Cov dawb nto ntawm cov ntaub so ntswg epithelial feem ntau raug cov kua los yog cua, thaum hauv qab nto yog txuas rau hauv qab daus membrane. Yooj yim cov ntaub so ntswg epithelial kab kab noj hniav hauv lub cev thiab cov kab ke. Yooj yim epithelial cov ntaub so ntswg cov cell tsim cov kab hauv cov hlab ntshav, ob lub raum, tawv nqaij, thiab lub ntsws.
Hauv qhov no, koj hu dab tsi rau sab sauv lossis dawb ntawm cov nqaij epithelial?
Cov sab saum toj ntawm epithelium yog dawb , lossis nthuav tawm sab nraud ntawm lub cev lossis rau kab noj hniav sab hauv lub cev. Lub hauv paus nto nyob ntawm qhov txuas cov ntaub so ntswg . Ib qho nyias, txheej txheej sab nrauv hu ua hauv qab daus daim ntawv tsim ntawm epithelial cov ntaub so ntswg thiab txuas cov ntaub so ntswg.
Ib tus kuj tseem yuav nug tau, dab tsi yog lub hauv paus ntawm cov ntaub so ntswg epithelial? Basal nto . Hauv histology, basal nto yog lub qab ntug ntawm tes lossis cov ntaub so ntswg nyob ib sab rau hauv qab daus membrane. Tshwj xeeb, cov cov ntaub so ntswg epithelial yog ib pawg ntawm cov cell (hu ua epithelial cov ntaub so ntswg cell) uas sib koom ua ke kom ua haujlwm zoo ib yam.
Ua li no, hom ntaub so ntswg epithelial twg nyob ntawm daim tawv nqaij?
Stratified squamous epithelium : Cov ntaub so ntswg no yog cov khoom koj pom txhua hnub - koj cov tawv nqaij sab nraud, lossis daim tawv nqaij. Cov ntaub so ntswg multilayered muaj squamous hlwb nyob rau sab nraud ntxiv rau cov txheej tob ntawm cuboidal lossis columnar hlwb.
Cov ntaub so ntswg epithelial yog dab tsi?
Cov ntaub so ntswg epithelial muaj thoob plaws lub cev. Lawv tsim cov npog ntawm txhua qhov ntawm lub cev, kab kab noj hniav hauv lub cev thiab cov kabmob hauv nruab nrog, thiab yog qhov 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.

Lub sijhawm rau cov ntaub so ntswg dawb nyob ib ncig ntawm lub qhov muag thiab tsim lub hauv paus txheej txheem ntawm lub ntiaj teb yog dab tsi?
Qhov muag. Cov ntaub so ntswg dawb nyob ib ncig ntawm lub qhov muag thiab ua lub hauv paus tseem ceeb ntawm lub ntiaj teb yog. iris, lub cev ciliary, choroid. Cov qauv ntawm cov kab mob uveal, lossis uvea, yog. dej lom zem
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 ntawm cov ntaub so ntswg epithelial yog lub epidermis ntawm daim tawv nqaij?
Stratified squamous epithelium
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
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
