The 'Haversian canal' in compact bone contains: MCQ with Answer and Explanation

The Haversian canal (central canal) is the core of the osteon (Haversian system) in compact bone. It runs parallel to the long axis of the bone and contains the blood vessels (arterioles, venules, capillaries), nerve fibers, and lymphatic vessels that supply the bone tissue. The concentric lamellae surround this canal. Osteocytes are housed in lacunae between the lamellae, and red bone marrow is found in the medullary cavity of long bones or the spaces of spongy bone.
