cov ntaub so ntswg epithelial yog dav thoob plaws hauv lub cev. Lawv tsim npog tag nrho lub cev qhov chaw, kab lub cev kab noj hniav thiab cov kabmob hollow, thiab yog cov ntaub so ntswg loj hauv qog. Lawv ua ntau yam haujlwm uas suav nrog kev tiv thaiv, zais cia, nqus, tshem tawm, pom, nthuav tawm, thiab txais kev hnov lus.
Cov ntaub so ntswg epithelial pom nyob qhov twg?
→ Cov ntaub so ntswg epithelial yog nruj nreem ntim thiab tsim ib daim ntawv txuas ntxiv. → daim tawv nqaij, hauv ob sab phlu ntawm lub qhov ncauj, hauv ob sab ntawm cov hlab ntsha, lub ntsws alveoli thiab lub raum tubulesyog tag nrho cov ntaub so ntswg epithelial.
Yuav ua li cas lub cev muaj cov ntaub so ntswg epithelial?
Epithelial cov ntaub so ntswg npog sab nraud ntawm lub cev thiab kab hauv nruab nrog cev, hlab ntsha(ntshav thiab lymph), thiab kab noj hniav. Epithelial hlwb tsim cov txheej nyias nyias ntawm cov hlwb hu ua endothelium, uas yog sib txuas nrog cov ntaub so ntswg sab hauv ntawm lub cev xws li lub hlwb, ntsws, tawv nqaij, thiab lub plawv.
4 lub luag haujlwm ntawm cov ntaub so ntswg epithelial yog dab tsi?
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 lus.
Tus yam ntxwv tseem ceeb ntawm cov ntaub so ntswg epithelial yog dab tsi?
Txawm tias muaj ntauTxhua hom epithelial cov ntaub so ntswg 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.

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.
Cov ntaub so ntswg pom nyob qhov twg?
Spongy ntaub so ntswg yog ib hom ntaub so ntswg pom ob leeg hauv cov nroj tsuag thiab tsiaj. Hauv cov nroj tsuag, nws yog ib feem ntawm mesophyll, qhov uas nws tsim ib txheej ntawm palisade hlwb hauv nplooj. Lub spongy mesophyll txoj haujlwm yog tso cai rau kev sib pauv ntawm cov pa roj carbon monoxide (CO2) uas xav tau rau photosynthesis.
Qhov ntswg qhov ntswg yuav tsum nyob qhov twg?
Qhov kev tso ntawm qhov tho yuav tsum yog nyob rau hauv nruab nrab ntawm lub supra-alar crease. Txawm li cas los xij, kev tso kawm tuaj yeem ua rau pem hauv ntej lossis nraub qaum thiab txawm tias hauv qab. Yog tias koj muaj lub siab xav hnav lub nplhaib tab sis koj lub ntsej muag siab ntawm lub qhov ntswg los yog lub nplhaib loj yuav xav tau lossis qhov tho yuav tsum qis dua.
Cov ntaub so ntswg ntom ntom ntom pom nyob qhov twg?
Elastic fibers Elastic fibers Elastic fibers Elastic fibers (los yog daj fibers) yog ib qho tseem ceeb ntawm cov extracellular matrix muaj li ntawm cov pob ntawm cov proteins (elastin) uas yog tsim los ntawm ntau yam sib txawv cell hom xws li fibroblasts, endothelial, cov leeg du, thiab cov hlab ntsha epithelial hlwb.
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.
