Keratinization yog hais txog cov xwm txheej cytoplasmic uas tshwm sim hauv cytoplasm ntawm epidermal keratinocytes thaum lawv qhov sib txawv ntawm qhov sib txawv. Nws koom nrog kev tsim cov keratin polypeptides thiab lawv cov polymerization rau hauv keratin intermediate filaments (tonofilaments).
Nws siv sijhawm ntev npaum li cas rau Keratinization tshwm sim?
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.
Nyob rau hauv qhov twg stratum ua cov txheej txheem hu ua Keratinization pib?
- 3 - lub stratum granulosum :no cov txheej txheem keratinization pib thiab cov hlwb pib tuag. Cov txheej no hu ua granulosum vim hais tias cov hlwb muaj granules ntawm precursor ntawm keratin.
Cov txheej txheem ntawm Keratinization tshwm sim nyob qhov twg?
txheej txheem ntawm keratinization yog dab tsi? Raws li cov hlwb tshiab loj hlob thiab nthuav dav, lawv raug thawb mus rau qhov chaw uas cov khoom noj tsis zoo. Cov hlwb tawv thiab tuag. Ntau ntawm cov hlwb tuag no sib sau ua ke hauv stratum corneum txheej ntawm epidermis.
Keratinization yog dab tsi?
Keratinized cov ntaub so ntswg, tseem hu ua keratinized mucosa, hais txog cov ntaub so ntswg ncig koj cov hniav ntawm qhov chaw uas lawv ntsib cov pos hniav. Lo lus "keratinized" yog siv los piav qhia cellsuas tsim cov protein ntau hu ua keratin, ua rau lawv muaj zog thiab zoo dua ntawm kev thaiv.
