GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The Haversian canals are straight and long and parallel to the length of femur. The Volkmann’s canals run perpendicular to the Haversian canals, interconnecting the latter with each other and the periosteum, and extending in random directions at various angles.

Detailed explanation-3: -Perforating canals, also known as Volkmann’s canals, run at right angles to central canals. Perforating canals connect the central canal’s blood vessels with the periosteum’s blood supply.
