Legs are made up of a complex system of bones, muscles, skin, veins and arteries which work hard to support you through your busy day. Please move the mouse over the red areas to learn more.
The largest, longest and strongest bone in the human body is the femur, which is in the upper leg. Both the front and the back of the upper leg are well muscled, and supply much of the strength and power for the leg.
The knee forms the joint between the femur and the lower bone of the leg, the tibia. The knee is protected and stabilised by the patella (also known as the kneecap), a flat, triangular bone. Ligaments and tissue help to stabilise the knee against excessive side-to-side movement, and cartilage acts to cushion the junction of the femur and the tibia.
The tibia is the second longest bone in the body after the femur. It extends the length of the lower leg, from the knee to the ankle. The back of the lower leg is also well muscled and these muscles assist with leg and foot motion.
