Kev cog pob txha (los yog cortical pob txha ) tsim cov txheej sab nraud nyuaj ntawm txhua pob txha thiab nyob ib puag ncig kab noj hniav nruab nrab, lossis pob txha pob txha. Nws muab kev tiv thaiv thiab lub zog rau pob txha . Kev cog pob txha cov ntaub so ntswg muaj cov chav hu ua osteons lossis Haversian systems.
Los ntawm nws, dab tsi yog cov qauv ntawm cov pob txha compact?
Cov pob txha pob txha muaj cov osteons zoo sib xws los yog haversian systems. Lub pob txha muaj ntawm lub hauv nruab nrab cov kwj dej hu ua osteonic (haversian) kwj dej, uas nyob ib puag ncig los ntawm cov nplhaib sib xyaw (lamellae) ntawm matrix . Nruab nrab ntawm cov rings ntawm matrix ,i luj hlwb (osteocytes) nyob hauv qhov chaw hu ua lacunae.
Ib qho ntxiv, dab tsi yog ob yam ntxwv ntawm cov pob txha compact? Kev cog pob txha. Cov pob txha pob txha, tseem hu ua pob txha cortical, cov pob txha ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom pob txha pob txha pob txha pob txha pob txha, tseem hu ua pob txha pob txha cortical, cov pob txha ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom pob txha pob txha uas cov pob txha matrix tau ntim nrog cov khoom siv hauv av thiab cov ntsev inorganic ntsev, tsuas yog qhov chaw me me (lacunae) uas muaj cov osteocytes, lossis pob txha. hlwb.
Ib yam li ntawd, koj tuaj yeem nug, qhov pom pob txha nyob qhov twg?
Pob txha Compact Nws tuaj yeem yog pom nyob rau hauv lub periosteum thiab nyob rau hauv lub diaphyses ntawm ntev pob txha , qhov twg nws muab kev txhawb nqa thiab kev tiv thaiv. Microscopic structural unit ntawm pob txha compact hu ua osteon, lossis Haversian system.
Dab tsi yog chav tsev yooj yim ntawm cov pob txha compact?
Cov qauv me me unit ntawm cov pob txha compact hu ua osteon, lossis Haversian system. Txhua lub pob txha yog tsim los ntawm cov nplhaib sib xyaw ntawm calcified matrix hu ua lamellae (singular = lamella).

Dab tsi yog lub luag haujlwm ntawm pob txha pob txha?
Lub luag haujlwm tseem ceeb ntawm cov pob txha yog kev txhawb nqa lub cev, txhawb kev txav chaw, tiv thaiv lub cev sab hauv, khaws cov zaub mov thiab rog, thiab hematopoiesis. Ua ke, cov leeg nqaij thiab lub cev pob txha hu ua lub cev musculoskeletal
Dab tsi yog CPT txoj cai los tshaj tawm cov pob txha pob txha xav tau ua rau pob txha pob txha thaum phais pob txha?
Pib 01/01/18, CPT code 20939 yuav tsum tau siv los tshaj tawm cov pob txha pob txha xav tau rau pob txha pob txha hauv kev phais pob txha
Cov pob txha twg yog cov pob txha compact?
Cov pob txha sib cog ua ib lub plhaub nyob ib ncig ntawm cov pob txha uas raug tshem tawm thiab yog thawj feem ntawm cov pob txha ntev ntawm caj npab thiab txhais ceg thiab lwm cov pob txha, qhov twg nws xav tau lub zog ntau dua thiab nruj. Cov pob txha loj hlob tuaj yog lamellar, lossis txheej, hauv cov qauv
Cov pob txha pob txha thiab pob txha ua haujlwm li cas thiaj txav tau lub cev?
Cov nqaij ntshiv lub cev los ntawm kev cog lus tawm tsam cov pob txha. Thaum cov leeg mob, lawv tau luv. Los ntawm kev cog lus, cov leeg rub ntawm cov pob txha thiab cia lub cev txav mus los
Dab tsi ntawm cov pob txha ntawm tes yog lub luag haujlwm rau pob txha?
Kev kho pob txha yog ua kom ntseeg tau los ntawm ob hom cell: osteoclasts, uas resorb cov pob txha calcified matrix, thiab osteoblasts, uas yog lub luag haujlwm rau cov pob txha matrix tshiab. Thaum lub sij hawm kev loj hlob, cov pob txha tsim tshaj cov pob txha resorption, ua rau cov pob txha expansion
