Qhov sib txawv ntawm qhov yooj yim squamous thiab yooj yim cuboidal yog qhov yooj yim squamous cov ntaub so ntswg yog tsim los ntawm ib txheej ntawm ca polygonal los yog hexagonal zoo li lub hlwb thaum cov ntaub so ntswg yooj yim cuboidal yog tsim los ntawm ib txheej ntawm cuboidal zoo li lub hlwb nrog tib qhov siab. thiab dav.
Lub epithelium yog ib qho ntawm plaub hom ntaub so ntswg uas kab peb lub cev nto thiab sab hauv thiab sab nraud 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. 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. Cov ntaub so ntswg yooj yim tuaj yeem pom nyob rau hauv ob sab ntawm 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. Raws li cov duab ntawm cov hlwb, cov epithelium yooj yim muaj plaub yam xws li squamous epithelium, yooj yim cuboidal epithelium, yooj yim columnar epithelium thiab pseudo-stratified epithelium.
Squamous yog dab tsi?
Cov ntaub so ntswg yooj yim squamous epithelial yog tsim los ntawm ib txheej ntawm lub tiaj tiaj polygonal lossis hexagonal zoo li lub hlwb. Txhua lub xovtooj muaj qhov chaw nyob hauv nruab nrab, kheej kheej kheej kheej thiab tsis xwm yeem ciam teb.
Daim duab 01: Simple Squamous
Ntxiv mus, cov ntaub so ntswg no tau muab faib rau hauv ob sab phlu ntawm lub plawv, alveoli, bowman's capsule, visceral thiab peritoneal hauv ob sab phlu ntawm coelom. Tsis tas li, nws lub luag haujlwm tseem ceeb yog kev tiv thaiv, pom, nqus thiab tso tawm.
Cuboidal yooj yim yog dab tsi?
Cov ntaub so ntswg yooj yim yog tsim los ntawm ib txheej ntawm cuboidal zoo li lub hlwb nrog tib qhov siab thiab dav. Tsis tas li ntawd, cov ntaub so ntswg no tau muab faib rau hauv cov ducts thiab qog, uas suav nrog cov kab mob pancreatic thiab cov qog qaub ncaug. Nws kuj raug faib raws lub raum tubule.
Daim duab 02: Yooj Yim Cuboidal
Ntxiv mus, cov kab mob yooj yim cuboidal epithelial kuj tseem 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 tso tawm.
Dab tsi yog qhov zoo sib xws ntawm Yooj Yim Squamous thiab Yooj Yim Cuboidal?
- Simple squamous thiab yooj yim cuboidal epithelia yog ob hom yooj yim epithelial cov ntaub so ntswg uas muaj ib txheej cell.
- Txhua lub hlwb ntawm ob lub epithelia txuas rau hauv qab daus daim nyias nyias.
- Lawv ua haujlwm xws li kev tiv thaiv, nqus, zais cia.
Qhov txawv ntawm Yooj Yim Squamous thiab Yooj Yim Cuboidal yog dab tsi?
Simple squamous yog ib hom ntawm cov epithelium yooj yim tsim los ntawm ib txheej txheej ntawm cov cell uas flattened, thaum yooj yim cuboidal yog ib hom ntawm cov epithelium yooj yim tsim los ntawm ib txheej ntawm cov hlwb uas muaj tib qhov siab thiab dav. Yog li, qhov no yog qhov txawv ntawm qhov yooj yim squamous thiab yooj yim cuboidal.
Ntxiv mus, qhov yooj yim squamous epithelium muaj nyob rau hauv cov phab ntsa ntawm capillaries, linings ntawm pericardial, pleural, thiab peritoneal kab noj hniav, linings ntawm lub alveoli ntawm lub ntsws. Meanwhile, qhov yooj yim cuboidal epithelium yog pom nyob rau hauv sau ducts ntawm lub raum, pancreas, thiab salivary caj pas. Tsis tas li ntawd, kev tiv thaiv, pom, nqus thiab tso tawm yog cov haujlwm yooj yim ntawm squamous epithelium. Lub caij no, kev tiv thaiv, nqus, tso tawm thiab tso tawm yog cov haujlwm yooj yim ntawm cuboidal epithelium.
Hauv qab infographic qhia txog qhov sib txawv ntawm qhov yooj yim squamous thiab yooj yim cuboidal.
Summary – Yooj Yim Squamous vs Simple Cuboidal
Simple squamous thiab yooj yim cuboidal yog ob hom ntawm cov ntaub so ntswg yooj yim. Ob leeg yog tsim los ntawm ib txheej ntawm tes. Cov hlwb squamous yooj yim yog cov hlwb dav thiab tiaj tus. Nyob rau hauv sib piv, yooj yim cuboidal cov ntaub so ntswg hlwb muaj tib qhov dav thiab qhov siab. Cov ntaub so ntswg yooj yim pom muaj nyob rau hauv cov phab ntsa ntawm cov hlab ntsha, cov ntaub so ntswg ntawm lub pericardial, pleural, thiab peritoneal kab noj hniav, linings ntawm lub alveoli ntawm lub ntsws thaum cov ntaub so ntswg yooj yim pom nyob rau hauv pancreatic ducts thiab salivary qog. Yog li, qhov no qhia txog qhov sib txawv ntawm qhov yooj yim squamous thiab yooj yim cuboidal.
