Nws kwv yees li 52-75 hnub hauv daim tawv nqaij, 4-14 hnub hauv plab, 41-75 hnub hauv cov gingiva thiab 25 hnub hauv pliaj. Cov kab mob epithelial no yog tsim los ntawm cytoskeleton uas tsim cov qauv txheej txheem ntawm lub cell.
Cov txheej txheem ntawm Keratinization yog dab tsi?
Keratinization yog hais txog cov xwm txheej cytoplasmic uas tshwm sim hauv cytoplasm ntawm epidermal keratinocytes thaum lawv qhov sib txawv ntawm qhov kawg. Nws koom nrog tsim ntawm keratin polypeptides thiab lawv cov polymerization rau hauv keratin intermediate filaments (tonofilaments). … Keratins ntxiv rau ib khub kuj muaj qee zaum pom.
txheej txheem ntawm keratinization yog dab tsi thiab nws tshwm sim li cas?
Y Protein koom nrog hauv keratinization,
txheej txheem uas cov cytoplasm ntawm cov hlwb sab nraud ntawm vertebrate epidermis hloov los ntawm keratin. Keratinization tshwm sim hauv stratum corneum, plaub, plaub hau, claws, rau tes, hooves, thiab horns.
Cov txheej txheem Keratinization pib qhov twg?
Keratinization pib hauv the stratum spinosum, txawm tias qhov tseeb keratinocytes pib hauv stratum basale. Lawv muaj cov nuclei loj daj ntseg vim lawv ua haujlwm hauv kev tsim cov proteins fibrilar, hu ua cytokeratin, uas tsim nyob rau hauv cov hlwb sib sau ua ke ua tonofibrils.
YDab tsi yog Keratinization sai?
Ntawm no, peb txhais (i) 'keratinization sai sai'raws li mob qog noj ntshav los yog pom tseeb squa- mous maturation ntawm lossis peripheral mus rau cov qog nqaij hlav uas tsis loj hlob ntawm lub zes(Daim duab 4A) thiab (ii) 'comedo-necrosis ntawm cov qog nqaij hlav tsis loj hlob' raws li coagulative necrosis tsim ntawm cov uas tsis yog-keratinizing/tsis-maturing qog cell zes (…
