Thalamus - Ko te thalamus ko ...: whakamāramatanga, hanganga me te mahi

Whanaketanga o Psychiatry me Neurology i roto i ngā āhuatanga hou e taea waho i roto i-hōhonu mohio o te hanganga me ngā mahi o te roro. Te kore te māramatanga o te tukanga tupu i roto i te tinana e kore e taea e tōtika hamani i te mate, me te hoki mai te iwi ki te ora noa. Maumaui i tetahi wā o embryogenesis - abnormalities ira disorders ranei, e tika ana ki te pānga teratogenic o ngā āhuatanga o waho - mata ki te whanaketanga o te māuiuitanga waro me nunu'a tūnguru.

tari nui

Ko te roro - te hanganga matatini o te rauropi. Kei roto te reira ngā āhuatanga. Ko tētahi o nga tari tino nui whakaaro te takawaenga. Kei reira te maha o ngā hononga: te thalamus, hypothalamus, me epithalamus metetalamus. E whakaaro ana te taketake tino e rua tuatahi.

Thalamus: whaiaroaro

māngai tēnei āhuatanga te rite te hanganga hangarite tau waenga. Kei waenganui i te midbrain me uho. Kei o 2 wāhanga Huānga. образование, входящее в лимбическую систему. Thalamus - he mātauranga, wahi o te pūnaha limbic. mahi te reira i te momo o ngā mahi. I roto i te whanaketanga embryonic, whakaaro te huānga kei te nui rawa. Kei te whakaritea te reira i roto i te rohe mārōrō pera-ka karanga, tata ki te pokapū o te roro. Mai i reira ki te uho weu io whakawhānui i ngā tohutohu katoa. Te mata medial hanga he taiepa taha o te toru o nga ana roro.

whatu

часть сложного комплекса. Thalamus - he wāhanga o te huinga matatini. Kei te hanga e te reira o wha nga wahi. Ko ētahi o ēnei: te hypothalamus, epithalamus, predtalamus me te hikumārō thalamus. Ko te rua whakamutunga e ahu i te hanganga takawaenga. Kei o pineal tala, tapatoru me leashes Epithalamus. I roto i tenei rohe e kei karihi whai wāhi i roto i te faaitoitoraa o te kakara. Whanaketanga epithalamus āhua, me te peritalamusa rerekē. I roto i tenei whakaaro, e tukinotia ratou rite hinonga motuhake. включает в себя более 80 ядер. I roto i te whānui, hanganga thalamus ngā neke atu i te 80 karihi.

pū

thalamus roro ngā pūnaha kākaho. Kei te hanga e te reira e te muka myelinated me wehe nga wahi rerekē o te mātauranga. E tautuhi Ētahi atu wāhi ngā rōpū neuronal. Hei tauira, te āhuatanga intralaminar karihi periventricular, me te pera i runga i. Ko te huānga rerekē nui i te thalamic wahi matua.

whakarōpū

Kei ia pokapū tona karihi. ai tenei ratou uara ki te tinana tangata. kawea Whakarōpū o te karihi i roto i runga i to ratou wāhi rānei. Wehewehe i te rōpū e whai ake nei:

1. Mua.
2. Mediodorsal.
3. Rainawaenga.
4. Dorsolateral.
5. Ventrolateral.
6. posteromedial Ventral.
7. Hoki.
8. Intralaminar.

I tua atu, ka wehea te matua kei runga i te takotoranga o te mahi neuronal i runga rānei:

1. Spotting.
2. Mahi tohu tukatuka tūturu.
3. Rongo.
4. Ture toenga.

momo o pokapū

Tohatoha tānga, me karihi feohi nonspecific. ngā te whakamutunga he maha nui o medial me ngā intralaminar. Ka whiwhi te karihi tānga tohu, e muri matapae i roto i ngā wāhi rerekē o te uho. Ēnei ngā hinonga e tuku i te sensations tuatahi (ventral posteromedial, postlateralnoe ventral, geniculate medial me lateral) me ngātere whai wāhi i roto i te roro tuarongo urupare (taha ventral). matua herekore nuinga o nga ngātere whiwhi i te uho. tura ratou ratou hoki ki te whakahaere i te mahi.

huarahi neural

образование, связанное с гиппокампом. Thalamus - he mātauranga e pā ana ki te hippocampus. Ko te pāhekoheko Ko roto i te ara motuhake, i roto i nei e whakatakotoria ki reira, me tinana mammillary. Na roto i te uho thalamus hono hihi thalamocortical. Ano hoki i reira ko te ara i roto i nei tuku mōhiohio te ki waihakihaki, e pa, te pāmahana. E te reira wahi i roto i te ua. Here i reira e rua tari: te ventral me lateral. I runga i te ngātere haere tuatahi o te mamae me te pāmahana, te tuarua - i runga i te pēhanga, me pa.

supply toto

Kei te mahia te reira na roto i te honotanga i te muri, inferolateral, choroidal lateral me waenganui, me te thalamus paramedian, oko matua subthalamic. Ētahi iwi kua kitea Pākatokato kikokiko. Kei te aroaro o te reira i roto i te puka o te uaua Percheron. I roto i tenei take, neke atu tetahi i te kātua muri o te oko kaka. E whakarato ana i te thalamus katoa toto. Ko te tino onge tenei āhuatanga.

mahi

? Thalamus te kawenga mō te aha? Tenei mātauranga e te rota o raruraru. I roto i te whānui, i te thalamus - he ahua o te hub o ngā mōhiohio. Na roto i tupu te reira nama i waenganui i ngā wāhi subcortical. Hei tauira, ia pūnaha Tārewa, i tua atu i olfactory whakamahi karihi thalamic, te fariiraa me te whakawhitihia tohu i roto i hāngai rohe tuatahi. te wahi whatu o te ngātere hou etine hoki e tonoa i roto i te pokapū wehenga lateral, uaki te mōhiohio hāngai i roto i te rängai rohe uho kōpako. He tūranga motuhake no ki te thalamus i te ture o te 'ā'ā, me te moe. Otaota o te pāhekoheko ki kiri, i whai ahua ai iahiko motuhake e pā ana ki te mahara. Ko te mahi me te oaoa regulates hoki te thalamus. Tūkino o tenei hanganga te tikanga arahi ki pōroa. Ko te thalamus te hono ki te hippocampus mahi etahi mahi i runga i te whakahaere mahara. Kei te whakapono te reira e e hono tona rohe ki etahi o nga wāhi mesial-pae tino. Tenei āta ia rātau me te pārōnaki mahara rekollektivnoy. I tua atu, kī reira e whai wāhi te thalamus e i roto i ngā tukanga neural tika mo te ture nekeneke.

pathologies

No te mea kia whakawhanake te patunga syndrome thalamic. puta te reira-iu kotahi tahu (kirika), ka maru ai sensations. Kei te maha haere tahi te reira e te hīrere huru. rohe thalamic më o ischemia taea meinga maumaui rawa nui. Ko ētahi o ēnei, mo te tauira, ngā mutism akinetic, raruraru oculomotor. A, no te kia puta occlusion më o te infarction uaua Percheron.

hanganga reticular Thalamic

I roto i te wāhanga pokapū o te oko ko te tautau o ngā pūtau. whatua e ratou he maha nui o muka whakawhānui i roto i ngā tohutohu katoa. Ki te whakaaro tatou i tenei hanganga i raro i te karu whakarahi, rite te whatunga titiro reira. Na reira, i huaina ai i te hanganga reticular. haere muka Neural ki te kirinuku, me te hanga i te ara kore-motuhake. Ki te mau tonu to ratou awhina mahi i roto i ngā wāhanga katoa o te CNS. I raro i te mana o te hanganga e whakarei reflexes. I roto i tenei tautau i reira ko te kōwhiringa o ngā mōhiohio. Ko te wahi overlying Ka whiwhi pārongo hou, me te nui anake. Ko tonu hanganga Active i te taumata tiketike, kia rite haere te reira i roto i nga tohu i receptors katoa.

neurons

whakaatu rātou i te tūtohutanga tiketike ki āpiha pharmacological me hormones. Drugs pērā i "reserpine", "Chlorpromazine", "Serpazil" me etahi atu e taea ki te whakaiti i te mahi o te hanganga. I roto i te neurons taunekeneke Uplink me downlink tohu. Ko nga ngātere i roto i te tohanga tamau i roto i te ara iahiko. Nā ki tenei mahi tonu te. Ia, i roto i te tahuri, he tika ki te mau tonu te āhua o te pūnaha io. I roto i te take o te whakangaromanga o te hanganga, i roto i ngā ona wāhanga o runga, i reira mai te moe hohonu, ahakoa tonu tohu afferent ki tae i roto i te uho i te tahi atu ara.
