Cov ntshav muab rau cov pob txha yog xa mus rau cov kab noj hniav endosteal los ntawm cov hlab ntsha, ces ntws los ntawm pob txha sinusoids ua ntej tawm ntawm ntau cov hlab ntsha me me uas ramify los ntawm cortex.

Kuj tseem paub yog, dab tsi yog cov khoom noj khoom haus ntawm cov hlab ntsha?

Cov diaphysis thiab metaphysis tau txhawb nqa feem ntau los ntawm cov hlab ntsha , uas dhau los ntawm lub cortex mus rau hauv lub medullary kab noj hniav thiab ces ramifies sab nraud los ntawm haversian thiab Volkmann kwj dej mus rau khoom lub cev.

Tsis tas li, cov pob txha puas muaj cov hlab ntsha? Skeleton Feem ntau cov pob txha muaj lub hauv paus tseem ceeb cov leeg thiab cov hlab ntsha uas nkag mus rau thaj tsam nruab nrab ntawm cov ncej los ntawm qhov hu ua cov khoom noj khoom haus, tab sis cov hlab ntsha kuj nkag mus rau hauv cov hlab ntsha. pob txha hauv lwm qhov chaw, tshwj xeeb tshaj yog nyob rau ob sab ntawm kab epiphyseal.

Ntxiv mus, qhov twg cov as -ham cov ntshav nkag mus rau pob txha?

Cov cov hlab ntsha (arteria nutricia) lossis nruab nrab, feem ntau nrog ib lossis ob leeg leeg, nkag cov pob txha dhau ntawm as -ham foramen, khiav obliquely los ntawm lub cortex, xa ceg upward thiab downward rau lub pob txha pob txha, uas ua rau lub raum nyob rau hauv endosteum, vascular membrane sab hauv nruab nrab kab noj hniav, thiab muab

Cov pob txha trabecular tau txais cov khoom noj li cas?

Cov pob txha cov ntaub so ntswg ua tsis muaj osteons. Hloov chaw, nws suav nrog trabeculae , uas yog lam tias yog teem raws li rods los yog daim hlau. Liab pob txha pob txha yog pom ntawm trabuculae. Cov hlab ntsha hauv cov ntaub so ntswg xa mus cov as-ham rau osteocytes thiab tshem tawm cov pov tseg.
