Question

Quizplus · Accepted Answer

Perforating canals, also known as Volkmann's canals, transmit blood vessels and nerves from the periosteum (the outermost layer of bone) and endosteum (the innermost layer of bone) into the central canals of osteons in compact bone. They run perpendicular to the surface of the bone and are not associated with osteons in spongy bone. Perforating canals are present in adult bone and play a vital role in bone growth, repair, and metabolism.
