niam hlwb uas faib rau hauv cov basal txheej (germinativum) tsim cov ntxhais tshiab. … Cov hlwb "tuag" no tau qhuav tawm thiab tsis muaj nuclei. desquamation. txheej txheem nyob rau hauv uas keratinocytes txuas ntxiv los ntawm daim tawv nqaij thiab hloov los ntawm cov hlwb tshiab tuaj rau saum npoo los ntawm qis stratums; aka cell turnover.
txheej txheem ntawm cov tawv nqaij ntawm cov tawv nqaij pib qhov twg?
The Basal Cell Layer Cov hlwb basal txuas ntxiv sib faib, thiab cov hlwb tshiab tas li thawb cov laus mus rau ntawm daim tawv nqaij, qhov chaw lawv thiaj li poob.. Lub basal cell txheej tseem hu ua stratum germinativum vim qhov tseeb tias nws yog tas li germinating (tsim) hlwb tshiab.
txheej txheem ntawm kev ua keratinocytes yog dab tsi?
Keratinocytes proliferate nyob rau hauv lub basal txheej ntawm lub epidermis thiab pib sib txawv ntawm lawv txoj kev mus rau saum npoo, undergoing gradual differentiation. Thaum cov txheej txheem no, lawv tau hloov pauv lawv cov morphology thiab pib tsim cov keratin, cytokines, loj hlob yam, interleukins thiab ntxiv cov khoom.
Lub npe ntawm cov txheej txheem ntawm daim tawv nqaij tawv nqaij daim tawv nqaij daim tawv nqaij daim tawv nqaij daim tawv nqaij daim tawv
Desquamation yog txheej txheem ntuj tsim los ntawm cov tawv nqaij tsim, sloughed, thiab hloov. Cov txheej txheem desquamation tshwm sim nyob rau hauv txheej txheej ntawm daim tawv nqaijhu ua epidermis.
Dab tsi yog txheej txheem ntawm kev tshem cov hlwb los ntawm qhov chaw ntawm stratum corneum hu ua?
Desquamation, txheej txheem ntawm cov cell los ntawm qhov chaw ntawm stratum corneum, sib npaug proliferating keratinocytes uas tsim nyob rau hauv lub stratum basale. Cov hlwb no tsiv mus los ntawm cov epidermis mus rau saum npoo ntawm kev taug kev uas yuav siv sijhawm li kaum plaub hnub.
