Instructor solution
The periosteum is a dense, fibrous membrane covering the outer surface of bones, except at joint surfaces. It plays a vital role in bone health and repair by serving as an attachment point for tendons and ligaments, providing a blood supply to the bone, and housing osteoprogenitor cells that can differentiate into osteoblasts. These cells are crucial for bone growth and repair, as they contribute to the formation of new bone tissue during growth and healing processes. The periosteum also contains nerve fibers, making it sensitive to pain and injury.

The periosteum helps bones grow and stay healthy. Its outer layer provides blood to the bones and nearby muscles and contains nerves that send signals through the body. The inner layer protects the bones and supports healing after an injury or break.
