Cov tawv nqaij nto (epidermis) yog ua keratinized , feem ntau hnyav li ntawm cov leeg thiab xib teg. Hauv daim duab no, txheej txiv kab ntxwv (hu ua stratum corneum) yog ua keratinized txheej Nonkeratinized s.s.s ua. epithelium cov ntaub so ntswg muaj cov hlwb nyob txhua txoj hauv kev mus rau qhov dawb, tsis muaj cov kab mob tuag no.
Kuj paub, qhov txawv ntawm Keratinized thiab tsis Keratinized epithelium yog dab tsi?
Keratinized epithelium yog impervious rau dej. (1). Tsis - keratinized epithelium tsim cov kab hauv cov kab noj hniav, pharynx thiab txoj hlab pas. Cov tawv nqaij ntawm tsis - keratinized daim tawv nqaij yog nyob ntawm tes.
Ib qho ntxiv, Keratinized thiab Nonkeratinized stratified squamous epithelium yog dab tsi? Cov haujlwm ntawm keratinized thiab nonkeratinized stratified squamous epithelium yog dab tsi? . Muab kev tiv thaiv rau lub nruab nrog cev thiab txoj kev hla mus. Cov ntaub so ntswg kertinized muab ob qho kev tiv thaiv dej thiab tiv thaiv tawv nqaij.
Ib sab saum toj no, Nonkeratinized stratified squamous epithelium yog dab tsi?
Stratified Squamous Epithelium . Stratified squamous epithelium ntawm txoj hlab pas yog ntawm tsis ua hauj lwm yam (Daim duab 5.1). Qhov no suav nrog ob txog peb txheej ntawm cov hauv paus sib npaug hauv cov cell hauv cheeb tsam hauv paus uas me me nrog lub siab nuclear: cytoplasmic piv thiab hyperchromatic nuclei.
Tsis Keratinized txhais li cas?
Kev kho mob Txhais ntawm nonkeratinized : tsis cim los ntawm kev tsim lossis hloov pauv mus rau keratin lossis cov nqaij mos keratinous: tsis keratinous nonkeratinized epithelium qhov chaw.

Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
Dab tsi yog stratified squamous keratinized epithelium?
(Cov tawv nqaij Palmar) Cov cell nyob saum npoo ntawm cov kab ke sib xyaw ua ke keratinized epithelium yog tiaj heev. Tsis tsuas yog lawv tiaj tus, tab sis lawv tsis muaj txoj sia nyob lawm. Lawv tsis muaj nucleus lossis organelles. Lawv tau ntim nrog cov protein hu ua keratin, uas ua rau peb cov tawv nqaij tsis muaj dej
Cov qog epithelium sib txawv li cas los ntawm epithelium yooj yim thiab stratified?
Qhov sib txawv loj tshaj plaws ntawm cov ntaub so ntswg yooj yim thiab stratified yog cov ntaub so ntswg yooj yim yog ib txheej tuab thaum cov ntaub so ntswg stratified yog ntau txheej. Txhua cov ntaub so ntswg epithelial nyob ntawm lub hauv qab daim nyias nyias, uas yog daim nyias nyias tiv thaiv nyob rau sab nraud ntawm cov ntaub so ntswg
Keratinized stratified squamous epithelium txhais li cas?
(Cov tawv nqaij Palmar) Cov cell nyob saum npoo ntawm cov kab ke sib xyaw ua ke keratinized epithelium yog tiaj heev. Tsis tsuas yog lawv tiaj tus, tab sis lawv tsis muaj sia nyob lawm. Lawv tsis muaj nucleus lossis organelles. Lawv tau ntim nrog cov protein hu ua keratin, uas ua rau peb cov tawv nqaij tsis muaj dej
Dab tsi yog qhov txawv ntawm qhov tseeb qhov pib thiab qhov sib txawv qhov pib?
Qhov pib tsis txaus yog qhov tsawg kawg ntawm kev txhawb siab xav tau rau ib tus neeg kom pom qhov kev txhawb siab 50 feem pua ntawm lub sijhawm. Qhov sib txawv ntawm qhov sib txawv yog qhov sib txawv me tshaj hauv kev txhawb nqa uas tuaj yeem kuaj pom 50 feem pua ntawm lub sijhawm
