Lesi sihlaziyi esibukwayo esibukwayo

I-analyzer ebonakalayo iyisimiso esiyinkimbinkimbi kunazo zonke futhi esibucayi bokubona izinto ezibukwayo. Konke ubuhle bezwe obungezungezile, ukuhlukumezeka kwemibala nemibala kungase kubonakale ngumbimbi wombono kanye nekhono elisheshayo lobuchopho ukuqoqa izimpande zolwazi olubukwayo nokukhanya futhi nokuzihlaziya masinyane. I-analyzer ebonakalayo yomuntu yindlela ebonakalayo lapho yonke imininingwane ebonakalayo ingena ebuchosheni bomuntu . Ikuvumela ukuxhuma igobolondo le-reticular yeso ngezinhlaka zobuchopho, ukubenza zibe yindlela eyodwa yokusebenza unomphela.

Isakhiwo se-analyzer ebonakalayo

Indlela ebonakalayo, njengoba kuphawuliwe ngenhla, iqala nge-neurons ye-peripheral esezindaweni ezahlukene ze-retina yesiso lomuntu. Kusukela kulawa maseli we-neuronal kukhona amafayili amancane kakhulu namancane, noma ama-axon, okunga, ngaphandle kokuphazanyiswa, afinyelela kulokho okubizwa ngokuthi umzimba wangaphandle we-capsule wangaphakathi. Lezi zinhlayiya ziya ebuchosheni hhayi ngokwehlukana, kodwa ngezigaba ezilodwa, ezimelelwa yisibindi se-optic saso ngalinye. Ekubunjweni kwe- nertic optic ngayinye , noma n. I-Opticus, kunezimbungulu ezingaba yisigidi esisodwa. Konke kuhambelana ngokugcwele nokwakheka okwenziwe kwamasimu we-receptor of the membrane ebonakalayo. Leli qiniso libonisa ukuthi i-analyzer ebonakalayo iyakwazi ukubona izimpendulo ezivela cishe kunoma iyiphi indawo ye-retina lapho i-photoreceptors etholakala khona.

I-n.opticus ngokwayo ingahle ihlukaniswe ngeminyango emine yemithi ebalulekile:

- intra-gas, noma i-intraocularis,

- intraorbital, noma interorbitalis,

- i-intraosseous (intracavitary), noma i-intercostalis,

- ukungasebenzi, noma i-intercranialis.

Lokhu kuhlukaniswa kubaluleke kakhulu ukwazi osebenza odokotela-ophthalmologists, tk. Lokhu kuzokwenza kube lula ngabo ukuthola isifo sokuxilongwa okufanelekile nokubikezela imisebenzi ebonakalayo kwiziguli ezithintekile esikhathini esizayo. I-analyzer ebonakalayo icacile ngokuthi yiyo kuphela ene-intersection eyinkimbinkimbi yezintambo zezinzwa, okuthiwa "i-chiasma". Okusemqoka kwalesi sihlahla ukuthi izintambo ezidlulayo emgodini we-optic ku-chiasm ziqala ukuhlukanisa ngendlela yokuthi emva kwayo kuleso sibonelo kukhona izintambo, kokubili ukusuka ohlangothini lwesokudla lwamehlo nakwesobunxele.

Noma kunjalo, lesi sici, esinesihlaziyi esibukwayo, asipheli lapho. Ngemva kokuwela lezi zinzwa ezimbili, amafiber athola, njengoba kushiwo ngenhla, igama elihlukile - i-visual tract. Esikhathini esifanele sokubukeka kukhona izinqubo ezingekho ngaphansi kwe-axonal kwesigamu esifanele se-retina se- eyeball yangakwesokudla kanye namafayili ahambile ukusuka kumaphakathi, okungukuthi, isisindo, isigamu se-retina esweni lesobunxele. Ngakho-ke, lokhu okulandelayo kungabonwa ngakwesokunxele: izintambo ezingasetshenziswanga ezivela engxenyeni ye-retina ye-eyeball yesokunxele kanye nezinqubo ze-axonal ezihambayo ezingxenyeni eziphakathi kwe-retina ye-eyeball yangakwesokudla. Kokubili izindlela ezibonakalayo zokunene nezokungakwesokunxele ziqondiswa ezikhungweni ze-subcortical ezibhekene nezinzwa ezibukwayo. Iningi lezintambo ziphela emzimbeni wangaphandle. Kusukela kulezi zindlela ezenzekayo zobuchopho, ama-neurites akha isisindo sikaGrazioles asuka. Le nsimbi, noma ukukhanya, iphela ku-lobe yesipilital, lapho kunezinkambu ezithile ezibukwayo. Kuzo, njengoba ososayensi bakholelwa, futhi kukhona inqubo yonke yokucubungula izinto ezibukwayo. Ijubane lokuphendula okunjalo likhulu kakhulu, elilinganiselwa kumatshumi ayishumi, ngisho nangamakhulu ayisithupha wesibili. Umzuzwana - futhi umuntu uyaqaphela futhi aqonde ukuthi "amehlo akhe aphikisayo" aphethwe kanjani "ukuwa" ngalesi sikhathi. Lona futhi uhlelo oluyingqayizivele lwama-optical of organ such important body as organ of vision. Kuyinto eyenza abantu babe yingxenye enkulu yolwazi kunanoma iyiphi enye ingxenye yomqondo.
