Qhov loj tshaj sib txawv nruab nrab yooj yim thiab stratified cov ntaub so ntswg yog uas 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 nyob rau hauv qab daus membrane, uas yog ib daim nyias nyias tiv thaiv uas nyob sab nraum cov nqaij.
Ntxiv mus, dab tsi yog qhov txawv ntawm cov ntaub so ntswg yooj yim thiab stratified epithelial?
A yooj yim epithelium muaj cov cell uas tsim ib txheej uas txuas rau hauv qab daus. A stratified epithelium ntawm qhov tod tes, muaj ntau txheej txheej ntawm cov cell uas tsuas yog txheej txheej hauv paus txuas rau hauv qab daus daim nyias nyias.
Qhov thib ob, dab tsi yog cov qog nqaij hlav epithelium? Glandular epithelium yog hom epithelial cov ntaub so ntswg cov ntaub so ntswg uas npog cov qog (ob qho exocrine thiab endocrine) ntawm peb lub cev. Lawv lub luag haujlwm tseem ceeb yog kev zais cia. Ob leeg endocrine thiab exocrine qog tsim lawv cov secretions los ntawm qog epithelium ntawm cov cell tshwj xeeb hu ua goblet cells.
Ib yam li ntawd, nws tau nug, qhov txawv ntawm qhov yooj yim stratified thiab pseudostratified epithelial cov ntaub so ntswg quizlet yog dab tsi?
Paub qhov txawv ntawm squamous, cuboidal, thiab columnar epithelial hlwb. Yooj yim - Ib txheej ntawm cov hlwb. Stratified - Ntau tshaj ib txheej, tsuas yog basal txheej txuas. Pseudostratified - Ib txheej, txhua qhov txuas nrog hauv qab daus, tsis yog stratified txawm tias zoo li nws yog.
Qhov txawv ntawm qhov yooj yim squamous epithelium thiab stratified squamous epithelium yog dab tsi?
Number of Cell Layers A loj qhov sib txawv ntawm qhov yooj yim squamous epithelium thiab stratified squamous epithelium yog lub yooj yim squamous epithelium muaj ib txheej txheej ntawm tes thaum stratified squamous epithelium muaj ob peb txheej ntawm tes.

Dab tsi yog qhov sib txawv ntawm squamous yooj yim thiab yooj yim cuboidal thiab columnar yooj yim?
Piv txwv li, yooj yim squamous epithelial cov ntaub so ntswg piav qhia ib txheej ntawm cov cell uas tiaj thiab nplai zoo li cov duab. Cuboidal epithelium muaj cov cell uas nws qhov siab thiab dav yog kwv yees tib yam. Columnar epithelium muaj cov cell siab dua li lawv dav
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm cov khoom sib tsoo thiab qhov kov zoo?
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Dab tsi yog qhov sib txawv ntawm cov ntaub so ntswg sib txuas tsis tu ncua thiab cov ntaub so ntswg sib txuas tsis sib xws?
Cov ntaub so ntswg sib txuas tsis sib thooj muaj cov fibers uas tsis tau sib dhos ua ke zoo ib yam li cov ntaub so ntswg sib txuas ib ntus. Cov ntaub so ntswg sib txuas tsis sib thooj muaj feem ntau ntawm cov fibers collagen. Nws muaj cov khoom hauv av tsawg dua li cov ntaub so ntswg sib txuas
Dab tsi yog qhov txawv ntawm kev sib tw ntawm cov tswv yim thiab cov koom haum xoob?
Kev sib txuas ntawm cov tswv yim tuaj yeem tsis muaj tseeb lossis kev hais lus tuaj yeem taug kev ntawm cov tsheb ciav hlau ntawm kev xav. Qhov tsis muaj tseeb ntawm kev xoob ntawm cov koom haum uas tau pom hauv tus mob schizophrenia yuav tsum sib piv nrog kev ya davhlau ntawm cov tswv yim uas qhia txog tus neeg hypomania. Kev txo qis ntawm cov koom haum tseem hu ua tus tub rog txoj kev xav
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
