Liphetoho tsa sebopeho sa Epidermal le biochemical botsofaling ba letlalo

Metabolism ea epidermis ke hore basal keratinocyte butle-butle e nyolohela holimo ka phapang ea lisele, 'me qetellong ea shoa ho theha stratum corneum e se nang nucleated, ebe e oa. Ka kakaretso ho lumeloa hore ka ho eketseha ha lilemo, lesela la basal le lesela la spinous lea senyeha, mateano a epidermis le dermis a fetoha a bataletseng, 'me botenya ba epidermis bo fokotseha. E le mokoallo o ka ntle oa 'mele oa motho, epidermis e amana ka ho toba le tikoloho e ka ntle' me e ameha habonolo ke lintho tse sa tšoaneng tse ka ntle. Botsofali ba Epidermal bo bontša habonolo tšusumetso ea lilemo le lintho tse kantle ho botsofali ba motho.

Ho epidermis ea letlalo le tsofalang, ho fetoha ha boholo, morphology le litšila tsa lisele tsa basal layer lia eketseha, mateano a epidermis le dermis butle-butle a fetoha a bataletseng, lesela la epidermal le fetoha le sa tebang, 'me botenya ba epidermis bo fokotseha. Botenya ba Epidermal bo fokotseha ka hoo e ka bang 6.4% ka lilemo tse leshome, 'me bo fokotseha ka potlako ho basali. Botenya ba Epidermal bo fokotseha ka lilemo. Phetoho ena e bonahala haholo libakeng tse pepenene, ho kenyelletsa le bokaholimo ba sefahleho, molala, matsoho le liphatla. Li-Keratinocyte li fetola sebopeho ha letlalo le ntse le tsofala, le ba lekhutšoane le ho nona, ha keratinocyte e ntse e eketseha ka lebaka la phetoho e khutšoanyane ea epidermal, nako ea ho nchafatsa epidermis ea botsofali ea eketseha, mosebetsi oa ho ata ha lisele tsa epidermal oa fokotseha, 'me epidermis e ba mosesaane. tšesaane, ho etsa hore letlalo le lahleheloe ke elasticity le matsutsuma.

Ka lebaka la liphetoho tsena tsa morphological, epidermis-dermis junction ha e thata ebile e kotsing ea tšenyo ea matla a kantle. Palo ea melanocyte e fokotseha butle ka mor'a lilemo tse 30, matla a ho ata a fokotseha, 'me mosebetsi oa enzymatic oa melanocyte o fokotseha ka tekanyo ea 8% -20% ka lilemo tse leshome. Le hoja letlalo le se bonolo ho ba lets'oao, li-melanocyte li atisa ho ata sebakeng seo ho etsa matheba a mebala, haholo-holo libakeng tse chesitsoeng ke letsatsi. Lisele tsa Langerhans le tsona li fokotsehile, li etsa hore ts'ebetso ea 'mele ea ho itšireletsa mafung e fokotsehe' me e hlaseloe ke mafu a tšoaetsanoang.

Setlolo sa letlaloMochini o ka sebelisoa ho bona mats'ope a letlalo la sefahleho, sebopeho, tahlehelo ea collagen le sefahleho sa sefahleho ho thusa ho lemoha botsofali ba letlalo la sefahleho.
