GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann’s canals, to extend to the periosteum and endosteum.

Detailed explanation-3: -A central Haversian canal penetrates the osteon and serves as a passage for blood cells, lymph vessels, and nerves.
