Yooj yim squamous epithelia yog pom hauv capillaries, alveoli, glomeruli, thiab lwm cov ntaub so ntswg uas xav tau kev nthuav tawm sai. Xovtooj yog tiaj nrog flattened thiab oblong nuclei. Nws tseem hu ua pavement epithelium cov ntaub so ntswg vim nws cov pobzeb- nyiam tsos. Cov ntaub so ntswg yog qhov hnyav heev, thiab tsim cov kab me me.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yooj yim squamous epithelium zoo li nyob rau hauv lub tshuab tsom?
A squamous epithelial cov ntaub so ntswg ntawm tes zoo li tiaj tus hauv qab lub tshuab tsom iav . Ib cuboidal epithelial ntawm tes zoo li nyob ze rau ib lub square. A columnar epithelial ntawm tes zoo li ib kem lossis ib lub duab plaub siab. Cov hlwb feem ntau yuav yog ib qho ntawm peb qhov yooj yim ntawm tes - squamous kub, or columnar.
Qhov thib ob, qhov yooj yim squamous zoo li cas? Cov cell hauv yooj yim squamous epithelium muaj cov tsos ntawm cov nplai nyias. Squamous cell nuclei zoo li tiaj, kab rov tav, thiab elliptical, tsom iav ntawm daim ntawv. Mesothelium yog a yooj yim squamous epithelium uas tsim cov txheej txheej saum npoo ntawm cov kab mob uas ua rau kab noj hniav hauv lub cev thiab sab hauv nruab nrog cev.
Tom qab ntawd, koj yuav txheeb xyuas qhov yooj yim squamous epithelium li cas?
Yog tias epithelium cov ntaub so ntswg tsuas yog ib lub cell-txheej tuab, ces nws yog hu ua yooj yim epithelium thiab yog tias nws ntau dua ib txheej tuab, tom qab ntawd nws hu ua stratified epithelium cov ntaub so ntswg . Thaum kawg, nws tseem ceeb heev rau txiav txim cov duab ntawm cov hlwb apical (cov hlwb ntawm qhov dawb).
Dab tsi yog qhov yooj yim squamous epithelium muaj nuj nqi?
Yooj yim squamous epithelium Hom no epithelium kab sab hauv ntawm tag nrho cov hlab ntsha (endothelium), tsim cov phab ntsa ntawm alveolar sacs nyob rau hauv lub ntsws thiab kab lub cev kab noj hniav (mesothelium). Qhov tseem ceeb muaj nuj nqi ntawm yooj yim squamous epithelia yog los pab txhawb kev nthuav dav ntawm cov roj thiab cov lwg me me.

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 piav qhia ntawm yooj yim columnar epithelium?
Ib qho yooj yim columnar epithelium yog columnar epithelium uas yog uni-layered. Nyob rau hauv tib neeg, ib qho yooj yim columnar epithelium kab feem ntau cov kab mob ntawm lub plab zom mov nrog rau lub plab, hnyuv me, thiab txoj hnyuv loj. Yooj yim columnar epithelia kab ntawm lub tsev menyuam
Qhov yooj yim columnar epithelium muaj nuj nqi nyob qhov twg?
Ib qho yooj yim columnar epithelium muaj ib txheej ntawm cov hlwb uas siab tshaj qhov dav. Hom kab mob epithelia no yog 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 hnoos qeev
Dab tsi yog qhov yooj yim columnar epithelium zoo li?
Ib qho yooj yim columnar epithelium muaj ib txheej ntawm cov hlwb uas siab tshaj qhov dav. Hom kab mob epithelia no yog 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 hnoos qeev
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
