In compact bone histology, the Haversian system (osteon) consists of concentric lamellae around a central canal. The transverse/oblique canals connecting adjacent Haversian canals to the periosteum and to each other are called:
- A Sharpey's fibres
- B Canaliculi
- C Howship's lacunae
- D Volkmann's canals ✓
Explanation
Volkmann's canals (perforating canals) run perpendicular or obliquely to the long axis of the bone, connecting the periosteal surface to the Haversian canals and connecting adjacent Haversian canals to each other and to the endosteum. They carry blood vessels and nerves. Canaliculi are the tiny interconnecting channels between osteocyte lacunae within a single Haversian system. Sharpey's fibres are collagen fibres anchoring tendons/ligaments into bone. Howship's lacunae are the resorption pits on bone surfaces created by osteoclasts.
