Endosteum plays an important role in bone repair, bone remodelling and appositional bone growth.
Explanation:
Endosteum consists of a soft and thin connective tissue that lines the cavity of femur and humerus. Some of the major functions of endosteum are as follows:
Bone remodelling: Endosteum can stimulate the bone resorption that leads to the formation of new bone from the outside.
Bone repair: Hematoma, at the time of bone injury causes the division of endosteal cells and helps in bone repair.
Appositional bone growth: Endosteum that line the osteoblast cell can secrete bone matrix and increases the bone diameter.
