Question

Quizplus · Accepted Answer

Perforating canals, also known as Volkmann's canals, are small channels that provide passageways for blood vessels linking the vessels of the periosteum and the marrow cavity to those of the central canals. They are important for the blood supply to bone tissue and are arranged perpendicular to the central canals. They are present in both cancellous and compact bone and are not obliterated in adult bone.
