Normal Bone

Normal Bone •A high power (40x) image of normal bone. •The larger "holes" are the Haversian Canals. •These are normally occupied by the blood vessels that supply blood with nutrients. •The small holes are the lacunae that house the osteocytes. •In some of the lacunae, you can see the dark dots that represent the stained nuclei of the osteocytes. •The green arrow points to the cement lines that lie between successive depositions of bone formation by the osteocytes. •Notice that the cement lines are smooth and form graceful curves that run through the substance of the bone in this image.
