What is the name of the vascular channel that runs perpendicular to the central canals in compact bone?

• A. Haversian canal
• B. Volkmann's canal
• C. Central canal
• D. Interstitial canal

Answer: (B)

Volkmann's canals are the vascular channels that run perpendicular to the central canals in compact bone. They perforate the bone and connect neighboring Haversian (central) canals, carrying blood vessels and nerves from the periosteum and marrow cavity into the bone. This perpendicular orientation links the osteons together and distributes nutrients across the dense lamellar structure. The central canal inside each osteon is the longitudinal channel (also called the Haversian canal), so that is not perpendicular. The term “interstitial canal” isn’t a standard feature of bone vasculature, whereas canaliculi are microscopic channels that connect lacunae but aren’t major vascular conduits like Volkmann’s canals.
