According to the BBC, the leg bones are collectively the strongest bones in the human body because they support the entirety of the human body's substantial weight. The human leg consists of three long bones: the femur, the tibia and the fibula. Legs also have one small bone, the patella.
The femur is the largest of these bones, and the largest bone in the human body. It forms the thigh, while the tibia and fibula form the shin together. Finally, the patella is the protective bone that forms the kneecap. These bones are all connected by hinge joints, allowing the human leg to bend at the knee, hip and ankle, notes the BBC.
