Stratified squamous epithelia yog cov ntaub so ntswg tsim los ntawm ntau txheej txheej ntawm cov cell so ntawm lub hauv qab daim nyias nyias, nrog cov txheej txheej sab nrauv (s) suav nrog squamous hlwb. Cov khaubncaws sab nraud povtseg tuaj yeem ua los ntawm cuboidal lossis columnar cell zoo li.
Yooj yim li ntawd, dab tsi yog txoj haujlwm ntawm stratified squamous epithelium?
kev tiv thaiv
Tsis tas li ntawd, koj yuav txheeb xyuas qhov stratified squamous epithelium li cas? Stratified squamous epithelia muaj ntau txheej ntawm cov cell nrog txheej txheej feem ntau yog squamous . Lwm cov txheej yuav muaj cov cell uas yog cuboidal thiab/lossis columnar , tab sis kev faib tawm ntawm cov epithelium cov ntaub so ntswg tsuas yog ua raws li cov duab ntawm txheej txheej sab nraud ntawm cov hlwb.
Ib qho ntxiv, dab tsi yog stratified squamous epithelium?
A stratified squamous epithelium muaj squamous (tiaj) epithelial cov cell tau teeb tsa hauv txheej raws li lub hauv paus membrane. Tsuas yog ib txheej nyob rau hauv kev sib cuag nrog cov hauv qab daus membrane; lwm cov khaubncaws sab nraud povtseg ua rau ib leeg kom muaj kev ncaj ncees.
Dab tsi yog qhov zoo ntawm stratified epithelial cov ntaub so ntswg hauv daim tawv nqaij?
Vim tawv nqaij yog qhov yooj yim rau kev puas tsuaj los ntawm kev hem sab nraud, nws muaj cov txheej tuab ntawm cov ntaub so ntswg stratified . Tej yam yooj yim cov ntaub so ntswg yog tsim los ntawm columnar hlwb, elongated ib leeg hlwb. Cov no muab kev tiv thaiv zoo dua li ib txwm yooj yim cov ntaub so ntswg , tab sis tsis ntau npaum li cov ntaub so ntswg stratified.

Dab tsi yog qhov dawb ntawm cov ntaub so ntswg epithelial?
Qhov saum npoo dawb ntawm cov ntaub so ntswg epithelial feem ntau raug rau cov kua los yog huab cua, thaum sab hauv qab txuas nrog rau hauv qab daus. Yooj yim epithelial cov ntaub so ntswg kab lub cev kab noj hniav thiab kab noj hniav. Cov kab mob yooj yim epithelial tsim cov kab hauv cov hlab ntshav, ob lub raum, tawv nqaij, thiab lub ntsws
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
Hom ntaub so ntswg sib txuas twg yog cov ntaub so ntswg?
Cov ntaub so ntswg reticular yog ib hom tshwj xeeb ntawm cov ntaub so ntswg sib txuas uas muaj nyob hauv ntau qhov chaw uas muaj cov ntsiab lus ntawm tes. Nws muaj ib tug ceg thiab mesh-zoo li tus qauv, feem ntau hu ua reticulum, vim yog kev npaj ntawm reticular fibers (reticulin). Cov fibers no yeej yog hom III collagen fibrils
Cov ntaub so ntswg yog dab tsi thiab muaj pes tsawg hom ntaub so ntswg?
Cov ntaub so ntswg yog ib pawg ntawm cov cell uas muaj cov duab zoo sib xws thiab ua haujlwm. Cov ntaub so ntswg sib txawv tuaj yeem pom hauv cov kabmob sib txawv. Hauv tib neeg, muaj plaub yam tseem ceeb ntawm cov ntaub so ntswg: epithelial, txuas, leeg, thiab leeg nqaij. Tej zaum yuav muaj ntau cov ntaub so ntswg hauv txhua qhov ntawm cov ntaub so ntswg
Dab tsi yog cov yam ntxwv ntawm cov ntaub so ntswg epithelial?
Txawm hais tias muaj ntau hom sib txawv ntawm cov nqaij mos epithelial txhua cov ntaub so ntswg epithelial tsuas muaj tsib yam ntxwv, cov no yog cellularity, polarity, txuas, vascularity, thiab rov tsim dua tshiab. Cellularity raws li lub npe qhia txhais tau tias epithelium tau tsim los yuav luag tag nrho ntawm cov cell
