What is Femur?
[[File:Gray252.png|thumb|right|200px|The human femur]] The '''femur''' is the thigh[[bone]] in [[tetrapod]]s. It connects to the [[pelvis]] (hip) at the upper end and to the [[knee]] at the lower end. It connects with the hip by a ball-and-socket [[joint]] which allows freedom of movement. The lower end of the femur forms a [[hinge]] with the lower [[leg]] known as the [[knee]]. This has two 'articulations': with the [[patella]] (knee-cap), and with the [[tibia]] (the main lower leg bone).The femur is also the longest and strongest bone in your body. {{biology-stub}} [[Category:Bones]]
