yooj yim columnar epithelium
Ib yam nkaus, qhov sib txawv ntawm cov nqaij mos epithelial nyob qhov twg?
Hom Epithelial Tissue
| Epithelial Tissue Cells | |
|---|---|
| Xovtooj | Qhov chaw |
| Stratified cuboidal epithelium | Cov qog tawm hws, qog ua kua qaub, thiab qog qog |
| Stratified columnar epithelium | Txiv neej cov zis thiab cov ducts ntawm qee cov qog. |
| Transitional epithelium | Ua kom lub zais zis, cov zis thiab cov ureters |
Ib tus kuj tseem yuav nug tau, hom ntaub so ntswg epithelial tuaj yeem pom hauv lub zais zis? transitional epithelium
Ib yam li ntawd, nws tau nug, hom ntaub so ntswg epithelial tuaj yeem pom hauv lub ntsws?
Feem ntau ntawm txoj kev ua pa, los ntawm lub qhov ntswg kab noj hniav los ntawm lub ntsws, yog kab los ntawm ciliated, Pseudostratified columnar epithelium nrog goblet hlwb. Bronchioles yog lined los ntawm yooj yim cuboidal epithelium. (Lub ntsws alveoli, hauv qhov sib piv, tau hlua los ntawm qhov nyias nyias yooj yim squamous epithelium.)
Koj nyob qhov twg hauv txoj hnyuv koj yuav pom cov ntaub so ntswg epithelial?
Kev tiv thaiv mucosa yog tus cwj pwm los ntawm stratified squamous epithelium cov ntaub so ntswg . Nws yog pom nyob rau hauv lub qhov ncauj kab noj hniav, pharynx, esophagus, thiab qhov quav kwj dej. Lub zais zis mucosa muaj cov cell uas yog lub luag hauj lwm rau lub secretion ntawm plab cov enzymes. Nws yog pom tshwj xeeb hauv plab.

Dab tsi yog qhov sib txawv ntawm cov ntaub so ntswg sib txuas tsis tu ncua thiab cov ntaub so ntswg sib txuas tsis sib xws?
Cov ntaub so ntswg sib txuas tsis sib thooj muaj cov fibers uas tsis tau sib dhos ua ke zoo ib yam li cov ntaub so ntswg sib txuas ib ntus. Cov ntaub so ntswg sib txuas tsis sib thooj muaj feem ntau ntawm cov fibers collagen. Nws muaj cov khoom hauv av tsawg dua li cov ntaub so ntswg sib txuas
Dab tsi ntawm cov ntaub so ntswg epithelial yog lub epidermis ntawm daim tawv nqaij?
Stratified squamous epithelium
Dab tsi yog cov yam ntxwv ntawm cov ntaub so ntswg epithelial?
Txawm hais tias muaj ntau hom sib txawv ntawm cov nqaij mos epithelial txhua cov ntaub so ntswg epithelial tsuas muaj tsib yam ntxwv, cov no yog cellularity, polarity, txuas, vascularity, thiab rov tsim dua tshiab. Cellularity raws li lub npe qhia txhais tau tias epithelium tau tsim los yuav luag tag nrho ntawm cov cell
Qhov twg ntawm cov hauv qab no yog kev ua haujlwm ntawm cov ntaub so ntswg epithelial?
Kev ua haujlwm ntawm cov hlwb epithelial suav nrog kev zais cia, xaiv qhov nqus, tiv thaiv, kev thauj mus los, thiab kev hnov. Cov txheej epithelial tsis muaj cov hlab ntshav, yog li lawv yuav tsum tau txais kev txhawb nqa los ntawm kev nthuav tawm cov tshuaj los ntawm cov ntaub so ntswg sib txuas, los ntawm cov hauv qab daus
Lub npe ntawm cov pob txha pob txha pom nyob rau hauv cov ntaub so ntswg osseous yog dab tsi?
Osteocytes, cov hlwb nyob ntawm cov pob txha cov ntaub so ntswg, tsim cov ntxhia matrix ntawm cov pob txha. Muaj ob hom nqaij pob txha: compact thiab spongy
