Blood and nerve supply of bone

Blood and nerve supply of bone is made possible by arteries, veins, nerves and Lymph vessels.

Arteries supply of bones

The bones are highly vascular. The bone is supplied with blood externally on the surface and internally on the lining of the medullary cavity.

The surface arteries ramify over the periosteum and large blood vessels gain entrance through the nutrient foramen and branches widely along the course and on the endosteal lining  of the bone. Thus there is a network of blood vessels over the entire bone.

Veins supply of bones

Veins are accompany the arteries and mostly recurrent in nature.

Nerves supply of bones

Nerve accompany the blood vessels. The periosteal branches are sensory types of nerve fibers.

Lymph vessels supply of bones

Lymph vessels run in company with blood vessels of the marrow, forming a network under the periosteum.
