DescriptionUnreviewed
The femur (pl. femurs or femora), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates.
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 (shinbone) and patella (kneecap), forming the knee joint.
By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest.
