The transverse canals that connect vessels of periosteum, medullary cavity, and central canal are known as what?

• A. Perforating canals
• B. Central canals
• C. Canaliculi
• D. Osteons

Answer: (A)

These transverse channels are perforating canals, also known as Volkmann's canals. They run perpendicular to the long axis of the bone and link the blood vessels and nerves from the periosteum with the vessels in the medullary cavity and the central canals of neighboring osteons. This connection is essential for delivering nutrients and removing wastes from osteocytes throughout compact bone. In contrast, central canals run longitudinally through the center of each osteon, canaliculi are the tiny channels that connect individual osteocytes within lacunae, and osteons are the repeating cylindrical units that make up most of compact bone.
