where is your femur located in your body
Femur
The femur ( / ˈfiːmər / , pl . femurs or femora / ˈfɛmərə , ˈfɛmrə / ) or thigh bone , is the most proximal ( closest to the hip joint ) bone of the leg in tetrapod vertebrates capable of walking or jumping , such as most land mammals , birds , many reptiles such as lizards , and amphibians such as frogs . In vertebrates with four legs such as dogs and horses , the femur is found only in the hindlimbs . The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint , while the distal part of the femur articulates with the tibia and kneecap forming the knee joint . By most measures the femur is the strongest bone in the body . The femur is also the longest bone in the human body .
