Isakhiwo zangaphandle angaphakathi isikhonkwane

Izikhonkwane ke ukubunjwa horny. Bona phakathi ezihlobene eluswini, abe isakhiwo lamellar aze enze umsebenzi olukhuselayo. isakhiwo zangaphandle angaphakathi isikhonkwane yabangela iipropati zabo ezizodwa. Nail - umaleko necrotic zenziwe ngekeratini, kuyimfuneko ukuze sithantamise ekupheleni iminwe bangabi phantsi koxinzelelo mechanical enzima.

Inxalenye isikhonkwane - eli laphu, apho iqala kuthiwa matrix ukukhula. Oku kuyinxalenye umnwe, leyo esahlula isikhumba isikhonkwane nembasa. Ukuba eli candelo yonakele, izikhonkwane obungalinganiyo, kunye wazivalela - impembelelo encinci. Nail iqala isikhonkwane ingcambu. Le ibekwe phantsi kwesikhumba. Ingcambu isizalo kwaye ikhuselwe kwiimpembelelo angaphandle ngenxa isondo isikhonkwane. Bona aziwa ngabantu abaninzi Ulobuza. Ngentla ivalile Lupula ekukhonzeni uhlobo ukuqhubekeka isizalo. Emva kokukhutshwa isikhonkwane for Lupul, inkqubo Ukuqinisa, nangoku akayeki. Abantu abaninzi ukubuza isizathu sokuba amanxeba onke. Kakhulu nje, kungenxa yokuba isikhonkwane sele ibekwe phezu eluswini, kodwa ihlala ibakala ukubunjwa ngokulula phantsi kuyo nayiphi na impembelelo, kwaye ngokufanelekileyo waguqa. inkqubo Uxinaniso iqala isikhonkwane imbasa kwi isizalo ngokuthi ngokuveza kerotinotsitov.

iimpawu zangaphandle isakhiwo nail sabaqalayo. Isikhonkwane plate nombala cornification ezipinki, engaphandle Lupula. umandlalo Nail ukwathutha igazi evela molekyuli emoyeni, enika ubukho nombala ube bomvu. Le nkqubo ngenxa yenani elikhulu ngcanjana. Kutila ngci ivale ukufikelela umoya nokufuma ukuya isikhonkwane nembasa. Oku kuqinisekisa iimeko elilelona yokwakhiwa kwayo. Yeenzipho ipleyiti singqongwe le izileyi: angasemva kunye icala.

Interior features of ubume uzipho eyahlukileyo kakhulu ukusuka yangaphandle. izinto ezibalulekileyo ezivelileyo bone yokuhlasela kunye derma, efanelekileyo nail ipleyiti kunye ingcambu yawo, kunye matrix gipohiny, kwakunye cuticles umkhala kunye, sise ngasemva. Roller kuba itywina ulusu kwindawo apho isikhumba ebegqwese similise okwaloo nembasa. Kwaba khona ukuba zibe sinuses. Ububanzi isikhonkwane kudla kuyahlukana kuluhlu ukusuka milimitha 0.3 ukuya 0,45. Xa Isalathisi ayafika ububanzi 0.5 - 0.6 eemilimitha, oku kubonisa sifo, njengoko hyperkeratosis.

Ubume ulusu apho isikhonkwane iquka, iyahluka kakhulu emzimbeni komuntu. Okokuqala, kwi isikhonkwane plate ongekhoyo ngokupheleleyo ngamanqatha umaleko. Endaweni dermis papillary luphawulwa luphuhliso olunzulu. Ngayo, kukho ukusekwa striae emikhulu. Net dermis collagen lungu enza indima kumatshini lokubopha isikhonkwane. Ezi iintambo zenza isakhiwo esisiseko isikhonkwane, oko kukuthi imilo yayo. Ngasentla maleko papillary na intsholongwane epithelium, isabelo ngasemva eyaziwa njenge matrix. Abanye abaphengululi baye wayekhondoza ukuba umaleko le epithelium ebhedini isikhonkwane lisebenza njengenxalenye isizalo, okanye mandithi ukuqhubeka kwalo. Awuphathe ihlume inxenye lisisiseko apho iqhele isikhonkwane. maleko Top - isikhonkwane nembasa. Kuba yinqobo yobukho lamanqanaba eziphakathi efana spike, kunye granular kunye nobuhlakani. Lwangaphandle kunye nesakhiwo lwangaphakathi isikhonkwane kunye neempawu zayo ezizodwa ziye zabangela ukuyilwa isikhonkwane nembasa. Ukuba inkqubo igqojozwe (sigaba ubuncinane omnye ukukhula kunye ukuyilwa ipleyiti), oko kungadala isifo isikhonkwane.
