MICROANATOMY

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: -Each osteon consists of lamellae, which are layers of compact matrix that surround a central canal called the Haversian canal. The Haversian canal (osteonic canal) contains the bone’s blood vessels and nerve fibers (Figure 1).

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.

Detailed explanation-4: -Compact Bone The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix.

Detailed explanation-5: -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). A Haversian canal generally contains one or two capillaries and nerve fibers.
