Le analyzer olubonakalayo unique

Analyzer Visual - inkqubo olunzima kakhulu kwaye ezifihlakeleyo okuqonda izinto ezibonwayo. yonke Ubuhle zehlabathi, uqhushululu yayo imibala kunye ezikhanyayo umbala umntu uyakwazi ukuva ngawo umzimba ingqondo kunye namandla yethutyana ukuqokelela ukuhamba ezibonwayo, ulwazi ukukhanya ngokukhawuleza sihlaziye kubo. Analyzer Visual umntu - na indlela ezibonwayo, ongena ngayo ingqondo yomntu lonke ulwazi ezibonwayo. It ikuvumela ukuba ukwazi ukuqhagamshela umnatha ulusu iliso kwizakhiwo ingqondo, zizenza indlela esebenza ngokusisigxina.

Ubume analyzer olubonakalayo

Indlela optic, njengoko kuchaziwe apha ngasentla, iqala nge-luvo peripheral ezo zifumaneka maleko ezahlukeneyo retina iliso yabantu. Ukusuka kwezi seli neuronal kukho imicu ezibhityileyo kakhulu kwaye aphuke, okanye axons, ezo aziphazamiseki wandise loo nto ibizwa ngokuba yinkqubela-capsule lwangaphakathi umzimba geniculate lateral. Ezi axons azikho ingqondo ayinabantu kwaye uluhlu enye, nto leyo bubonakaliswe luvo optic lweliso nganye. Njengenxalenye nganye ye-luvo optic, okanye n. opticus, kukho luvo malunga nesigidi esinye. Bonke bephela zihambelana ngokupheleleyo kunye nenani lamalungu ingentsimi receptor retina. Oku kubonisa ukuba analyzer olubonakalayo uyakwazi ukubona eyenza ukusuka phantse naluphi ekoneni retina apho zifumaneka iiphotoreceptor.

Sam n.opticus topographically yahlulwe izahlulo ezine ezinkulu yokwakheka:

- vnutrigaznoy okanye intraocularis,

- intraorbital okanye interorbitalis,

- ofaka (vnutrikanaltsevoy) okanye intercostalis,

- intracranial okanye intercranialis.

Loo candelo kubaluleke kakhulu ukwazi abasenkonzweni ophthalmologists, ngokuba uya lula kuqulunqo loxilongo zabo ezichanekileyo uqikelelo umsebenzi olubonakalayo kwizigulane abachaphazelekayo kwixesha elizayo. Analyzer Visual into ethile yi kukuba kuphela ngayo yokunqumla nzima Imisonto-luvo ebizwa ngokuba "chiasm". Undoqo kule chiasm kukuba imicu kwathi luvo optic, chiasm kanye ekuqaleni ukwabelana ngendlela yokuba emva kwayo phecana optic ke ifayibha njengoko Icala lasekunene iliso kwaye nasekhohlo.

Noko ke, kule ethile, eba analyzer olubonakalayo ngaphandle ekupheleni. Emva Umthambo-luvo chiasm Imicu ezimbini ifunyenwe njengoko kukhankanyiwe ngasentla, elinye igama - phecana optic. Etyenenezileyo optic iinkqubo neperekreshchennymi axonal ilungelo isiqingatha nezenyama retina ekunene ukhozo lweliso neerhali bawela ukusuka medial, ukutsho oko, impumlo, isiqingatha lasekhohlo retina yeso. Ngokunjalo, kwisiqwenga ekhohlo inokubonakalisa iquke luvo neperekreshchennymi ukusuka kwisiqingatha zisecaleni retina yeso yasekhohlo kunye awelela neenkqubo axonal isiqingatha medial lweliso lakho retina ekunene. Kwaye ekhohlo nasekunene iphecana optic ithunyelwa kumaziko subcortical, onoxanduva kuyabuya olubonakalayo. Isambuku ifayibha uphela imizimba geniculate lateral. Ukusuka kwezi zakhiwo ingqondo yokwakheka ukwandisa neurites, nto leyo yenze umqadi Grazioli. Le umqadi, okanye kugudiswa unyulu xa lobe Occipital, ezo intsimi ezithile ezibonakalayo. Kuzo, njengoko izazinzulu zikholelwa, kwaye kukho yonke inkqubo yokujongwa izixhobo ezibonwayo. Izinga ezi khemikhali, umsebenzi enzima, kuthetha ukuba ube zizahlulo ezimbalwa okanye hundredths yomzuzwana. Mzuzwana - kwaye umntu efunda yaye uyayiqonda into 'owileyo' ixesha ngelo xesha amehlo akhe ezula kancinci. Le nkqubo kokugcina ezizodwa kunye ilungu ebalulekileyo ezifana yovakalelo, njengoko iziko emehlweni. Loo mbono unika abantu ipesenti enkulu ulwazi ngaphezu naliphi na ilungu lomzimba.
