Cov Ntsiab Lus
- Muaj peb tus thawj xibfwb ntawm tes cov duab txuam nrog cov kab mob epithelial : squam ua epithelium cov ntaub so ntswg , kub epithelium cov ntaub so ntswg , thiab columnar epithelium cov ntaub so ntswg .
- Muaj peb txoj hauv kev piav qhia txheej txheej ntawm epithelium cov ntaub so ntswg : yooj yim, stratified, thiab pseudostratified.
Ntxiv mus, dab tsi yog epithelial cells?
Cov kab mob epithelial yog ib hom ntawm tes uas ua kab ntawm koj lub cev. Lawv tau pom ntawm koj cov tawv nqaij, cov hlab ntsha, cov tso zis, thiab cov nruab nrog cev. Nws yog ib txwm muaj me me ntawm cov kab mob epithelial hauv koj cov zis. Tus nqi loj yuav qhia txog kev kis mob, mob raum, lossis lwm yam mob hnyav.
Ib tus kuj tseem yuav nug tau, 4 lub luag haujlwm ntawm cov ntaub so ntswg epithelial yog dab tsi? Lawv ua ntau yam haujlwm uas suav nrog kev tiv thaiv , zais zis , nqus tau , tso tawm, pom, nthuav tawm, thiab hnov qab hnov qab. Cov hlwb hauv cov ntaub so ntswg epithelial tau nruj nreem ua ke nrog me me intercellular matrix.
Kuj Paub, 6 hom epithelial cov ntaub so ntswg yog dab tsi?
Tus naj npawb ntawm txheej txheej ntawm tes thiab hom cell ua ke ua rau nce mus rau 6 hom sib txawv ntawm cov nqaij mos epithelial
- Yooj yim squamous epithelia.
- Yooj yim cuboidal epithelia.
- Yooj yim columnar epithelia.
- Stratified squamous epithelia.
- Stratified cuboidal epithelia.
- Stratified columnar epithelia.
Puas muaj ntaub so ntswg epithelial nyob hauv lub cev?
Cov ntaub so ntswg epithelial npog sab nraum ntawm lub cev thiab kab nruab nrog cev, hlab ntsha (ntshav thiab qog ntshav), thiab kab noj hniav. Epithelial cov cell tsim cov txheej nyias nyias ntawm cov cell hu ua endothelium, uas yog sib txuas nrog sab hauv cov ntaub so ntswg kab hauv nruab nrog cev xws li lub paj hlwb, lub ntsws, tawv nqaij, thiab lub plawv.
Pom zoo:
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
4 hom epithelial cov ntaub so ntswg yog dab tsi?
Cov ntaub so ntswg epithelial yooj yim feem ntau cais los ntawm cov duab ntawm lawv cov hlwb. Plaub chav kawm tseem ceeb ntawm epithelium yooj yim yog: 1) squamous yooj yim; 2) cuboidal yooj yim; 3) yooj yim columnar; thiab 4) pseudostratified
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
Qhov twg ntawm cov hauv qab no yog kev ua haujlwm ntawm cov ntaub so ntswg epithelial?
Kev ua haujlwm ntawm cov hlwb epithelial suav nrog kev zais cia, xaiv qhov nqus, tiv thaiv, kev thauj mus los, thiab kev hnov. Cov txheej epithelial tsis muaj cov hlab ntshav, yog li lawv yuav tsum tau txais kev txhawb nqa los ntawm kev nthuav tawm cov tshuaj los ntawm cov ntaub so ntswg sib txuas, los ntawm cov hauv qab daus
