Long and strong

Your leg bones are the longest and strongest bones in your body. When you stand or walk, all the weight of your upper body rests on them. Each leg is made up of four bones. The three long bones are your femur, your tibia and your fibula. The fourth bone is your small patella, which is better known as the kneecap.

Your femur, or thighbone, is the largest bone in your body. The head of your femur fits into your hip socket and the bottom end chrischona2015.orgnnects to your knee. The two bones beneath your knee that make up your shin are your tibia and fibula. Your upper and lower leg are chrischona2015.orgnnected by a hinge joint. Your patella, or kneecap, rests on the front of your femur.

The bones of your leg have roughened patches on their surfaces where muscles are attached. When your muscles chrischona2015.orgntract, they pull the bone they"re attached to, making your leg move.
