pob txha mos yog ib yam ntawm cov ntaub so ntswg sib txuas hauv koj lub cev. Nws muaj cov hlwb hu ua chondrocytes tov nrog collagen thiab qee zaum elastin fibers meshed rau hauv matrix. … Elastic pob txha mos muaj elastin fibers, ua kom nws hloov tau ntau dua li lwm hom pob txha mos.
Vim li cas pob txha mos thiaj muaj zog thiab yoog tau?
Cov protein tseem ceeb yog elastin. Elastic pob txha mos yog histologically zoo ib yam li hyaline pob txha mos tab sis muaj ntau daj elastic fibers dag nyob rau hauv ib tug khoom matrix. Cov fibers no tsim cov pob uas tshwm tsaus nti hauv lub tshuab tsom. Lawv muab cov pob txha mos elastic zoo heev kom nws tuaj yeem tiv taus rov kho dua
pob txha mos hloov tau li cas?
Elastic pob txha yog hloov tau ntau dua uas cov pob txha mos hyaline thiab muaj nyob rau hauv pob ntseg, larynx thiab epiglottis.
Puas pob txha mos muaj qhov yoog tau?
pob txha mos yog cov ntaub so ntswg hloov pauv tau uas txawv ntawm pob txha hauv ntau txoj hauv kev; nws yog avascular thiab nws cov microarchitecture yog tsawg dua cov pob txha. Pob txha mos tsis yog innervated thiab yog li tso siab rau kev nthuav dav kom tau txais cov as-ham.
Cov khoom ntawm pob txha mos yog dab tsi?
Lawv yog ob leeg ua los ntawm cov hlwb embedded nyob rau hauv ib tug extracellular matrix. Nws yog qhov xwm txheej ntawm matrix uas txhais cov khoom ntawm cov ntaub so ntswg sib txuas. Pob txha mos yog nyias, avascular, yoog raws thiab tiv taus lub zog compressive Pob txha yog vascularised heev, thiab nws cov calcified matrix ua rau nws muaj zog heev.
