MICROANATOMY

Detailed explanation-1: -Each central canal runs parallel to the long axis of the bone. It’s where blood vessels, lymph vessels, and nerves are located. It also contains a small amount of connective tissue. Perforating canals, also known as Volkmann’s canals, run at right angles to central canals.

Detailed explanation-2: -Compact Bone Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels.

Detailed explanation-3: -Volkmann’s canals, also known as perforating holes or channels, are anatomic arrangements in cortical bones. Volkmann’s canals are inside osteons. They interconnect the haversian canals with each other and the periosteum.

Detailed explanation-4: -Haversian canals are a series of tubes around narrow channels formed by lamellae. The Haversian canals surround blood vessels and nerve fibers throughout the bone and communicate with osteocytes. The canals and the surrounding lamellae are called a Haversian system (or an osteon).
