Study Notes
Osteon Structure and Functions
- Haversian Canal: Central channel in an osteon that allows passage of blood vessels, nerves, and provides essential nutrients to bone tissue.
- Lamellae: Concentric layers of compact bone tissue encircling the Haversian canal, contributing to the structural integrity and strength of bones.
- Interstitial Lamellae: Remnants of old or destroyed osteons found in the spaces between active osteons; these fragments contribute to the mechanical stability of long bones.
- Lacunae and Osteocytes: Tiny cavities located between lamellae that house osteocytes, facilitating communication and nutrient exchange among bone cells.
- Canaliculi: Microscopic channels that connect lacunae to each other and to the Haversian canal; they serve as pathways for the transport of nutrients and waste products between osteocytes and the blood supply.
