Question

The bones of mammals contain haversian canals which are interconnected by transverse canals known as:

• A. Canaliculi
• B. Volkmann's canal
• C. Lacunae
• D. Bidder's canal

Answer 1

The correct option is B Volkmann's canal

The compact bone in mammals is made up of several osteons or haversian systems. Each osteon has a central canal known as haversian canal. The haversian canals are sorrounded by concentric rings of matrix. The matrix has spaces called lacunae in which osteocytes are present. Canaliculi are fine canals between the lacunae. Volkmann's canal interconnects the haversian canals.


Bidder's canal is found in the kidney of frog.
