Study Notes
Osteon Structure
- Osteons (Haversian systems) are the basic units of compact bone.
- They consist of concentric rings of bone matrix called lamellae.
- A central canal (Haversian canal) runs through the center of each osteon, containing blood vessels and nerves.
Components of an Osteon
- Lamellae are thin layers of bone matrix that arrange around the central canal.
- Lacunae are small spaces within the bone matrix that house osteocytes.
- Canaliculi are tiny channels that connect lacunae. They allow for nutrient and waste transport between osteocytes.
- Osteocytes are mature bone cells that maintain bone tissue and communicate via canaliculi.
