where is the tibia and femur
The tibia is located in the lower leg medial to the fibula, distal to the femur and proximal to the talus of the foot. It is widest at its proximal end near the femur, where it forms the distal end of the knee joint before tapering along its length to a much narrower bone at the ankle joint....
The femur, or thigh bone, is the longest, heaviest, and strongest bone in the body. It supports the entire body's weight during most activities; the muscles of the hip and thigh are exceptionally strong as they must move the leg. Structurally, the femur is classified as a long bone.
