Cov ntaub so ntswg epithelial yog tsim los ntawm cov cell tso ua ke hauv nplooj ntawv nrog cov cell sib txuas sib koom ua ke. Epithelial Cov txheej yog avascular, tab sis innervated. Cov qog, xws li exocrine thiab endocrine, yog tsim los ntawm cov ntaub so ntswg epithelial thiab cais raws li lawv cov secretions raug tso tawm.
Hauv qhov no, cov ntaub so ntswg epithelial yog dab tsi?
Cov ntaub so ntswg epithelial muaj thoob plaws lub cev. Lawv tsim cov npog ntawm tag nrho lub cev qhov chaw, kab lub cev kab noj hniav thiab hollow lub cev, thiab yog cov loj cov ntaub so ntswg hauv cov qog. Lawv ua ntau yam haujlwm uas suav nrog kev tiv thaiv, tso pa tawm, nqus dej, tso zis, pom, nthuav tawm, thiab hnov qab zoo.
Ib sab saum toj no, ob sab ntawm epithelium yog dab tsi? Muaj ob laj epithelial cov ntaub so ntswg: npog thiab hauv ob sab phlu epithelium cov ntaub so ntswg npog sab nraum nto ntawm lub cev thiab kab hauv nruab nrog cev.
Zoo sib xws, nws tau nug, 6 hom epithelial cov ntaub so ntswg yog dab tsi?
Tus naj npawb ntawm cov txheej txheem 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.

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
Yuav ua li cas yog lub sij hawm rau ib tug malignant lesion nyob rau hauv lub epithelial cov ntaub so ntswg ntawm qhov ncauj kab noj hniav?
Leukoplakia (b) Lub sij hawm rau kev mob qog nqaij hlav hauv cov ntaub so ntswg ntawm qhov ncauj yog dab tsi? mob qog noj ntshav (c)
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
