"thighbone" 的定义和意义

What is "thighbone"?

The thighbone is the longest and strongest bone in the human body. The femur connects the hip joint to the knee joint, providing structural support and stability to the leg. It plays a crucial role in weight-bearing, locomotion, and various movements such as walking, running, and jumping. The femur's shape and structure are designed to withstand considerable forces and transmit them from the hip to the lower leg. Additionally, the femur serves as an attachment site for several muscles involved in leg movement and contributes to the overall alignment and function of the lower limb.
