Iyo metabolism ye epidermis ndeyokuti basal keratinocytes zvishoma nezvishoma inofamba ichikwira kumusoro nekusiyana kwesero, uye pakupedzisira inofa kuti iite isina-nucleated stratum corneum, uye inodonha. Zvinowanzotendwa kuti nekuwedzera kwezera, basal layer uye spinous layer zvinokanganiswa, kuungana kwe epidermis uye dermis kunova flat, uye ukobvu hweepidermis hunoderera. Sechivharo chekunze chemuviri wemunhu, epidermis inosangana zvakananga nekunze kwekunze uye inobatwa nyore nyore nezvinhu zvakasiyana-siyana zvekunze. Epidermal kuchembera kunoratidza zviri nyore pesvedzero yezera uye zvekunze zvinhu pakuchembera kwevanhu.
Mune epidermis yeganda rekuchembera, kusiyanisa kwehukuru, morphology uye kusvibisa zvimiro zvebasal layer masero zvinowedzera, kusangana kwe epidermis uye dermis zvishoma nezvishoma kunova flat, epidermal mbambo inova isina kudzika, uye ukobvu hweepidermis hunoderera. Epidermal ukobvu hunodzikira neinenge 6.4% pamakore gumi, uye inoderera nekukurumidza muvakadzi. Epidermal ukobvu hunoderera nezera. Shanduko iyi inonyanya kutaurwa munzvimbo dzakavhurika, dzinosanganisira nzvimbo dzekunze dzechiso, mutsipa, maoko, nepamberi. Keratinocytes inoshandura chimiro sezvo ganda rinokura, richiva pfupi uye nemafuta, nepo keratinocytes inova yakakura nekuda kwekupfupika kwepidermal turnover, nguva yekuvandudzwa kwekuchembera epidermis inowedzera, basa rekuwedzera kwemasero epidermal rinoderera, uye epidermis inova shoma. kuonda, zvichiita kuti ganda rirege kupera uye kuunyana.
Nekuda kwekuchinja uku kwe morphological, iyo epidermis-dermis junction haina kusimba uye panjodzi yekukuvadzwa kwesimba rekunze. Nhamba ye melanocytes inoderera zvishoma nezvishoma mushure memakore makumi matatu, simba rekuwedzera rinoderera, uye enzymatic basa re melanocytes inoderera pamwero we8% -20% pamakore gumi. Kunyange zvazvo ganda risiri nyore kutsvuka, ma melanocyte anowanzoita kuwanda kwenzvimbo kuumba mavara emavara, kunyanya munzvimbo dzine zuva. Masero eLangerhans akaderedzwawo, zvichiita kuti ganda rekuzvidzivirira ridzikire uye ritapurwe nezvirwere zvinotapukira.
Skin anlayzermuchina unogona kushandiswa kuona kuunyana kweganda rechiso, magadzirirwo, kurasikirwa kwecollagen, uye contour yechiso kubatsira kuona kuchembera kweganda rechiso.
