Cov osteoclasts yog ntau lub nucleated hlwb uas muaj ntau mitochondria thiab lysosomes. Cov no yog cov hlwb ua lub luag haujlwm rau resorption ntawm pob txha. Osteoclasts feem ntau muaj nyob rau txheej txheej ntawm cov pob txha, tsuas yog hauv qab lub periosteum.
pob txha reabsorbing hlwb hu ua dab tsi?
Osteoblasts thiab Osteocytes: cov no yog cov pob txha tsim cov hlwb. Osteoclasts: cov no yog cov pob txha resorbing hlwb.
Yuav ua li cas yog cov pob txha?
pob txha muaj plaub hom cell sib txawv; osteoblasts, osteocytes, osteoclasts thiab pob txha hauv cov hlwb. Osteoblasts, pob txha hauv cov hlwb thiab osteoclasts muaj nyob rau ntawm pob txha pob txha thiab tau muab los ntawm cov hlwb mesenchymal hauv zos hu ua progenitor cells.
Yuav ua li cas hauv qab no yog pob txha reabsorbing cell lov pob txha)?
Osteoblasts yog cov pob txha tsim cov hlwb, osteocytes yog cov pob txha paub tab thiabosteoclaststawg thiab rov nqus cov pob txha. Muaj ob hom ossification: intramembranous thiab endochondral.
Yuav ua li cas hauv qab no yog pob txha rhuav tshem cov pob txha?
Osteoclasts tso tawm cov enzyme uas rhuav tshem cov pob txha thaum pom tias tsim nyog. Cov hlwb no yog ib feem tseem ceeb ntawm cov pob txha loj hlob thiab kho pob txha. Nws kuj tseem pab txhim kho cov pob txha thaum nws puas. Monocytes, ib hom qe ntshav dawb, ua ke los tsim osteoclasts.
