The Process by Which Osteoblasts Add Layers to Circumferential Lamellae

Question

The process by which osteoblasts add layers to circumferential lamellae is
A) appositional growth.
B) interstitial growth.
C) intramembranous growth.
D) endochondral ossification.
E) epiphyseal ossification.

Accepted Answer

Appositional growth is a process by which osteoblasts add layers to the circumferential lamellae of bones. This causes the bone to increase in diameter or thickness over time. This occurs mainly in compact bone, where the osteoblasts are located in the periosteum.
