Ko’rish analizatori — odam va hayvonlarda ko’rish ta’sirotlari va ax- bortlarni qabul qilib, idrok etadigan va taqlil qilib beradigan murakkab ney- roroseptor sistema; asosiy analizator- lardgt biri. K.a. 3 qismdan iborat: re- tseptor yoki periferik, o’tkazuvchi yo’llar va ko’rish markazi yoki Markaziy qism. K.a.ning birinchi qismi to’r pardada joylashgan. Inson ko’zi 380 dan 760 nm gacha bo’lgan uzunlikdagi yorug’lik nur- larini qabul qiladi. Ko’zga to’shayotgan yorug’lik nurlari shox pardada si-Vadi, qorachiq orqali o’tib, gavharda si- nib, shishasimon tanadan o’tib to’r pardada joylashgan kolbachasimon va tayoqchasimon hujayralarga ta’sir eta- Di. Bu hujayralarda yorug’lik energiyasi nerv qo’zg’alishi \u2014 impulsga aylanib, multipolyar va ganglioz hujayralarga, nerv tolalariga etib boradi. O’tkazuvchi yo’llar esa to’r pardadan boshlanib, ko’rish nervi, xiazma, ko’rish trakti va bosh miya po’stloq osti markazidan ibo- rat. U erdan Markaziy neyron boshla- nib, ko’rish yo’llari bosh miyaning ensa bo’lagidagi po’stloq qismi \u2014 K.a.ning markaziga etib boradi va shu joyda ko’rish sodir bo’ladi. K.a.ning faoliyati Markaziy nerv sistemasining nazorati ostida boshqariladi.<\/p>\n","protected":false},"excerpt":{"rendered":"
