osteon
1
the bony matrix that runs around the bone

Circumferential lamellae
1
collagen or perforating fibers

Sharpey’s fibers
1
a fibrous membrane covering made of dense irrecgular connective tissue
1
periosteum
1
runs parallel to the long axis of the bone and carries blood vessels, nerves, and lymphatic vessels throught the bony matrix

central canal

chambers within the bony matrix
1
lacuna
1
mature bone cells
1
osteocytes
1
tiny canals radiating outward from a central canal to the lacunae of the first lamella and then from lamella to lamella; forms a dense transportation network through the hard bone matrix
