The periosteum helps bone growth. The outer periosteum layer contributes to the blood supply of your bones and the surrounding muscles. It also contains the network of nerve fibers that transmit messages throughout your body. The inner layer helps to protect your bones and stimulates repair after an injury or fracture.
