Detailed explanation-2: -The periosteum covers all surfaces of the bone except for those capped with cartilage, as in the joints, and sites for attachment of ligaments and tendons.

Detailed explanation-3: -The tough, thin outer membrane covering the bones is called the periosteum. Beneath the hard outer shell of the periosteum are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone.

Detailed explanation-4: -It’s made of thick collagen fibers. Most of the periosteum’s blood vessels and nerves are in the outer layer. The inner layer (sometimes called the cambium layer) contains the osteoprogenitor cells and the osteoblasts they create when your bone is growing or needs to heal.
