Ukukhishwa Kwamehlo Kungenzeka Kungenzeka Ngokwemvelo Ngenxa Yokukhiqizwa Kwezinyembezi
Lapho sekufika ekuseni, abantu abaningi baqala usuku ngokugubha amehlo abo. Ngaphakathi komngcele ngamunye, ungabona ukuqoqwa kwezinto ezibizwa ngezinye izikhathi ngokuthi "ukulala" noma "ama-eye boogers". Yini ebangela i-eye boogers? Kungani kungabonakali ukuthi kwenzeke kakhulu emini? Funda ngalokhu kukhishwa kwamehlo nokuthi kungani kuyingxenye evamile nenempilo yokulala.
Isifundo E-Anatomy Ye-Eye
Umngcele weso ngalinye unomkhumbi wesikhumba esibizwa ngokuthi i- epicanthal . Ngalunye uhlangothi lweso libizwa ngegama elihlukile: elilodwa ngempumu yilapho eliphakathi futhi elingaphandle liyi-lateral. Ikholomu le-epicanthal eliphakathi lihlanganisa i-canthus ephakathi kweso. Iqukethe umkhiqizo wemisele yamanzi okuxhuma kwi-tube (noma i-tear traction) ehlanganisa umkhawulo weso kuya emanzini. Lokhu kunemiphumela ebalulekile, futhi kusiza ukuchaza ukuthi kungani izidumbu zigcwala ubuthongo.
Uke waphawula ukuthi ikhala lakho liqala ukugijima uma ulila? Izinyembezi zigeleza zisuka ebusweni bamehlo bese ziqoqa emgwaqeni wezinyembezi ezidlula uketshezi ungene ekhaleni. Nakuba amanye amakhemikhali angase aphule iphuzu lempumlo, eholela ekutheni, enye imfucuza nayo isuswa phansi emqaleni futhi iseswini. Yingakho ungase futhi ukwazi ukunambitha usawoti wezinyembezi zakho ngokukhala.
Izinyembezi zenziwa ngamanzi, amafutha, kanye neprotheyini okuthiwa i- mucin . Basiza ukugcoba ubuso beso futhi bangakuvikela ekutheleleni kwamagciwane nama-bacterium.
Ngesikhathi sokuvuka, ukuchofoza njalo kuhlanza uketshezi nocucuza ohlangana nobuso buso. Cabanga ngobuso bamehlo njengewindi elungile.
Ukuvalwa komunye ijwabu leso kuyakhansela kanye nokucubungula noma yikuphi ukungcola okuvela emvelweni. Uthuli, impova, izifo , kanye nanoma iyiphi enye inhlayiya encane ongacabanga ukuthi ihlanzwa ngokushesha. Njengomshini wokukhwabanisa, amajwabu amehlo ahlanze amafasitela amehlo.
Uma ukungcola okuphawulekayo kufinyelela emehlweni ethu, kuzobangela ukungakhululeki, ukubomvu nokugqwala. Umzimba wethu uyakwazi ukukhipha izinhlayiya ezihlangene naso. Kulo lonke usuku, lokhu kufeziwe. Ama-proteine nezinye izinto nazo zisusiwe. Ngezinye izikhathi singase sesule ngisho nasendlini yamehlo ethu ukusula le nto.
Izinguquko Zamehlo Ekulele
Uma silele, ukungafani okubalulekile kubonakala. Okokuqala, asikho ukukhanya phakathi nobusuku. Ubuso beso bugcinwa ngobumanzi ngamehlo avaliwe. Eqinisweni, izimo ezidambisa ukuvala iso (njengeBell 's Palsy noma isifo) zingabangela ukuma kwamehlo. Ngokuvamile, abantu bangase balele ngamehlo abo ngokuvulekile . Ukuvalwa kwamehlo okuqhubekayo kushintsha izintambo.
Esikhundleni sokuhlanzwa okuqhubekayo kwamehlo, amaprotheni (kanye nalawo amanye ama-debris) awasusiwe. Kungase kube nokukhiqizwa kwezinyembezi ezincane, okuholela ekomeni okwandayo.
Esikhundleni sokuhlanzwa okuqhubekayo, amandla adonsela phansi angasiza ekuqoqweni kwezinto ezingxenyeni ezingezansi zamehlo. Lezizinto zokwakha kanye neminye yamanzi abizwa ngamehlo agxilile emgwaqeni wokuqoqa, njenge-drainpipe. Akuzona zonke izinto ezingasetshenziswa kalula, noma kunjalo.
Izindleko ezinkulu noma izinhlayiya ezincane kakhulu angeke zifakwe emgqeni ongasese. Uma kukhona uketshezi oluncane, i-goop noma i-crud ingase ifake kalula. Lezi zinto zingase ziqokelele ekhoneni lamehlo. Ngenxa yalokho, "ukulala" noma "i-eye booger" ingase iqoqe futhi ifake. Kwamanye abantu, abaningi bangase bathelele.
Kungase futhi kuthinteke ukucinana okungavamile noma amanzi emgodini wezinyosi, njengemithi yokwelapha. Uma i-duct yezinyembezi ivinjelwe , izinkinga zingase zikhule. Ngokuvamile, kungadingeka ukuvula umzila nge tube elixhasayo elibizwa ngokuthi i-stent.
Kuyinto evamile ukuqoqa ama-debris ekhoneni lamehlo ngekhala. Empeleni, kungaba okungavamile uma lokhu kungakaze kwenzeke. Ngaphezu kwalokho, i-epicanthal ipulazi langaphandle lingase liqoqe inani elincane lemfucumfucu. Kungase kuphawulwe ngisho ne-eyelashes.
Iningi labantu lingakwazi ukususa lezi zinsalela ngokusula nje amehlo ekuseni. Uma uzimisele kakhulu, i-washcloth efudumele ingasiza. Abanye bangase bakuthole kudingekile ukusula izinto ezengeziwe ngokusetshenziswa kwamaconsi e-saline iso. Uma uhlakulela ubuhlungu noma ukhulula emehlweni akho, kufanele ukhulume nodokotela njengoba lokhu kungaba uphawu lokutheleleka noma ezinye izinto ezingavamile.
