Blood supply to long bones?

Question

How do long bones receive blood supply, then trace the path of the blood delivery to the osteocytes. Anyone?

Answer 1

Long bones are supplied by the nutricious artery,wich penetrates the periostium and ussualy gets into the the bone marrowcavity to spread across the trabecular bone. before it gets there, arteriolar and capilar branches distribute along the cortical bone through the structures calles osteones, made of concentric sheats of osteoid tissue created by the osteoblasts,wich become osteocites and take tehir place between sehat and shata, creating concentric lines of osteocytes, wich are kept in spaces called osteoplasts or lacunae. Because the matrix is too rigid to allow nutrients to freely difuse , the osteocytes comunicate each other by cellular prolongations that go through very small tubes in the laminae called canalicules. These canalicules also serve as a mean to reach the nutrients that bring the capillaries in the osteones.

Answer 3

Haversian and Voelkmann's canals are the vessels that direct blood flow to the osteocytes
