Nemamiriro womunhu ziso

Sezvo inonyatsozivikanwa Russian chirevo, "maziso -. Girazi mweya" Kwavari iwe unogona kuverenga unhu hwemunhu. Kuburikidza meso vanhu kuona nyika, ona yakaisvonaka chinhu chiri kuitika kumativi.

Sezvo zvakanaka mukati ichi muviri inoshamisa? Chii nemamiriro ziso?

The nechepakati Chikamu ziso chiri yeziso. Zvinonzi kwakabatana uropi kunyanya ari optic etsinga. Yeziso iri yakaita chinhu denderedzwa. Inoitwa mberi uye neshure namatanda, ayo zvakabatanidzwa ne yakarurama mutsetse - the Manyiminya akabatana. Kureba Manyiminya akabatana mune utano munhu 24 mm. Ziso ikweta anokamura yeziso muzvikamu zviviri, pfupi kupfuura Manyiminya akabatana. Its kureba 23.6 mm. Vertical yeziso dhayamita ndiyo 23.3 mm. Yeziso ane membranes matatu kuchengetedza tsanga kubva kunaka nezvinhu kubva kunze. Ndicho wokunze fibrous goko, nepakati choroid uye yomukati the retina. Corneal-scleral Kamudzira ane rwokudzivirira basa: nayo haabvumiri miviri marudzi kupinda kune izvo uye kuti vitreous muviri. Corneal ukobvu kunzvimbo dzakasiyana-siyana zvichisiyana 0,6 mm 1 mm. In zvavo Manyiminya kuita ndiro refracting akasimba. Ziso mamiriro ari vaumbe kuti cornea harina midziyo ropa. Asi vakaisa vakawanda tsinga harinzwi. Zviri nokuda hypersensitivity pamusoro sclera munhu blinks uye squints kuchangotanga ngozi ziso. The sclera ziso kubva kunze ari ukobvu kusvika 1 mm., Apo yomukati divi chitete chaizvo. tenderera sine wave Its anoita water drainage pamusoro intraocular mvura.

The nemamiriro ziso riri vaumbe kuti chakaipa ziso kufurirwa anodzokororwa nguva dzose. Seri cornea kamuri vakazadzwa mwando, izvo, neDare nokukanganisika sezvamunoita akafanana pamusoro cerebrospinal mvura. ari Anterior kamuri veshure rusvingo anoshanda sezvo maziso, uye zvakachengetwa panguva iyo mudzidzi. The Iris rine pigments mhosva ruvara kwemaziso. A chiratidzo ziso ruvara iri majini zvitange, uye rima ziso ruvara chinhu chikuru unhu pachinhu chiedza. More zvakananga, chikuru chiratidzo ndiyo Kuwanikwa ruvara, apo maziso shava pfumbu kana chiedza kunobvira yakaderera zviri ruvara. Kana coloring ruvara haisi zvachose, munhu ane Albino. tsinga ipai pinkish chena ziso. The Iris ane tsandanyama maviri kuti vane basa kukura mboni. In sechiedza mboni ipfupi uye zviri murima, nekusiyana, zvinova vakwanise. The ciliary muviri ndiye anokonzera pagadzirwe intraocular mvura.

The nemamiriro ziso zvakakwana ouzivi Manyiminya wefizikisi. Zvinoshamisa kuti hunhu akaita vachifunga mashandiro, kopi vanhu vachiri kwete pasi simba. The the retina ane gumi akaturikidzana. Hazvina basa paumbwe mufananidzo uye omumwe mavara uye maketeni. On sei noutano the retina, zvichienderana uwandu distinguishable maketeni murume. Uye Rod- pamusoro cône receptors ine zvikamu zvina: rokunze chidimbu, ari constriction, yomukati chidimbu uye synaptic munda. The tsotso vari unetseke chiedza, nemhaka ruvara rhodopsin uye cône pamwe iodopsin nani kubatwa inofamba. Zvinokosha kuziva kuti vakawanda mhuka yenyika nemamiriro ziso achibvumira chete kuvapo tsotso, asi hapana pasikweya.

Kudzidza biophysical hunhu marongerwo uye kushanda kwemaziso inofanira kuverengwa pamwe nemamiriro masero etsinga uye harinzwi kuti nekufambisa mashoko kubva the retina kusvika occipital akafukidza uropi. Kubva nechepakati nzvimbo Disc etsinga ziso kubva Vienna uye tsinga. The mufananidzo pachishandiswa ziso kuruboshwe achiumbwa rworudyi hafu uropi, uye nomufananidzo, yakatarwa ziso rake rokurudyi - kuruboshwe.

Nyaya ino inotsanangura nemamiriro ziso, rine chete zvayo chokwadi. Kana uchida kunzwisisa zvakawanda urongwa ari nhengo wezvakaonekwa uye zvinotaurwa mashandiro avo, unofanira kuverenga dzisingaverengeki Directories uye ophthalmology mabhuku.
