where is an osteon located
Microscope at 400X. The outlined area is a cross section of an osteon of compact bone. In three dimensions an osteon is cylindrical in shape. In the center of each osteon is the central canal, a space that houses blood vessels and nerves that supply bone. Concentric layers of bone cells (osteocytes) and bone matrix surround the central canal. Osteocytes occupy spaces (lacunae) in the bone matrix. Osteocytes maintain the bone matrix.
