GENERAL HISTOLOGY

Detailed explanation-1: -A Haversian canal generally contains one or two capillaries and nerve fibers.

Detailed explanation-2: -The osteonic canals contain blood vessels that are parallel to the long axis of the bone. These blood vessels interconnect, by way of perforating canals, with vessels on the surface of the bone.

Detailed explanation-3: -The central canal of an osteon contains the nerves and blood vessels that supply that area of bone. The central canal, also called the haversian canal, is an open space that runs through the middle of the osteon. Bone is living tissue, and it must have blood flow and nerves connected to it.
