Leg anatomy. Computer artwork of an oblique side view looking down a human leg,showing muscles and tendons (brown and white),bones and ligaments (white),arteries and veins (red and blue),nerves (yellow),and lymph vessels (green). The upper leg (thigh) articulates with the lower leg at the knee,and the lower leg articulates with the foot at the ankle. The main bones are the femur,tibia and fibula. The arteries and veins arise from the groin,and the nerves arise from the spinal cord. The dorsal surface of the foot includes extensor muscle tendons extending to each toe,allowing them to be straightened. Ligaments are also shown |
