MICROANATOMY

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: -PERIOSTEUM (d)-dark blue Periosteum is a fibrous, vascular, sensitive life support covering for bone. It provides nutrient-rich blood for bone cells and is a source of bone-developing cells during growth or after a fracture.

Detailed explanation-3: -The osteoblast, the bone cell responsible for forming new bone, is found in the growing portions of bone, including the periosteum and endosteum. Osteoblasts, which do not divide, synthesize and secrete the collagen matrix and calcium salts.

Detailed explanation-4: -The periosteum is a membranous tissue that covers the surfaces of bones. It is an intricate structure composed of an outer fibrous layer that gives structural integrity and an inner cambium layer that possesses osteogenic potential.
