Description
Light micrograph of a thin cross-section of normal human compact bone tissue, as found in the shafts of the long bones such as the femur. The rings correspond to concentric bands of calcified material called lamellae. They are centered around the Haversian canals (green/gold regions), channels for the nerves and blood & lymph vessels which run the entire length of the bone. Each of the dark spider-like areas are lacunae, a hole in the bone occupied by an osteocyte, a bone cell. The active form of the osteocyte is the osteoblast cell, responsible for bone formation. Each canal and its surrounding lamellae form an Haversian system. Magnification: x50 at 35mm size.
