Cancellous pob txha, tseem hu ua pob txha trabecular lossis spongy pob txha, lub teeb, pob txha ntxeem tau ntim ntau qhov chaw loj uas ua rau lub ntsej muag honeycombed lossis spongy zoo li. Cov pob txha matrix, los yog lub moj khaum, yog npaj rau hauv peb-dimensional latticework ntawm cov txheej txheem pob txha, hu ua trabeculae, teem raws kab ntawm kev ntxhov siab.
Cov pob txha twg yog trabecular?
qauv. Cov pob txha trabecular, tseem hu uapob txha pob txha, yog cov pob txha ntxeem tau tsim los ntawm cov pob txha trabeculated. Nws tuaj yeem pom nyob rau ntawm qhov kawg ntawm cov pob txha ntev zoo li lub femur, qhov twg cov pob txha yeej tsis muaj zog tab sis yog tag nrho ntawm qhov txuas los ntawm cov pas nrig nyias thiab daim hlau ntawm cov pob txha.
Puas yog pob txha trabecular tib yam li pob txha woven?
thawj hom pob txha tsim kev loj hlob yog thawj lossis woven pob txha (tsis paub). … Cov pob txha thib ob tau muab faib ua ob hom: pob txha trabecular (tseem hu ua pob txha txhav lossis pob txha pob txha) thiab pob txha pob txha (tseem hu ua pob txha ntom lossis cortical).
Vim li cas pob txha trabecular hu ua spongy?
Cov pob txha tshem tawm kuj tseem hu ua pob txha pob txha vim nws zoo li daim txhuam cev lossis honeycomb, muaj ntau qhov chaw qhib txuas nrog cov dav hlau tiaj tus ntawm cov pob txha hu ua trabeculae. Nyob rau hauv lub trabeculae muaj peb hom pob txha hlwb: osteoblasts, osteocytes thiab osteoclasts.
Dab tsi yog qhov txawv ntawm trabecular thiab cortical pob txha?
Cov khoom siv ntawm cov pob txha sib txawv:pob txha trabecular muaj cov ntsiab lus calcium tsawg thiab cov dej ntau dua piv rau cov pob txha cortical. Cov pob txha trabecular muaj qhov loj ntawm cov pob txha pob txha thiab cov ntshav ntws, thiab qhov kev hloov pauv yog siab dua hauv cov pob txha cortical [1].
