Piv txwv li, yooj yim squamous epithelial cov ntaub so ntswg piav qhia ib txheej ntawm cov cell uas tiaj thiab zoo ib yam li cov duab. Cuboidal epithelium muaj cov hlwb uas nws qhov siab thiab dav yog kwv yees tib yam. Kab ntawv epithelium muaj cov cell siab dua li lawv dav.

Hauv qhov no, qhov txawv ntawm qhov yooj yim thiab squamous yog dab tsi?

Qhov Sib Txawv Ntawm Yooj Yim Squamous Epithelium thiab Stratified Squamous Epithelium. Lub ntsiab qhov sib txawv ntawm qhov yooj yim squamous epithelium thiab stratified ua squamous epithelium yog li ntawd yooj yim squamous epithelium muaj ib txheej ntawm tes ib yam li stratified ua squamous epithelium muaj ob peb txheej txheej ntawm tes.

Qhov thib ob, dab tsi yog ob tus yam ntxwv ntawm kab ntawv epithelium yooj yim? Yooj yim columnar epithelium suav nrog ib txheej ntawm cov cell uas siab dua li lawv dav. Hom kab mob epithelia no ua rau txoj hnyuv me uas nws nqus cov khoom noj los ntawm lumen ntawm txoj hnyuv. Yooj yim columnar epithelia kuj tseem nyob hauv plab uas nws zais cov kua qaub, zom zaub mov zom zaub mov thiab mucous.

Tom qab ntawd, qhov sib txawv ntawm qhov yooj yim thiab stratified squamous epithelium yog dab tsi?

Qhov loj tshaj sib txawv ntawm qhov yooj yim thiab stratified cov ntaub so yooj yim cov ntaub so ntswg yog ib txheej tuab thaum stratified cov ntaub so ntswg yog ntau txheej. Txhua epithelial cov ntaub so ntswg cov ntaub so ntswg nyob hauv qab daus daim nyias nyias, uas yog daim nyias nyias tiv thaiv nyob rau sab nraud ntawm cov ntaub so ntswg.

Qhov txawv ntawm kev hloov pauv thiab Pseudostratified epithelial cov ntaub so ntswg yog dab tsi?

kev hloov pauv yog qhov txawv txav tshwm sim, cov cell zoo li cuboidal. Pseudostratified yog ib txheej tab sis cov cell thiab nuclei nyob ntawm txawv qhov siab muab qhov pom ntawm ntau txheej.
