Ngezifo Mysterious - heterochromia eye

Heterochromia eye ezinxulumene wokunyhashwa sombala amagama - melanin. Abantu nesi sifo kufuneka umbala eyahlukileyo iris. hormone Melanotropin ethe yaveliswa kwi ingqondo yebhinqa, engena kwemithambo yegazi ulwelo lwe-cerebrospinal, kwanwenwa wonke umzimba, oko elawula biosynthesis-bala lintsundu emzimbeni. Emva koko hormone molecule hydrolases peptide cytocidal. Ngoko ke, xa kwimeko notyeshelo biosynthesis-bala lintsundu melanotropin kwaye kuphuhlisa heterophthalmia. Kufuneka wathi yoxinaniso-bala lintsundu kugqiba umbala yamehlo. iris Umbala kwamehlo zinxulumene kakhulu nombala ulusu kunye neenwele. Kukho iindidi ezimbini eziphambili iris - ukukhanya (ubukhulu becala blue-izimvi nemibala eyahlukeneyo) kunye emdaka (brown emnyama kunye ukukhanya). Kuye kwasekwa ukuba ngokupheleleyo irises efanayo kufuneka uhlobo wabantu ayisekho (okt ukuthengwa okuzikisa kudala).

Heterochromia iliso nawo abangwa lonke ibala. Iingcali abaninzi oyikholelwayo ukuba lonke ibala lokwenene abunjwe ngenxa yeenkqubo sisiba mandundu kwi iris. Into ebalulekileyo kuphuhliso yamehlo heterochromia yi yofuzo. Kulo mzekelo, elinye iliso uya kuba imibala kayise, kwaye eyesibini - nonina.

Musa ukulibala ukuba amehlo heterochromia kuphuhliswa ngenxa iintlobo zezifo ezahlukeneyo (iritis, glaucoma, siderosis choroidal, ukopha, njalo njalo). Ekuqaleni, kulo mzekelo, umahluko umbala iris ithathwa omnye iimpawu zicacileyo. Nangona kunjalo, esi sifo eziphambili ezicaciswe kwisifundo eneenkcukacha.

yahlulwe Heterochromia amehlo ngokwendidi ezintathu: secretory, ngokupheleleyo, engundoqo. Eyona uphawu heterochromia secretory kukuba imibala ezimbini ezisegumbini iris. Xa amehlo heterochromia olupheleleyo imibala eyahlukileyo mntu. Xa heterochromia engundoqo iris uye imibala ngaphezu ezimbini. Ethetha ngazo, omnye ema umbala lubalaseleyo, kusekwe umsesane ngeenxa umfundi.

Ngenxa yophando lwamehlo, kwaye kwaqatshelwa ukuba abantu kwafunyaniswa heterochromia ngeliso, cataract, kunye cyclites ngokufuthi kubhalwe. Heterochromia rhoqo ngokulinganayo waphawula kokubini brunettes ezimnyama-eyed ukukhanya-eyed blonde, yaye. Abanye ababhali bathi ukuba le ngezifo nto nangoku ezivame kakhulu izigulane abanamehlo aluhlaza. Kwezinye iimeko, heterochromia abantu eziphawulwe kwabantwana abaselula, abanye - Izigulane ithole le nto kuphela xa sele umdala. Heterochromia abhalwe rhoqo kwizigulane abaneminyaka eyi-20 ukuya kwezingama-45.

Heterochromia ne umyalezo neurogenic kuzo zonke iimeko sikhatshwe umsebenzi eziqhelekileyo yamehlo eqaqambileyo, ngaphandle naluphi na uhlobo iidipozithi phezu komhlaba inwebu, clouding le vitreous kanye lens. iimviwo engabonakali ibhaqwe nciphisa stromal sombala xi kuthelekiswa namanye iliso. Kulo mzekelo, i nombala iris yi yisiwa kuzo zonke iinxalenye zayo. Olu hlobo luphawulwa phambi heterochromia luvo onovelwano paresis kwicala apho iso le olumbhatshileyo. Uphuhliso heterochromia neurogenic ezinxulumene nokonyuka ucaphuka le ganglion wesibeleko novelwano. Utsho nerve kuchaphazela uphuhliso iris kunye mbala yayo. Ezi nguqu ibonisa ukuba luvuthuluke imasikizi kweli izixhobo ze iinkqubo luvo kunye nemithambo. Esi sifo senzeka kwimfundo kakubi albino kunye ebala mesodermal semehlo. Heterochromia kungalinganiselwanga iliso elinye mesodermal iris ebala. Omnye umahluko albino heterochromia kukuba engaphenduli iingxaki kwaye usapho, ilifa anomaly mbala biosynthesis emzimbeni.
