Compact bone, found in the diaphysis in long bone, is organized from outer circumferential lamellae, inner circumferential lamellae, the Haversian systems, and interstitial lamellae. The bone is enveloped by a specialized dense connective tissue, periosteum. The outer circumferential lamellae are composed of several layers of lamellae that are parallel with the surface of the bone, located beneath the periosteum.
