Detailed explanation-1: -The tough, thin outer membrane covering the bones is called the periosteum. Under the hard outer shell of the periosteum are tunnels and canals. Through these, blood and lymphatic vessels carry nourishment for the bone. Muscles, ligaments, and tendons may attach to the periosteum.

Detailed explanation-2: -A living bone’s surface is covered with a tough, tight-fitting membrane called the periosteum (pur ee AHS tee um). Small blood vessels in the periosteum carry nutrients into the bone. Cells involved in the growth and repair of bone also are found in the periosteum.

Detailed explanation-3: -The periosteum is a complex structure composed of an outer fibrous layer that lends structural integrity and an inner cambium layer that possesses osteogenic potential. During growth and development it contributes to bone elongation and modeling, and when the bone is injured, participates in its recovery.

Detailed explanation-4: -Almost all your bones are covered in a periosteum. It covers every part of your bones except places capped in cartilage and the spots where ligaments and tendons attach.

Detailed explanation-5: -The periosteum is a fibrous sheath that covers bones. It contains the blood vessels and nerves that provide nourishment and sensation to the bone. The periosteum tends to be thicker in younger people. The thickness decreases when the bones are mature. The periosteum also allows bone to grow and remodel after fracture.
