GENERAL HISTOLOGY

Detailed explanation-1: -The periosteum is composed of two layers: The outer firm and a fibrous layer made up of collagen and reticular fibers and an inner proliferative cambial layer. The periosteum is identifiable on the outer surface of the bone; both layers of the periosteum can be differentiated.

Detailed explanation-2: -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-3: -The periosteum is a dense, fibrous connective tissue sheath that covers the bones. The outer layer, made up of collagen fibers oriented parallel to the bone, contains arteries, veins, lymphatics, and sensory nerves. The inner layer contains osteoblasts (i.e., cells that generate new bone formation).

Detailed explanation-4: -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.
