Cov av hauv av , zoo li amorphous gel khoom tam sim no nyob rau hauv muaj pes tsawg leeg ntawm ntau cov ntaub so ntswg sib txuas. Nws yog qhov tseeb tshaj plaws pom hauv pob txha mos, hauv qhov kev lom zem ntawm lub qhov muag, thiab hauv Wharton's jelly ntawm txoj hlab ntaws.

Tsis tas li, dab tsi yog cov khoom hauv av thiab nws pom qhov twg?

Cov av hauv av yog amorphous gel zoo li khoom nyob rau hauv qhov chaw seem sab nraud uas suav nrog txhua yam khoom siv ntawm cov txheej txheem sab nrauv (ECM) tshwj tsis yog cov khoom siv fibrous xws li collagen thiab elastin. GAGs yog polysaccharides uas ntxiab dej, muab cov hauv av kev ntxhib los mos zoo li gel.

Ib tus kuj yuav nug, qhov twg yog cov khoom hauv av hauv cov ntaub so ntswg adipose? Lawv tau pom thoob plaws hauv lub cev, tab sis muaj ntau tshaj nyob hauv cov reticular cov ntaub so ntswg ntawm cov kab mob hauv lub cev, xws li daim siab thiab tus po, qhov uas lawv thauj tog rau nkoj thiab muab cov qauv kev txhawb nqa rau parenchyma (cov qog ua haujlwm, cov hlab ntshav, thiab lub paj hlwb ntawm lub cev). Txhua yam ntawm cov hom fiber no tau teeb tsa cov khoom hauv av.

Cov lus nug tseem yog, cov khoom hauv av suav nrog dab tsi?

'Cov khoom hauv av' ntawm extracellular matrix yog amorphous gelatinous khoom. Nws yog pob tshab, tsis muaj xim, thiab ua kom pom qhov chaw nruab nrab ntawm cov fibers thiab cov cell. Nws yeej muaj cov molecules loj hu ua glycosoaminoglycans (GAGs) uas txuas ua ke los tsim cov molecules loj dua hu ua proteoglycans.

Qhov twg ntawm fibrocartilage muaj cov khoom hauv av?

Cov matrix feem ntau yog acidophilic vim muaj ntau ntawm collagen (hom I) fibers. Cov hauv av nruab nrab ntawm cov fibers yog basophilic thiab muaj chondroblasts/cytes hauv lacunae. Fibrocartilage tsis muaj ib perichondrium.
