Compact bone consists of outer and inner sheets of lamellar bone (not seen here) and Haversian systems, shown here, that run parallel to the long axis of bones. The concentric rings of lamellar bone that surround a Haversian canal can be viewed in higher detail in slide number 7 and 8. Osteocytes can be seen in the concentric rings of the bone matrix. Haversian canals contain nerves, blood vessels, and lymphatic vessels. Connecting adjacent Haversian canals at right angles are Volkmann's canals.
