Osteoclasts are responsible for bone resorption and remodeling. In a growing bone, the most active area of bone growth is in the epiphyseal plate. However, osteoclasts are not as active in this region because their role is to break down old bone tissue, not to create new bone tissue. The medullary cavity is the location of bone resorption to create the marrow cavity, and so it would have the greatest osteoclast activity.
