What is "femur"?

The femur is the largest bone in the human body. It is located in the thigh region and extends from the hip joint to the knee joint. The femur is a weight-bearing bone that provides structural support and stability to the lower body. It plays a critical role in walking, running, and various lower limb movements. The femur's unique shape and composition allow for the attachment of numerous muscles involved in hip and knee movements. As a crucial component of the skeletal system, the femur not only supports the body's weight but also protects the underlying structures, such as blood vessels and nerves, while facilitating efficient and coordinated leg movements.
