GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The periosteum is the membrane covering the outside of the diaphysis (and epiphyses where articular cartilage is absent). It contains osteoblasts (bone‐forming cells), osteoclasts (bone‐destroying cells), nerve fibers, and blood and lymphatic vessels. Ligaments and tendons attach to the periosteum.

Detailed explanation-3: -periosteum, dense fibrous membrane covering the surfaces of bones, consisting of an outer fibrous layer and an inner cellular layer (cambium). The outer layer is composed mostly of collagen and contains nerve fibres that cause pain when the tissue is damaged.

Detailed explanation-4: -The outer walls of the diaphysis (cortex, cortical bone) are composed of dense and hard compact bone, a form of osseous tissue.
