cov ntaub so ntswg epithelial yog dav thoob plaws hauv 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 ntaub so ntswg loj hauv qog. Lawv ua ntau yam haujlwm uas suav nrog tiv thaiv, zais cia, nqus, tshem tawm, pom, nthuav tawm, thiab txais kev hnov qab
Dab tsi yog 3 lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg epithelial?
Nyob rau hauv cov ntaub so ntswg epithelial, cov hlwb raug kaw nrog me me los yog tsis muaj extracellular matrix tshwj tsis yog rau basal lamina uas cais cov epithelium los ntawm cov ntaub so ntswg. Lub luag haujlwm tseem ceeb ntawm epithelia yog tiv thaiv los ntawm ib puag ncig, kev pab them nqi, tso tawm thiab tso tawm, nqus, thiab pom
Cov qauv ntawm cov hlwb epithelial pab nws txoj haujlwm li cas?
Epithelia hlwb kuj muaj cov qauv ntxiv uas pab txhawb lawv cov dej num. Cov hlwb epithelial koom nrog absorptionfeem ntau muaj microvilli, ntiv tes zoo li qhov projections ntawm plasma membrane, uas ua rau thaj tsam ntawm cov plasma membrane, ua rau kom muaj txiaj ntsig zoo ntawm cov khoom.
Vim li cas cov ntaub so ntswg epithelial thiaj tseem ceeb?
Epithelial cov ntaub ntawv ib thaiv ntawm lub cev thiab ib puag ncig sab nraud thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv, pom, nqus, tso tawm, thiab hnov qab. Kev tsim kho sai ntawm cov hlwb epithelial yog qhov tseem ceeb rau lawv txoj haujlwm tiv thaiv.
Yuav ua li cas yog tias peb tsis muaj cov ntaub so ntswg epithelial?
Yuav ua li cas yog tias peb tsis muaj cov ntaub so ntswg epithelial? Yog tsis muaj cov ntaub so ntswg epithelial koj yuav tsis muaj peev xwm txaus siab rau nws, rau koj yuav plam tag nrho cov kev xav. Tsis tsuas yog lawv zais cov ntaub ntawv tab sis cov ntaub so ntswg epithelial ntawm txoj hnyuv me yog lub luag haujlwm rau kev nqus cov as-ham!

Vim li cas cov ntaub so ntswg meristematic muaj cov nucleus tseem ceeb?
Meristematic hlwb muaj lub hauv paus tseem ceeb, ntom cytoplasm thiab tsis muaj vacuoles thiab vim tias: cov cells tsis khaws cov khoom noj lossis cov khoom pov tseg. Yog li lawv tsis muaj vacuole. Raws li vacuoles muaj cell sap thiab muab rigidity thiab turgidity rau lub cell .
Puas yog cov ntaub so ntswg stratified epithelial?
Ib stratified epithelium yog ib hom ntawm cov ntaub so ntswg epithelialuas yog tsim los ntawm ntau tshaj ib txheej ntawm cov hlwb epithelial. Lub basal txheej yog tib yam uas nyob rau hauv kev sib cuag nrog basal lamina. … Stratified epithelia feem ntau muaj lub luag haujlwm los yog kev tiv thaiv .
Puas yog cov ntaub so ntswg adipose suav tias yog cov ntaub so ntswg txuas?
Adipose cov ntaub so ntswg, lossis cov ntaub so rog, cov ntaub so ntswgsuav nrog cov roj ntsha tseem ceeb (adipose hlwb, lossis adipocytes), tshwj xeeb los ua ke thiab muaj cov roj loj loj, hauv cov qauv network ntawm fibers . Puas yog cov ntaub so ntswg adipose txuas?
Cov ntaub so ntswg epithelial twg muaj nyob rau hauv txoj kev ua pa?
feem ntau ntawm cov ntoo ua pa, los ntawm qhov ntswg mus rau lub bronchi, yog kab los ntawm pseudostratified columnar pseudostratified columnar Pseudostratified epithelium yog ib hom epithelium uas, txawm hais tias muaj tsuas yog ib txheej ntawm cov hlwb.
Vim li cas cov ntaub so ntswg epithelial yog avascular?
Thaum cov ntaub so ntswg hauv lub cev feem ntau yog vascular (muaj cov hlab ntsha), epithelium yog avascular (a-vas′ku-lar), txhais tau tias nws tsis muaj cov hlab ntsha. Epithelial hlwb tau txais lawv cov as-ham los ntawm capillaries hauv cov ntaub so ntswg txuas .
