APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Osteocytes are the engineers and experienced builders. They make up about 90% of bone cells and are found in the bone matrix. They communicate with other cells and regulate osteoblasts’ and osteoclasts’ work to shape the bone. Thus, osteocytes are responsible for new bone growth and repair.

Detailed explanation-2: -Soon after a fracture occurs, the body acts to protect the injured area, and forms a protective blood clot and callus around the fracture. New “threads” of bone cells start to grow on both sides of the fracture line. These threads grow toward each other. The fracture closes and the callus is absorbed.

Detailed explanation-3: -Throughout life, bone is constantly being replaced in the process of bone remodeling. In this process, osteoclasts resorb bone, and osteoblasts make new bone to replace it. Bone remodeling shapes the skeleton, repairs tiny flaws in bones, and helps maintain mineral homeostasis in the blood.
