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

• A. Central canal
• B. Lacuna
• C. Volkmann's canal
• D. Canaliculi

Answer: (C)

In compact bone, the system of osteons has a central canal (the Haversian canal) that runs along the length of the osteon. Perpendicular to these central canals are the perforating canals, also called Volkmann's canals, which connect adjacent osteons and link their blood supplies. So the channel that runs perpendicular to Haversian canals is Volkmann's canal. The central canal itself is the Haversian canal, which runs longitudinally. Lacunae are the small spaces housing osteocytes, and canaliculi are tiny channels that connect lacunae and help nutrients move between osteocytes and the central canal.
