During Appositional Growth Osteoclast Destroy Bone at the?

Appositional growth is the increase in the diameter of bones by the addition of bony tissue at the surface of bones. Osteoblasts at the bone surface secrete bone matrix, and osteoclasts on the inner surface break down bone. The osteoblasts differentiate into osteocytes.

Where does bone resorption occur in Appositional growth?

Appositional growth can occur at the endosteum or peristeum where osteoclasts resorb old bone that lines the medullary cavity, while osteoblasts produce new bone tissue.

Where do osteoclasts break down bone?

The osteoclasts are the mediators of the continuous destruction of bone. Osteoclasts occupy small depressions on the bone's surface, called Howship lacunae; the lacunae are thought to be caused by erosion of the bone by the osteoclasts' enzymes.
