Compact bone is composed of thin layers or lamellae of bone and form an osteon Organized lamellae greatly increases the strength of bone Lamellae also are organized as outer and inner circumferential lamellae Lacunae contain one osteocyte which interconnects with others through processes within canaliculi; osteocytes are supplied by vessels in the central canal Central canals communicate with marrow cavity, periosteum, and each other via transverse Volkmann’s (aka perforating) canals
