los yog hauv qab daus daim nyias nyias uas cais cov hlwb epithelial los ntawm cov ntaub so ntswg hauv qab.
Puas tag nrho cov hlwb epithelial muaj ib daim nyias nyias?
Basement membrane Page 19 Tag nrho cov epithelia nyob rau hauv qab daus daim nyias nyias. Tag nrho cov hlwb epithelial txuas rau ntawm lawv qhov chaw basal mus rau hauv qab daus daim nyias nyias. Lub hauv qab daim nyias nyias muab qee qhov kev txhawb nqa raws li nws txuas ua ke ib daim ntawv ntawm cov hlwb epithelial.
Dab tsi yog qhov chaw hauv qab daus ntawm cov ntaub so ntswg epithelial?
Lub hauv qab daim nyias nyias, lossis basal lamina, yog ib daim ntawv ntawm cov protein thiab lwm yam khoom uas cov hlwb epithelial adhere thiab uas ua rau muaj kev cuam tshuam ntawm cov ntaub so ntswg.
Cov ntaub so ntswg dab tsi muaj lub hauv paus membrane?
Basement membranes yog ib daim ntawv tshwj xeeb ntawm extracellular matrix uas nyob ib puag ncig epithelial, endothelial, peripheral paj hlwb, nqaij, thiab cov hlwb rog thoob plaws hauv lub cev.
Yuav ua li cas cov ntaub so ntswg tsis muaj hauv qab daus membrane?
cov ntaub so ntswg epithelial ze likiag li avascular. Piv txwv li, tsis muaj cov hlab ntsha hla lub hauv paus membrane nkag mus rau hauv cov ntaub so ntswg, thiab cov as-ham yuav tsum los ntawm diffusion los yog nqus los ntawm cov ntaub so ntswg los yog nto. Cov ntaub so ntswg epithelial tseem innervated los ntawm cov hlab ntsha.
