Through the interaction of preexisting and newly formed osteoclasts with osteoblasts, resorption is initiated in discrete areas. This phase, which lasts 2–

Agents that regulate bone formation may act either by increasing or decreasing the number of cells available to form new bone or by modifying the

The osteoblasts are very possibly, together with the osteocytes, responsible for selecting the area that is to be removed, while the osteoclasts are the cells that actually carry out th
