How Do Interstitial Lamellae Differ from Circumferential Lamellae?
While interstitial lamellae are remnants of old osteons located between new osteons, circumferential lamellae are layers of bone tissue that encircle the outer and inner surfaces of the bone. Circumferential lamellae provide additional structural support and are found just beneath the periosteum (outer layer) and around the medullary cavity (inner layer).
