Kapangidwe ka diso la munthu

Monga odziwika bwino Russian mwambi, "maso -. Kalilole wa moyo" Pa iwo mukhoza kuwerenga khalidwe la munthu. Muonera anthu kuona dziko, onani chinthu chokongola chimene chikuchitika pomwe.

Komanso m'thupi lodabwitsa ili? ndi kapangidwe ka diso chiyani?

Chigawo chapakati cha diso ndi mwana wa diso. Kumakhudzana ndi ubongo makamaka mitsempha chamawonedwe. mwana wa diso kumaoneka ngati chowulungika ndi. Amakhala kutsogolo ndi kumbuyo, mizati amene ogwirizana ndi mzere wolunjika - olamulira kuwala. Kutalika kwa olamulira kuwala munthu wathanzi ndi 24 mm. Diso equator ukugawa diso pawiri, pang'ono wamfupi kusiyana olamulira kuwala. m'litali ndi 23,6 mm. Ofukula mwana wa diso awiri ndi 23,3 mm. Diso lili nembanemba atatu omwe kuteteza ngale asatengere makhalidwe oipa kuchokera kunja. Izi lakunja fibrous chipolopolo, ndi choroid pakati ndi diso lamkati. Corneal-scleral kapisozi ndi ntchito yake zoteteza: izo salola matupi ena kudutsa kwa disolo ndi thupi vitreous. Corneal makulidwe pa malo osiyana zimasiyanasiyana 0,6 mamilimita 1 mm. Mu ntchito yawo kuwala ndi refracting wamphamvu. Diso kapangidwe ndi kuwonjezekeredwa kuti diso lilibe Mitsempha. Koma anaika ambiri molekezera mitsempha. Ndi chifukwa hypersensitivity wa sclera munthu blinks ndi squints pa ngozi pang'ono kwa diso. The sclera diso kuchokera panja makulidwe ndi ku 1 mm., Pamene mbali mkati ndi woonda kwambiri. sine ake zozungulira nthawi outflow wa madzimadzi intraocular.

Kapangidwe ka diso kuwonjezekeredwa kuti yachibadwa diso kuthamanga anakhalabe nthawi zonse. Danga kumbuyo chipinda diso wodzazidwa ndi chinyezi, umenenso kapangidwe kake amuzolengedwa wofanana ndi wa madzimadzi cerebrospinal. ndi zapambuyo chipinda kumbuyo khoma akutumikira monga Iris, ndi kusungidwa pa zomwe mwana. The Iris lili inki udindo mtundu wa maso. Chizindikiro kwa diso mtundu ndi chibadwa opatsirana, ndi mdima diso mtundu ndi khalidwe lenileni poyerekezera ndi kuwala. Komanso mwapadera, ndi chizindikiro lalikulu ndi kupezeka kwa pigment, pamene imvi kapena kuwala maso zofiirira ndi zotheka pa zili otsika pigment. Ngati ochekenera pigment si konse, munthu ali albino. Mitsempha kupereka pinkish yoyera diso. The Iris ali minofu awiri kuti ali ndi udindo kukula kwa mwana wa. Mu kuwala mwana yafupika ndipo mu mdima M'malo mwake, amakhala onse. The ciliary thupi ndi udindo ulimi wa madzimadzi intraocular.

Kapangidwe ka diso kwathunthu mu mawu a sayansi kuwala. Ndi zosadabwitsa kuti chikhalire analenga limagwirira cholinga, buku la anthu akadali osati pansi mphamvu. The diso lili zigawo khumi. Ndi udindo mapangidwe chifanizo ndi maganizo a mitundu ndi mithunzi. Pa diso mmene wathanzi, malingana chiwerengero cha distinguishable mithunzi munthu. Ndipo Rod- ya maselo phirilo zigwirizana mbali zinayi izi: gawo lakunja la constriction, ndi gawo mkati ndi munda synaptic. The timitengo ndi womvera kuwala, chifukwa cha pigment rhodopsin ndi mbewa zakufa iodopsin bwino adani apaulendo. N'zochititsa chidwi kuti ambiri a nyama dziko Kapangidwe ka diso amalola yekha pamaso pa timitengo, koma palibe cones.

Kuphunzira chikhalidwe biophysical ya kapangidwe ndi ntchito ya maso ayenera kuwerenga molumikizana ndi kapangidwe ka maselo ndi mapeto kuti zimafalitsa nkhani ku diso kwa Lobe occipital ubongo mitsempha. Kuchokera m'dera chapakati cha chimbale mitsempha diso kunja Vienna ndi mtsempha wamagazi. fano kudzera mwa diso kumanzere aumbike mwa hafu lamanja la ubongo, ndi fano, atathana diso lake lamanja - kumanzere.

Nkhaniyi imafotokoza Kapangidwe ka diso lili yekha mfundo ambiri. Ngati mukufuna kudziwa kapangidwe mwatsatanetsatane za ziwalo masomphenya ndi mfundo za ntchito zawo, mukhoza kuwerenga akalozera ambiri mabuku pochiza matenda a maso.
