Ifasitela emhlabeni. Kutholakale izidumbu ezimbili indoda

Ulwazi ukuhlukahluka emhlabeni neqhaza izinzwa. Amehlo usinikeze amaphesenti ayisishiyagalolunye lonke ulwazi engenayo. Izidumbu zabantu abangu- indoda eduze ngakho ezixhumene nobuchopho, okuyinto abaphathiswe Umsebenzi osemqoka sezinzwa zokuxhumana uhlelo nezwe elingaphandle. Indaba for the ukukhanya-sensitive ungqimba iso iyona izicubu ubuchopho kwemizwa. Izidumbu zabantu abangu- indoda usebenzisa ingxenye neuropathy we analyzer isithombe - photoreceptors. Njengoba umqhubi analyzer ezibukwayo isebenzisa emsipheni optic. Le ndlela yokwenza eziyinkimbinkimbi isebenza Ingcenye ephakathi, okuyinto igxile endaweni ezibukwayo ku Lobe occipital we- cortex cerebral.

Ekhuluma izinhlaka umbono, sivamile ukujamela izakhi ukuthi bangaphandle. Okokuqala, i-pair of izinhlamvu zamehlo (amehlo) nemizimba kokwenza imisebenzi asizayo. Lezi zihlanganisa Isivalo, amashiya, eyelashes, indlala lacrimal nemisipha ocular. Zamabhodlela kukhona esikhumbeni emphethweni, bona kukhawulwe iso kanye umqhewu ivaliwe uma kunesidingo. Uma uyikha phezulu le kwangaphakathi kwekhulu kuyinto ulwelwesi lwamafinyila ukuthi bamehlo ochwepheshe olubizwa ngokuthi conjunctiva. Umsebenzi oyinhloko ekhulwini iyona Lubrication of uketshezi izinyembezi esweni, kanye nokuvikela ebusweni kusukela omiswe namathonya lokukhanda. Ngokuvamile umuntu enza eshaywa kanye nge imizuzwana emihlanu.

Ukuziqhenya iyiphi ubuhle - Eyelashes - zitholakala imiphetho Isivalo, bona ahlelwe imigqa 2-3, inombolo yabo ifinyelela ayisishiyagalombili. Zenza umsebenzi zokuzivikela lesi simemezelo, zixwayisa ukuxhumana iso mucosa izinhlayiya angaphandle. A indima enkulu ekuqinisekiseni ukusebenza evamile iso udlala indlala lacrimal. Itholakala ngaphandle ekhoneni eliphezulu esweni. Nanguya njalo njalo yakha ekhethekile imfihlo - slozu. umthamo wansuku zonke sifinyelela 100 ml. Izinyembezi ngokusebenzisa imbobo nasolacrimal ngokuqhubekayo okushiya phakathi komgodi acinene. izinyembezi amakhemikhali limelela isixazululo 1.5 amaphesenti usawoti ovamile (NaCl), okubandakanya ejenti germicidal (lysozyme). Izinyembezi imisebenzi eminingana. Ngokugeza kobuso inhlamvu yeso, hydration yayo kanye nokuvikelwa kusukela ezinhlayiyeni angaphandle namagciwane ungeze O umsebenzi izidakamizwa umkhiqizo ukungezwani sezinzwa futhi yacindezeleka ngokomzwelo.

Of kwezitho zomzimba ziyahamba njalo. Ukuze lokuhambisa zamehlo ukuhlangabezana imisipha iso. Ngo arsenal of iso womuntu, zikhona imigqa emine kanye pair of imisipha etshekile. ukufakwa yabo kuqinisekisa ukusebenza zokuvumelanisa ze-izimbazo okubonakalayo esweni ngalinye, ukuze bukhomba into, okuyinto kubhekwa.

I inhlamvu yeso kuyinto lens yemvelo eyindilinga kabani ubukhulu ifinyelela ngamasentimitha amabili nengxenye. Wakhe ezintathu-nokukhawulela ulwelwesi. Ngokuthi fibrous yangaphandle (Tunica), isilinganiso wathola igama semithambo kanye negama sangekhatsi photosensitive (-retina).

Kutholakale izidumbu ezimbili man is a indlela eziyinkimbinkimbi yemvelo, okuyinto for ukusebenza evamile zidinga ukwelashwa ngokucophelela. Njengoba nje kwezitho zomzimba kwegazi, amehlo akho ukwenza umsebenzi wawo, ne umehluko eyodwa kuphela ukuthi ukuphumula kancane ubuthongo womuntu, kodwa ukusebenza kwazo hhayi ivalwe, kodwa iba ngaphezulu "eco mode".

Ukuze operation evamile, iso kumele banamathela inhlanzeko umsebenzi ezibukwayo. Lezi zihlanganisa ukuhlukaniswa kwesikhathi ukusebenza ukulayisha kanye nezikhawu ezimfushane iziphazamiso. Isakhiwo umzimba evumela hhayi kuphela ukuba baqeqeshe futhi iphimbo imisipha iso, kodwa futhi ekulinganiseni umsebenzi lens futhi izinqubo emsipheni.

Ukunakekela umbono wabo siqu kuzoqinisekisa ukuthi isikhathi eside uzokwazi ukujabulela ngokugcwele ezihlukahlukene imibala kwezwe elisizungezile.
