What is the upper bone of the lower extremity called?

1. Tibia

2. Fibula

3. Femur

4. Patella

The correct answer is: Femur

The upper bone of the lower extremity is called the femur. It is the longest and strongest bone in the human body, situated in the thigh and connecting the hip to the knee. The femur plays a crucial role in supporting the weight of the body during standing, walking, and running, and it acts as a primary lever for movement in the lower limb. Its structure is designed to withstand the forces exerted on it during various activities, making it essential to lower body function. In contrast, the tibia and fibula are both located in the lower leg. The tibia is the larger and stronger of the two, where the fibula is thinner and runs parallel to it. The patella, known as the kneecap, is a small bone that sits in front of the knee joint, providing protection and facilitating knee extension. Thus, while each of these bones plays a significant role in the anatomy of the lower extremity, the femur is accurately identified as the upper bone.
