Haversian System

This magnified view of a Haversian system shows a prominent Haversian canal surrounded by concentric rings of lamellar bone in which osteocytes are embedded in their lacunae. Note the numerous canaliculi around the osteocytes. These are small canals in the bone matrix through which the osteocytes send thin cytoplasmic extensions. They allow the osteocytes to access the blood supply of the bone and to communicate with one another.
