Zenera dziko. Mitembo ya munthu

Chidziwitso cha kuchuluka kwa dziko zimathandiza kuti maganizo. Maso zimatipatsa nainte wa mfundo zonse ukubwera. Matupi a munthu umakhudza ku ubongo, amene ankasamalira Cholinga chachikulu cha mantha dongosolo kulankhulana ndi dzikoli. Nkhani kuunika-tcheru wosanjikiza diso ndi ubongo ubongo minofu. Matupi a munthu pogwiritsa ntchito gawo zotumphukira wa chowunikira fano - maselowa. Pamene wochititsa zithunzi chowunikira amagwiritsa mitsempha chamawonedwe. Izi limagwirira zovuta ntchito pa chigawo chapakati, lomwe lili lolunjika m'dera zithunzi mu Lobe occipital wa kotekisi ubongo.

Ponena za ziwalo masomphenya, nthawi zambiri amaimira zinthu iwo amene ali kunja. Choyamba, awiri eyeballs (maso) ndi matupi pogwira ntchito wothandiza. Zikuphatikizapo zikope, nsidze, nsidze, lacrimal England ndi minofu ocular. The lids ndi khungu makutu, kuchepetsa maso ndi kudula chatsekedwa ngati n'koyenera. Padziko mkati mwa zaka za m'ma ndi mucous nembanemba kuti ophthalmologists akatswiri wotchedwa conjunctiva. Ntchito yaikulu ya atumwi ndi kondomu ya madzimadzi diso misozi, komanso kuteteza nyemba ku kuyanika ndi makhalidwe makina. Bwinobwino munthu achita kuphethira kamodzi pa masekondi asanu.

Kunyada kwa ulemerero iliyonse - nsidze - ili m'mbali mwa zikope, iwo anakonza m'mizere 2-3, chiwerengero chawo ukufika makumi asanu ndi atatu. Iwo amagwira ntchito ndi kuteteza, kuchenjeza kukhudzana ndi diso mucosa particles yachilendo. A mbali yaikulu kuonetsetsa uziyenda yachibadwa diso chimagwira England lacrimal. Malowa ali pamtunda kunja mu ngodya chapamwamba diso. Iye nthawi zonse ndi mosalekeza amapanga wapadera chinsinsi - slozu. Daily buku ukufika 100 ml. Ng'ambani mwa nasolacrimal ritsa mosalekeza bere mu m'mphuno. Mankhwala kuichotsa akuimira 1.5 peresenti njira ya wamba mchere (NaCl), womwenso wothandizila germicidal (lysozyme). Ng'ambani ntchito zingapo. Posambitsa pamwamba pa mwana wa diso, ndi hydration ake ndi kutetezedwa particles ena ndi mabakiteriya anawonjezera O ntchito mankhwala mankhwala mantha mavuto ndiponso maganizo.

Ziwalo anthu zoyenda zonse. Pakuti anasamutsa eyeballs kukumana minofu diso. Mu nkhokwe ya diso la munthu, pali mizere anayi ndi awiri minofu oblique. unsembe wawo amaonetsetsa ntchito synchronous la nkhwangwa zithunzi lililonse diso, kotero kuti iwo converge pa chinthu, amene ankaona.

Diso ndi masoka ozungulira mandala amene awiri ukufika awiri ndi theka masentimita. Atatu-Kuchepetsa Kakhungu. Otchedwa fibrous akunja (tunica), pafupifupi Dzina mtima ndi dzina mkati mwa photosensitive (diso).

Monga ziwalo za magazi anthu, maso ntchito yawo ndi kusiyana kumodzi kokha kuti atenge nthawi yokwanira yopuma mokwanira anthu, koma ntchito zawo si itatha, koma umakhala "Eco mode".

Ntchito bwinobwino, diso ayenera mosamalitsa kutsatira ukhondo wa ntchito zithunzi. Zikuphatikizapo kulekana kwa ntchito nthawi kutsegula ndi nthawi yochepa zosokoneza. Zovuta zokambirana kuti amalola osati wophunzitsa ndi mawu minofu ya diso, komanso ziziyenda disolo ntchito ndi njira mitsempha.

Kusamalira masomphenya awo adzaonetsetsa kuti ndinu nthawi yaitali adzatha kusangalala nawo zosiyanasiyana mitundu ya m'dzikoli.
