Question

Quizplus · Accepted Answer

Perforating canals, also known as canals of Volkmann, are larger canals that run at right angles to the central canals of osteons. They penetrate the periosteum and connect the blood and nerve supply of the periosteum to those of the central canals and medullary cavity. Perforating canals are responsible for transmitting blood vessels and nerves from the periosteum into the bone and also from the medullary cavity into the bone.
