Chapter 6 - Periosteum and Endosteum

Functions of periosteum

1. Isolates bone from surrounding tissue 2 Route for blood vessels and nerves for the bone 3. Helps in growth and repair

Two membrane layers of periosteum

1. Outer fibrous layer 2. Inner osteogenic layer (composed of bone cells)

Endosteum

Delicate membrane covers internal surfaces of bone Has osteoprogenitor cells and osteoclasts

Periosteum

Double layer of membrane that covers bones Becomes continuous with other connective tissue (joint capsule, tendons, ligaments)

Functions of endosteum

Functions in growth, repair, and remodeling

Sharpey's fibers

anchor periosteum to bone
