During appositional growth, the osteoblasts are depositing osteoid in which location?

|
Osteon
|
|
|
Concentric Lamellae
|
|
|
External Circumferential Lamellae
|
|
|
Medullary Cavity

Explanation:
Detailed explanation-1: -Furthermore, the entire region of calcified spicules becomes surrounded by compact mesenchymal cells that form the periosteum (a membrane that surrounds the bone). The cells on the inner surface of the periosteum also become osteoblasts and deposit osteoid matrix parallel to that of the existing spicules.
Detailed explanation-2: -Appositional growth is the process by which old bone that lines the medullary cavity is reabsorbed and new bone tissue is grown beneath the periosteum, increasing bone diameter.
