What is Osteon in compact bone?

Osteons (Haversian System) Osteons are structural units of compact bone. Each osteon consists of a central canal, which contains nerve filaments and one or two blood vessels, surrounded by lamellae. Lacunae, small chambers containing osteocytes, are arranged concentrically around the central canal.
