Pamabhuku chinooneka analyzer

Visual Analyzer - kupfuura kunzwisisa anokunyengedzera gadziriro omumwe havachaoni zvinhu. The runako yose nyika, ayo mhirizhonga mavara uye ruvara rinoreva munhu anogona kunzwa kuburikidza nomuviri uropi uye pakarepo kugona kuunganidza chekubuda kutarisana chiedza ruzivo, uye nokukurumidza ongorora navo. Visual Analyzer munhu - ndiro kuona gwara, kuburikidza icho anopinda uropi kuona mashoko ose. Kunoitawo kuti kubatanidza pajira riya ziso ganda kuti uropi zvivako, akatendeuka vave nhengo zvachose mashandiro.

The nemamiriro kutarisana analyzer

The optic nzira, sezvataurwa pamusoro apa, inotanga peripheral Tutsinga tunofambisa mashoko utwu izvo riri siyana akaturikidzana pamusoro the retina womunhu ziso. Kubva masero aya neuronal uri mutete chaizvo uye pfava fibers, kana axons, izvo zvisina kuvhiringidzwa nokurebesa kune inonzi womukati Kamudzira lateral geniculate muviri. axons izvi vasiri uropi voga uye imwe hondo, izvo chinomirirwa optic etsinga yeziso nerimwe. Sechikamu nechimwe chezvinhu optic etsinga, kana n. opticus, pane tsinga fibers vanenge miriyoni imwe. Vose ndihungu zvizere nhamba nhengo paminda the retina Kanotokonya. Izvi zvinoratidza kuti kutarisana analyzer anokwanisa kunzwisisa zvinodiwa kubva chero pakona the retina apo photoreceptors dziri.

Sam n.opticus topographically akakamurwa zvina zvikuru anatomical mapoka:

- vnutrigaznoy kana intraocularis,

- intraorbital kana interorbitalis,

- intraosseous (vnutrikanaltsevoy) kana intercostalis,

- intracranial kana intercranialis.

Kupesana kwakadaro kunokosha chaizvo kuziva kudzidzira ophthalmologists, nekuti zvichaita aivabatsira kuti idzidziso avo akarurama nechirwere uye Kufembera kuona basa iri sei varwere mune ramangwana. Visual Analyzer wakananga chokuti chete ine kuyambuka akaoma tsinga fibers anonzi "chiasm". Musimboti chiasm ichi ndechokuti fibers kuti zvakaitika optic etsinga, chiasm iri pakutanga kuitawo zvokuti pashure paro optic turakiti ndivo faibha sezvo rworudyi hafu ziso nokuruboshwe.

Zvisinei, mune ichi kunyanya, iro rine kuona analyzer pasina mugumo. Pashure optic tsinga chiasm fibers maviri vakawana sezvataurwa pamusoro apa, rimwe zita - optic turakiti. Kodzero optic turakiti vari neperekreshchennymi axonal pezvakaitwa rworudyi rwepanyama hafu the retina rwerudyi yeziso uye akayambuka fibers kubva medial, kureva mhuno, rworuboshwe hafu the retina yeziso. Nokudaro, muna turakiti kuruboshwe inogona kuchengetwa zvinosanganisira neperekreshchennymi tsinga fibers kubva lateral hafu the retina pakati yeziso kuruboshwe uye akayambuka axonal pezvakaitwa medial hafu rworudyi yeziso the retina. Uye kuruboshwe nezvakarurama optic turakiti inotumirwa subcortical nzvimbo, basa kutarisana manyawi. Unorema kubva faibha chinoguma mune lateral geniculate miviri. Kubva izvi anatomical pfungwa zvivako anomunzwira neurites, izvo zvinoumba danda Grazioli. danda ichi, kana vanopenya apedzerana ari occipital akafukidza, zviri zvakananga kuona munda. Mavari, sezvo masayendisiti anodavira, uye kune muitiro yose kuona zvinhu kugadzira. Mwero wanda izvi, rinorema basa, yaiva mishoma nezvegumi kana kunyange hundredths chechipiri. Nguva - uye munhu anodzidza uye anonzwisisa nguva ipi 'kuwa' panguva iyoyo ake famba maziso zvishoma. Pamabhuku Manyiminya maitiro uye chinokosha kutsinga dzinouya nhengo, sezvo nhengo nokuona. Kuti chiono rinopa vanhu mukuru chikamu mashoko kupfuura dzimwe pfungwa nenyere.
