4 lub hlwb ntawm daim tawv nqaij yog dab tsi?
Muaj 4 hom tawv nqaij ntawm tib neeg xws li Keratinocytes, Melanocytes, Langerhans cells, thiab Merkel cells.
Puas yog cov hlwb hauv cov epidermis tuag?
Nco ntsoov tias tsis muaj cov hlab ntsha hauv epidermis yog li cov hlwb tau txais lawv cov as-ham los ntawm kev sib kis los ntawm cov ntaub so ntswg hauv qab no, yog li cov hlwb ntawm txheej txheej sab nrauv no tuagStratum Corneum cell flake tawm. Qhov no hu ua dandruff thiab muaj peev xwm ua tau 40 phaus ntawm nws tsim nyob rau hauv lub neej.
cov hlwb epidermal yog dab tsi?
Cov epidermis feem ntau muaj keratinocytes (proliferating basal thiab txawv suprabasal), uas muaj 90% ntawm nws cov hlwb, tab sis kuj muaj melanocytes, Langerhans hlwb, Merkel hlwb, thiab inflammatory hlwb. Epidermal thickenings hu ua Rete ridges (los yog rete pegs) txuas mus rau hauv qab ntawm dermal papillae.
Epdermis muaj dab tsi?
34.1 Taw qhia. Lub epidermis ntawm daim tawv nqaij yog ib tug tas li renewing stratified squamous epithelium. Nws muaj feem ntau ntawm keratinocytes, tab sis kuj ntawm Langerhans hlwb, melanocytes, thiab Merkel hlwb so ntawm lub dermis txhawb nqa uas muaj cov hlab ntsha thiab cov hlab ntsha, uas txhawb cov epidermis..
