Detailed explanation-1: -The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced.
Detailed explanation-2: -This process of skeletal change is known as bone remodeling, which both protects the structural integrity of the skeletal system and metabolically contributes to the body’s balance of calcium and phosphorus. Remodeling entails the resorption of old or damaged bone, followed by the deposition of new bone material.
Detailed explanation-3: -Osteoblasts secrete the osteoid into this membrane to form a spongelike network of bony processes called trabeculae. The new bone formation radiates outward from ossification centres in the membrane. This process is called intermembranous ossification.
