What type of lamellae wrap around the ENTIRE bone?

Explanation:
Circumferential lamellae wrap around the entire bone. They form outer rings beneath the periosteum and inner rings against the endosteum, effectively outlining the bone’s circumference. This arrangement helps the bone resist stresses from all directions around its outer surface and accommodates growth in diameter. Concentric lamellae, by contrast, form rings around a central canal inside an osteon, not around the whole bone. Interstitial lamellae are remnants between osteons, not complete circumference rings. Perforating lamellae run across the bone to connect osteons, not encircle the whole bone.
