pono, 'me ka medial le - e utloang.
• The thalamus ke setsi sa nahanela ka kakaretso, ntle olfactory ena.

Midbrain, e le busa, e na le makgetha a ho ba bangata ba tlōla bonyane e mong oa bona a ka ba le liphello tse irreparable, e neng e tla hona joang kapa joang lebisa bokooa kapa lefu.
