Cov pob txha ntawm lub cev tsuas muaj pob txha pob txha compact pob txha Compact pob txha (los yog cov pob txha cortical) tsim cov txheej txheem nyuaj sab nraud ntawm tag nrho cov pob txha thiab nyob ib puag ncig lub medullary kab noj hniav, lossis pob txha pob txha.. Nws muab kev tiv thaiv thiab lub zog rau cov pob txha. Cov pob txha pob txha muaj cov chav hu ua osteon lossis Haversian systems. https://courses.lumenlearning.com › structure-of-bones

ntawm lawv qhov chaw sab nrauv thiab tsis tob heev. Cov pob txha feem ntau yog ua los ntawm cov pob txha spongy pob txha Fibroblasts tsim collagen fibers uas txuas cov pob txha tawg, thiab osteoblasts pib tsim cov pob txha spongy. Kev kho cov ntaub so ntswg ntawm cov pob txha tawg yog hu ua fibrocartilaginous callus, raws li nws yog tsim los ntawm ob qho tib si hyaline thiab fibrocartilage (Daim duab 2). Qee cov pob txha spicules kuj tuaj yeem tshwm sim ntawm qhov no. https://courses.lumenlearning.com › wm-biology2 › tshooj

Cov ntaub so ntswg twg pom nyob rau saum npoo ntawm tag nrho cov pob txha quizlet?
TRUE OR FALSE. Hom pob txha (osseous) cov ntaub so ntswg uas muaj feem ntau ntawm cov diaphysis ntawm cov pob txha ntev thiab nyob rau ntawm cov pob txha yog hu ua pob txha pob txha. Hom pob txha uas yog tsim los ntawm cov kab me me ntawm cov pob txha xoob nrog trabeculae yog hu ua_ pob.
Cov ntaub so ntswg twg pom nyob rau saum npoo ntawm cov pob txha hauv cov txheej txheem nruj nreem nyob rau hauv parallel osteons?
Cov khoom ntawm cov ntaub so ntswg pob txha: Cov pob txha pob txha muaj cov osteons uas sib npaug rau cov pob txha ntev thiab cov kwj dej Haversian uas muaj cov pob txha cov hlab ntsha thiab cov hlab ntsha. fibers. Cov pob txha sab hauv muaj cov ntaub so ntswg spongy.
cov pob txha osseous pom nyob qhov twg?
Cov pob txha yog tsim los ntawm cov pob txha pob txha, pob txha pob txha, thiab cov pob txha pob txha. Cov pob txha pob txha ua rau txheej txheej ntawm cov pob txha. Cov pob txha pob txha feem ntau pom ntawm qhov kawg ntawm cov pob txhathiab muaj cov pob txha liab. Cov pob txha muaj nyob hauv nruab nrab ntawm cov pob txha feem ntau thiab muaj ntau cov hlab ntsha.
Yuav ua li cas cov ntaub so ntswg yog pob txha osseous cov ntaub so ntswg muaj li ntawm?
pob txha (osseous cov ntaub so ntswg) yog cov ntaub so ntswg tawv, ib hom kev sib txuas tshwj xeeb. Nws muaj honeycomb zoo li matrix sab hauv, uas pab muab cov pob txha rigidity. Cov pob txha yog tsim los ntawm ntau hom pob txha.

Dab tsi ua kom pob txha pob txha ntawm cov pob qij txha?
pob txha muab cov duab, txhawb nqa, thiab qauv rau lwm cov ntaub so ntswg hauv lub cev. Nws kuj yuav pab tau cov pob qij txha. Pob txha mos kuj smoothens cov pob txha nto ntawm cov pob qij txha. Cov ntaub so ntswg dab tsi npog cov pob txha ntawm cov pob qij txha?
Puas yog pob txha pob txha pob txha zoo ib yam li meniscus?
Cov pob txha mos yog qhov tawv tab sis du npog ntawm qhov kawg ntawm cov pob txha hauv cov pob qij txha. Nws tso cai rau gliding yam tsis muaj kev tiv thaiv ntau thiab ua haujlwm nrog cov meniscus kom cushion kawg ntawm cov pob txha. Lub meniscus nyob nruab nrab ntawm lub femur thiab tibia.
Dab tsi qhov sib txawv ntawm cov pob txha pob txha thiab pob txha?
Cov pob txha pob txha yog tsim los ntawm osteons thiab tsim cov txheej txheem sab nraud ntawm txhua pob txha. Cov pob txha pob txha yog tsim los ntawm trabeculae thiab ua rau sab hauv ntawm txhua pob txha. Dab tsi yog qhov sib txawv ntawm cov pob txha pob txha thiab pob txha pob txha?
Puas yog lub pob txha pob txha pob txha pob txha?
CONCLUSIONS: vertebral endplate raug mob feem ntau pom hauv osteoporotic vertebral compression fractures. Dab tsi ua rau lub pob txha tawg? Nws yog kev xav tias, nyob rau hauv ntau qhov mob ntawm qhov mob qis qis, thawj qhov ua rau mob yog pob txha ntawm pob txha caj qaum los ntawm compression rog.
Vim li cas pob txha pob txha txawv ntawm cov pob txha li niaj zaus?
Thaum osteoporosis tshwm sim, lub qhov thiab qhov chaw hauv lub honeycomb loj dua li cov pob txha noj qab haus huv. Cov pob txha osteoporotic muaj poob ntom lossis loj thiab muaj cov ntaub so ntswg txawv txav. Raws li cov pob txha tsis tshua muaj zog, lawv tsis muaj zog thiab feem ntau yuav tawg.
