ANATOMY

Detailed explanation-1: -The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow. The perichondrium is very similar to the periosteum.

Detailed explanation-2: -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. Muscles, ligaments, and tendons may attach to the periosteum.

Detailed explanation-3: -The outer layer of the periosteum is mostly made of elastic fibrous material, such as collagen. It also contains blood vessels and nerves. The blood vessels of the periosteum contribute to the blood supply of the body’s bones. They can pass into the dense and compact layer of bone tissue below, called the bone cortex.

Detailed explanation-4: -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.
