Explanation:
Detailed explanation-1: -The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
Detailed explanation-2: -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.
Detailed explanation-3: -Haversian canals (sometimes canals of Havers) are a series of microscopic tubes in the outermost region of bone called cortical bone.
