Tenei analyzer ataata ahurei

Analyzer Visual - te pūnaha tino matatini, me te mohio o te perception o ngā ataata. Ko te ataahua katoa o te ao, e taea ki te ite i roto i te tinana o te roro, me te kaha tonu ki te kohikohi i te rere o ataata, ngā mōhiohio marama, me te hohoro tātari ratou ona ngangau o ngā tae, me te atarangi tae he tangata ko. tangata Analyzer Visual - ko te ara ataata, i roto i nei tomo te roro tangata mōhiohio ataata katoa. āhei te reira ki a koutou te hono i te mata kiri kanohi ki ngā hanganga roro, tahuri ratou ki te tikanga mahi tūturu.

Ko te hanganga o te analyzer ataata

Te ara whatu, rite tuhia i runga ake, haamata ki neurons piringa i e kei i roto i ngā papa rerekē o te etine o te kanohi tangata. Mai i enei pūtau neuronal he muka rawa kikokore, me te pakarukaru, ranei axons, kahore e nei haukotia ka whakawhānui ki te capsule ā-tinana geniculate lateral pera-ka karanga. e kore e enei axons i roto i te roro e taratahi me te ngohi kotahi, fakafofonga'i nei e te faatae te o ia kanohi. Hei wāhanga o ia o te faatae te, n ranei. opticus, i reira e pā ana ki tetahi miriona muka io. E tino hāngai ki te maha o ngā mema o te mara receptor o te etine katoa o ratou. Tenei meka fokotuu e taea ki te kite ponana i tata tetahi kokonga o te etine te wahi e kei nga photoreceptors te analyzer ataata he.

topographically wehea Sam n.opticus ki wha wehenga kikokiko nui:

- vnutrigaznoy intraocularis ranei,

- intraorbital interorbitalis ranei,

- intraosseous (vnutrikanaltsevoy) ranei intercostalis,

- intracranial intercranialis ranei.

Ko te tino nui te wehenga taua ki te mohio mahi ophthalmologists, no te mea ka whakahaere i te reira i te waihanga o ratou tātaritanga tika, me te matapae o te mahi ataata i roto i tūroro pānga i roto i te heke mai. Ko motuhake i te meka e anake te mea he whakawhitinga uaua Visual Analyzer o weu karere i huaina te "chiasm". Ko te ngako o tenei chiasm ko e te muka e haere i roto i te karere whatu, chiasm i roto i te timatanga rawa ki te faaite i roto i te ara taua e i muri i te reira i roto i te wahi whatu ko te muka rite te hawhe matau o te kanohi, me te ki te maui.

Heoi, i roto i tenei ngā, e kua te analyzer ataata kahore mutunga. I muri i chiasm io whatu e rua muka whiwhi rite whakahuatia i runga ake, ingoa tetahi - wahi whatu. Ko te wahi whatu tika e neperekreshchennymi tukanga axonal hawhe matau pae tino o te etine o te tika 'Afio me muka whiti i te medial, arā te ihu, te hawhe maui o te etine o te' Afio. Nä, i roto i te wahi maui taea te kitea ngā muka io neperekreshchennymi i te hawhe lateral o te etine o te 'Afio maui, ka whiti tukanga axonal hawhe medial o te etine Afio tika. Na kua tonoa wahi whatu maui, me te tika ki te pokapū subcortical, kawenga hoki te sensation ataata. Ko te nuinga o te muka mutu i roto i te tinana geniculate lateral. Mai i enei hanganga roro kikokiko whakawhānui neurites, e hanga i te kurupae Grazioli. Tenei kurupae, mutu marama i roto i te taupa kōpako, e he mara ataata motuhake ranei. I roto i a ratou, kia rite ki nga kaiputaiao whakapono, a reira ko te tukanga katoa o te tukatuka rauemi ataata. Ko te tere o enei tauhohe, fatongia taimaha, moni ki te torutoru nga whakatekau ara haurau o te tuarua ranei. Kau - ka haapii te tangata, me te mārama he aha te wa ki "hinga" i taua momeniti ona kanohi e pohehe paku. Tenei pūnaha whatu ahurei me te taua okana tairongo nui, pera te okana o aroaro. homai e kite te iwi i te ōrau nui o ngā mōhiohio atu tetahi atu okana tikanga.
