Light micrograph of a 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 an Haversian canal,a channel for the nerves and blood & lymph vessels which runs the entire length of the bone. Each of the small white areas is a lacuna,a hole in the bone which is occupied by an osteocyte or bone cell. The active form of the osteocyte is the osteoblast cell,responsible for bone formation. Each canal and it's surrounding lamellae form what's called an Haversian system. Magnification: x200 at 35mm size | |
