Qhov sib txawv tseem ceeb ntawm qhov yooj yim thiab cov khoom sib xyaw epithelium yog qhov yooj yim epithelium muaj ib txheej ntawm cov hlwb thaum cov txheej txheem epithelium muaj ntau tshaj ib txheej ntawm tes.
Muaj plaub hom ntaub so ntswg hauv peb lub cev uas ua haujlwm sib txawv. Ntawm lawv, lub epithelium yog ib qho tseem ceeb cov ntaub so ntswg uas kab peb lub cev nto thiab sab hauv thiab sab nrauv ntawm lub cev. Muaj ob lub ntsiab ntawm cov ntaub so ntswg epithelial raws li tus naj npawb ntawm cov txheej txheem ntawm tes. Lawv yog cov yooj yim epithelium thiab compound los yog stratified epithelium. Ib qho yooj yim epithelium yeej ib txwm muaj ib txheej cell thaum compound epithelium muaj ntau tshaj ib txheej cell. Li no, muaj qhov sib txawv ntawm qhov yooj yim thiab compound epithelium hais txog cov qauv, kev ua haujlwm, thiab qhov chaw.
YDab tsi yog Epithelium yooj yim?
Yooj yim epithelium yog ib qho ntawm ob hom tseem ceeb ntawm cov ntaub so ntswg epithelial. Raws li lub npe qhia, qhov yooj yim epithelium muaj ib txheej cell. Yog li ntawd, tag nrho cov hlwb ntawm cov epithelium yooj yim yog txuas mus rau hauv qab daus daim nyias nyias. Raws li cov duab ntawm cov hlwb, muaj plaub hom ntawm cov epithelium yooj yim li squamous epithelium, yooj yim cuboidal epithelium, yooj yim columnar epithelium, thiab pseudo-stratified epithelium.
Daim duab 01: Yooj Yim Epithelium
Tsis tas li ntawd, cov ntaub so ntswg yooj yim tuaj yeem pom nyob rau hauv cov hlab ntsha, alveoli, pericardium, raum tubules, pancreas, qog, plab, hnyuv me, trachea, pa, thiab qhov ntswg. Yooj yim epithelium tsuas yog ua tiav cov haujlwm xws li nqus, tso tawm, thiab pom.
Dab tsi yog Compound Epithelium?
Compound epithelium lossis stratified epithelium yog hom thib ob loj ntawm cov ntaub so ntswg epithelial. Nws muaj ntau tshaj ib txheej cell. Yog li ntawd, tsuas yog qhov tob tshaj plaws ntawm cov txheej txheem epithelium yog txuas rau hauv qab daus daim nyias nyias. Tsis tas li ntawd, qhov sib xyaw epithelium tuaj yeem ua keratinized. Zoo ib yam li cov epithelium yooj yim, cov txheej txheem epithelium tuaj yeem ua tau squamous stratified, cuboidal stratified, columnar stratified lossis transitional epithelium.
Daim duab 02: Compound Epithelium
Compound epithelium feem ntau ua tiav kev tiv thaiv kev ua haujlwm. Yog li ntawd, peb tuaj yeem soj ntsuam lawv hauv txoj hlab pas, qhov ncauj, qog hws, qog mammary, txiv neej urethra, tawv nqaij, thiab zais zis.
Dab tsi yog qhov zoo sib xws ntawm Yooj Yim thiab Cov Khoom Siv Epithelium?
- Yooj yim thiab sib xyaw epithelium yog ob hom epithelial cov ntaub so ntswg.
- Lawv so rau hauv qab daus membrane.
- Tsis tas li, ob daim ntaub so ntswg muaj cov hlwb nyob.
- Thiab, cov ntaub so ntswg tuaj yeem faib ua squamous, cuboidal lossis columnar los ntawm cov duab.
- Tsis tas li ntawd, lawv tsis muaj cov hlab ntsha.
- Yog li, lawv tau txais khoom noj los ntawm kev sib kis los ntawm cov ntaub so ntswg hauv qab hauv qab daim nyias nyias.
- Cov ntaub so ntswg epithelial kab sab hauv thiab sab nraud ntawm lub cev thaum muab kev tiv thaiv.
Dab tsi yog qhov txawv ntawm Yooj Yim thiab Cov Khoom Siv Epithelium?
Qhov sib txawv tseem ceeb ntawm qhov yooj yim thiab cov khoom sib xyaw epithelium nyob hauv cov xov tooj ntawm tes. Qhov ntawd yog; Qhov yooj yim epithelium muaj ib txheej cell thaum compound epithelium muaj ntau tshaj ib txheej cell. Ntxiv mus, qhov sib txawv ntawm qhov yooj yim thiab compound epithelium yog tias cov epithelium yooj yim ua haujlwm xws li nqus, tso tawm, thiab pom thaum cov khoom siv epithelium muaj kev tiv thaiv.
Tsis tas li ntawd, muaj plaub yam ntawm cov ntaub so ntswg yooj yim xws li squamous, cuboidal, columnar thiab pseudo-stratified epithelium thiab plaub hom compound epithelial cov ntaub so ntswg ua squamous, cuboidal, transitional thiab columnar. Li no, peb tuaj yeem xav txog qhov no kuj yog qhov sib txawv ntawm qhov yooj yim thiab compound epithelium. Ib qho sib txawv ntxiv ntawm qhov yooj yim thiab compound epithelium yog qhov txuas rau hauv qab daus daim nyias nyias. Nyob rau hauv yooj yim epithelium, tag nrho cov cell txuas mus rau hauv qab daus daim nyias nyias. Txawm li cas los xij, hauv qhov sib xyaw epithelium, tsuas yog txheej txheej tob tshaj plaws txuas rau hauv qab daus daim nyias nyias.
Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm qhov yooj yim thiab cov khoom sib xyaw epithelium piv.
Summary – Yooj yim vs Compound Epithelium
Yooj yim thiab sib xyaw epithelium yog ob hom tseem ceeb ntawm cov ntaub so ntswg epithelial. Lub epithelium yooj yim muaj ib txheej ntawm tes thaum cov khoom sib xyaw epithelium muaj ntau tshaj ib txheej ntawm tes. Yog li, qhov no yog qhov sib txawv ntawm qhov yooj yim thiab compound epithelium. Ntxiv mus, tag nrho cov hlwb ntawm cov epithelium yooj yim yog txuas mus rau hauv qab daus daim nyias nyias thaum nyob rau hauv lub compound epithelium, tsuas yog lub deepest cell txheej yog txuas mus rau hauv qab daus daim nyias nyias. Tsis tas li ntawd, cov epithelium yooj yim ua tiav cov haujlwm xws li nqus, pom, thiab tso tawm thaum lub sijhawm sib xyaw epithelium ua tiav cov haujlwm tiv thaiv. Yog li, qhov no qhia txog qhov sib txawv ntawm qhov yooj yim thiab compound epithelium.
