Wapadera zithunzi chowunikira

Zooneka chowunikira - zovuta kwambiri ndiponso zobisika dongosolo la kuzindikira zinthu masomphenya. Kukongola lonse la dziko, chipolowe ake a mitundu ndi mtundu mithunzi munthu amakwanitsa kumva thupi la ubongo ndi mphamvu yomweyo kusonkhanitsa otaya zithunzi, nkhani kuwala ndipo mwamsanga yosanthula iwo. Zooneka chowunikira munthu - ndi njira zithunzi, amene akulowa ubongo wa munthu mudziwe onse zithunzi. Timatha inu kugwirizanitsa mauna khungu maso kuti nyumba ubongo, kuwapatutsa mu limagwirira kalekale ntchito.

Kapangidwe ka chowunikira zithunzi

Njira chamawonedwe, monga momwe tafotokozera pamwambapa, limayamba manyuroni zotumphukira zomwe zili mu zigawo zosiyana za diso la diso la munthu. Ku maselo amenewa okhudza mitsempha ndi woonda kwambiri ndi Chimaona ulusi kapena axons, amene mulibe mawu ndi kuwonjezera kwa otchedwa mkati kapisozi lateral geniculate thupi. axons awa sali a mu ubongo n'kopanda anthu ndipo khamu umodzi, umene umaimiridwa ndi mitsempha chamawonedwe aliyense diso. Monga mbali iliyonse ya mitsempha chamawonedwe, kapena N. opticus, pali za miliyoni mitsempha ulusi. Onsewo ali ndi zogwirizana ndi chiwerengero cha mamembala a minda lilime la diso. Zimenezi zikusonyeza kuti chowunikira zithunzi amatha kudziwa zikhumbo kuchokera pafupifupi ngodya iliyonse ya diso pamene maselowa ali pamtunda.

Sam n.opticus topographically ogaŵikana zinayi magawano lalikulu anatomical:

- vnutrigaznoy kapena intraocularis,

- intraorbital kapena interorbitalis,

- intraosseous (vnutrikanaltsevoy) kapena intercostalis,

- intracranial kapena intercranialis.

Chotero magawano ndi kofunika kwambiri kudziwa ochita ophthalmologists, chifukwa kuti atsogolere chiphunzitso cha matenda awo lolondola ndi ulosi wa ntchito zithunzi odwala anakhudzidwa m'tsogolo. Zooneka chowunikira lachindunji chifukwa chakuti yekha ali ndizi kovuta ulusi mitsempha wotchedwa "chiasm". Akamanena za chiasm izi kuti ulusi kuti pochitika mu mitsempha chamawonedwe, chiasm pachiyambi kwambiri kugawana mu njira yakuti pambuyo kapepala kakuti chamawonedwe ndi CHIKWANGWANI ngati theka lamanja la diso ndi lamanzere.

Komabe, mu iyi, amene ali chowunikira zithunzi wopanda mathero. Pambuyo chamawonedwe mitsempha chiasm ulusi awiri analandira monga tatchulazi, dzina lina - thirakiti chamawonedwe. Thirakiti bwino chamawonedwe ndi neperekreshchennymi axonal njira yoyenera zosatha theka la diso la ufulu mwana wa diso ndi ulusi anawoloka ku medial ndi mwachitsanzo mphuno, theka kumanzere kwa diso la mwana wa m'diso la. Choncho, mu kapepala kumanzere zingaoneke monga neperekreshchennymi mitsempha ulusi pa hafu lateral wa diso wa diso lamanzere, ndipo anawoloka njira axonal medial theka la ufulu mwana wa diso diso. Ndipo lamanzere ndi lamanja thirakiti chamawonedwe zimatumizidwa ku malo subcortical, udindo kutengeka zithunzi. Chochuluka usasungunuke itha lateral matupi geniculate. Kuyambira izi nyumba anatomical ubongo kuwonjezera neurites, zomwe ndi mtengo Grazioli. mtengo uwu, kapena akumaliza chowala mu Lobe occipital, amene ali enieni zithunzi kumunda. Mu iwo, monga asayansi amati, ndipo pali dongosolo lonse processing zithunzi zakuthupi. Mlingo wa motero, ntchito katundu, n'chimodzimodzi ndi magawo angapo kapena ngakhale hundredths a lachiwirilo. Mphindi - ndipo munthu amaphunzira ndipo akumvetsa chimene nthawi kuti "kugwa" Nthawi imeneyo akungoyendayenda maso ake pang'ono. Wapadera dongosolo kuwala ndipo chotero zofunika kwenikweni limba, monga chiwalo cha kuona. masomphenya amene amapatsa anthu kuchuluka wamkulu wa nkhani kuposa wina aliyense tanthauzo limba.
