Qhov Tseem Ceeb Qhov txawv - Yooj yim vs Stratified Epithelial Tissue
Epithelial cov ntaub so ntswg yog ib hom ntaub so ntswg uas tsim cov txheej txheej ntawm lub cev thiab tsim cov kab noj hniav ntawm lub cev. Raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm cov ntaub so ntswg epithelial, cov ntaub so ntswg epithelial muab faib ua ob chav loj; cov ntaub so ntswg yooj yim thiab cov ntaub so ntswg stratified epithelial. Qhov sib txawv tseem ceeb ntawm cov ntaub so ntswg yooj yim thiab stratified epithelial yog tias cov ntaub so ntswg epithelial yooj yim tsuas muaj ib txheej ntawm cov hlwb xwb, hos cov ntaub so ntswg stratified epithelial muaj ob los yog ntau lub cell txheej stacked rau ib leeg.
Cov ntaub so ntswg yooj yim yog dab tsi?
Cov ntaub so ntswg yooj yim epithelial muaj ib txheej ntawm cov hlwb. Cov txheej txheem ntawm cov cell so ntawm ib qho tsis yog cellular hauv qab daim nyias nyias. Lub hauv paus membrane no yog tsim los ntawm ib tug fibrous network. Raws li cov duab ntawm cov hlwb hauv txheej ntawm cov hlwb hauv cov ntaub so ntswg yooj yim, muaj plaub yam tseem ceeb ntawm cov ntaub so ntswg epithelial.
Simple Squamous Epithelial Tissue
Cov ntaub so ntswg squamous epithelial yooj yim yog tsim los ntawm ib txheej ntawm lub tiaj tiaj polygonal lossis hexagonal zoo li lub hlwb. Txhua lub cell muaj qhov chaw nyob hauv nruab nrab, kheej kheej kheej kheej thiab tsis xwm yeem ciam teb. Cov ntaub so ntswg no faib rau hauv ob sab phlu ntawm lub plawv, alveoli, Bowman's capsule, visceral thiab peritoneal hauv ob sab phlu ntawm coelom. Nws lub luag haujlwm tseem ceeb yog kev tiv thaiv, pom, nqus, thiab zais cia.
Simple Cuboidal Epithelial Tissue
Cov ntaub so ntswg no yog tsim los ntawm ib txheej ntawm cuboidal-zoo li lub hlwb nrog tib qhov siab thiab dav. Cov ntaub so ntswg no tau muab faib rau hauv cov ducts thiab qog, uas suav nrog cov kab mob pancreatic thiab cov qog ua kua qaub. Nws kuj raug faib raws lub raum tubule. Yooj yim cuboidal epithelial hlwb kuj tuaj yeem ua kab nrog microvilli uas yuav pab txhawb kev ua haujlwm ntawm kev nqus. Cov haujlwm dav dav yog kev tiv thaiv, nqus, tso tawm, thiab tawm.
Simple Columnar Epithelial Tissue
Cov ntaub so ntswg epithelial no muaj cov kab mob siab-zoo li lub hlwb nrog qhov siab thiab dav tsis sib npaug. Cov hlwb muaj cov nuclei uas yog elongated thiab nyob ze ze rau hauv qab daus daim nyias nyias. Ib qho yooj yim columnar epithelial cov ntaub so ntswg muaj cov kab mob goblet lossis cov cell secretory uas zais ntau yam tshuaj thiab kua dej. Cov ntaub so ntswg yog faib raws li hauv ob sab phlu ntawm lub plab, me me thiab loj txoj hnyuv, digestive qog, ureter, uterine phab ntsa, thiab gallbladder. Lub luag haujlwm tseem ceeb suav nrog kev nqus, tso tawm, thiab tso tawm.
Pseudo Stratified Epithelial Tissue
Cov hlwb ntawm cov ntaub so ntswg pseudostratified epithelial sib txawv hauv qhov siab. Cov ntaub so ntswg epithelial zoo li muaj ntau cov txheej txheem ntawm tes vim tias cov hlwb muaj qhov siab sib txawv. Tsuas yog cov hlwb siab tshaj plaws mus txog qhov chaw tab sis tag nrho cov hlwb nyob rau hauv qab daus daim nyias nyias. Vim qhov kev xav tsis zoo no, cov ntaub so ntswg epithelial yog hu ua pseudostratified. Cov hlwb feem ntau yog ciliated thiab muab faib raws lub trachea, bronchi, thiab lwm yam kev ua pa. Lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau cov plua plav thiab cov kab mob sib kis thiab muab kev tiv thaiv.
Dab tsi yog Stratified Epithelial Tissue?
Cov ntaub so ntswg stratified yog tsim los ntawm ob lossis ntau txheej ntawm cov hlwb thiab yog cov ntaub so ntswg uas dav tshaj plaws hauv cov kab mob hauv nruab nrog cev thiab lub cev kab noj hniav. Cov ntaub so ntswg stratified epithelial kuj categorized raws li cov duab ntawm lub hlwb.
Daim duab 01: Stratified Epithelium
Stratified Squamous Epithelial Tissue
Cov duab ntawm cov hlwb zoo ib yam li cov ntaub so ntswg squamous epithelial yooj yim, tab sis tau teem rau ntau txheej. Cov ntaub so ntswg stratified no tau muab faib ua keratinized thiab nonkeratinized. Keratinized stratified squamous epithelial cov ntaub so ntswg yog faib nyob rau hauv txheej txheej ntawm daim tawv nqaij. Nws muaj cov protein keratin uas muaj kev tiv thaiv kev ua haujlwm. Lwm hom yog hom nonkeratinized. Nws muaj nyob rau hauv lub qhov ncauj kab noj hniav, esophagus mus rau lub plab hlws ris lub qhov quav thiab qhov quav, qhov chaw mos thiab ncauj tsev menyuam.
Stratified Cuboidal thiab Stratified Columnar Epithelial Tissue
Ob hom no yog cov yam ntxwv zoo li hauv cov ntaub so ntswg yooj yim tab sis tau muab tso rau ntawm ntau txheej. Stratified cuboidal muaj nyob rau hauv ducts ntawm cov qog (hws qog, mammary qog). Stratified columnar epithelial yog tam sim no nyob rau hauv qhov chaw hloov pauv (kev sib txuas) ntawm lwm hom epithelial.
Kev hloov pauv ntawm daim tawv nqaij epithelial
Transitional epithelium yog hom stratified epithelial cov ntaub so ntswg. Cov hlwb muaj qhov sib txawv ntawm qhov sib txawv thiab yog ncab raws lub hauv paus membrane. Kev faib tawm yog nyob rau hauv ob sab ntawm lub ureters, urethra, thiab zais zis.
Daim duab 02: Yooj yim thiab stratified epithelial daim ntaub
Dab tsi yog qhov zoo sib xws ntawm cov ntaub so ntswg yooj yim thiab stratified epithelial?
- Lawv yog hom ntaub so ntswg uas tsim cov kab mob hauv nruab nrog cev thiab tiv thaiv lub cev.
- Lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg muaj xws li nqus, tso zis, tso tawm, thiab tiv thaiv.
- Ob cov ntaub so ntswg muaj cov hauv qab daus uas cov hlwb nyob.
- Ob cov ntaub so ntswg muaj ntau hom hlwb raws li cov duab ntawm cov hlwb.
Dab tsi yog qhov sib txawv ntawm cov ntaub so ntswg yooj yim thiab stratified epithelial?

Summary – Yooj yim vs Stratified Epithelial Tissue
Cov ntaub so ntswg yooj yim thiab cov ntaub so ntswg stratified yog ob lub ntsiab ntawm cov ntaub so ntswg epithelial uas tau categorized li raws li cov xov tooj ntawm tes thiab cov duab ntawm tes. Cov ntaub so ntswg epithelial yooj yim tsuas muaj ib txheej ntawm cov hlwb xwb. Lub stratified epithelial cov ntaub so ntswg muaj ob los yog ntau tshaj cell txheej stacked rau ib leeg. Qhov no yog qhov sib txawv ntawm qhov yooj yim thiab stratified epithelial cov ntaub so ntswg. Tag nrho cov ntaub so ntswg epithelial no tsim cov kab mob hauv nruab nrog cev thiab cov kab noj hniav hollow uas ua haujlwm ntau yam ntawm kev tiv thaiv, nqus, tso tawm, thiab tso tawm.
