thiab columnar epithelium columnar epithelium Columnar epithelial hlwb yog siab dua li lawv qhov dav: lawv zoo ib yam li pawg kab hauv ib txheej txheej epithelial, thiab feem ntau pom nyob rau hauv ib leeg. - txheej txheej. … Qhov no hu ua pseudostratified, columnar epithelia. Qhov no cellular npog muaj cilia ntawm lub apical, los yog dawb, nto ntawm lub hlwb. https://courses.lumenlearning.com › tshooj › epithelial-tissues

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,diffusion, thiab sensory txais.
3 yam ntawm cov ntaub so ntswg epithelial yog dab tsi?
Txawm tias muaj ntau ntau hom ntawm cov ntaub so ntswg epithelial tag nrho cov ntaub so ntswg epithelial tsuas muaj tsib yam ntxwv, cov no yog cellularity, polarity, txuas, vascularity, thiab rov tsim dua. Cellularity raws li lub npe qhia txhais tau hais tias lub epithelium yog tsim los ntawm yuav luag tag nrho cov hlwb.
5 yam ntxwv ntawm cov ntaub so ntswg epithelial yog dab tsi?
Txawm hais tias muaj ntau yam sib txawv ntawm cov ntaub so ntswg epithelial tag nrho cov ntaub so ntswg epithelial tsuas muaj tsib yam ntxwv, cov no yog cellularity, polarity, txuas, vascularity, thiab rov tsim dua.
Cov ntaub so ntswg epithelial yog dab tsi?
Epithelial hlwb feem ntau yog tus cwj pwm los ntawm cov polarized faib ntawm cov organelles thiab cov membrane-bound proteins ntawm lawv basal thiab apical nto. Cov qauv tshwj xeeb pom muaj nyob hauv qee lub hlwb epithelial yog kev hloov kho rau cov haujlwm tshwj xeeb.

Lub sijhawm ua cov ntaub so ntswg yog dab tsi yog qhov tseeb ntawm cov kauj ruam?
Nws muaj peb kauj ruam tseem ceeb hauv kev ua cov ntaub so ntswg, uas yog: 'dehydration', 'clearing', thiab 'infiltration'. Txhua kauj ruam ntawm kev ua txheej txheem suav nrog kev sib kis ntawm cov tshuaj rau hauv cov ntaub so ntswg thiab dispersion ntawm cov tshuaj yav dhau los hauv koob.
Dab tsi yog peb cov ntaub qhwv cov ntaub so ntswg hauv cov leeg?
Cov ntaub so ntswg interstitial ntawm cov leeg yog subdivided rau hauv epimysium epimysium Lub epimysium yog cov ntaub so ntswg ntom ntom uas nyob ib puag ncig tag nrho cov leeg nqaij. Lub epimysium feem ntau muaj ntau pob (fascicles) ntawm cov leeg nqaij.
Dab tsi yog cov kab mob photosynthetic pom nyob rau hauv cov ntaub so ntswg ntawm coral?
Feem ntau cov pob zeb tsim cov pob zeb muaj cov photosynthetic algae, hu ua zooxanthellae, uas nyob hauv lawv cov ntaub so ntswg. Corals thiab algae muaj kev sib raug zoo. Lub coral muab cov algae nrog kev tiv thaiv ib puag ncig thiab cov tebchaw uas lawv xav tau rau photosynthesis.
Puas cov ntaub so ntswg epithelial puas muaj cov ntaub so ntswg hauv qab daus?
Ntseeg ntawm Epithelia Epithelial hlwb txuas rau ib hom tshwj xeeb ntawm extracellular matrix hu ua basal lamina basal lamina Lub basal lamina yog txheej ntawm extracellular matrix secreted los ntawm cov epithelial hlwb, ntawm uas lub epithelium zaum.
