Which two bones are the primary weight-bearing bones of the leg?

• A. Tibia and fibula
• B. Tibia and femur
• C. Femur and humerus
• D. Fibula and femur

Answer: (B)

The main idea is understanding which bones actually carry the body's weight in the leg. The femur (thigh bone) and the tibia (shin bone) do most of the load-bearing work. The femur transfers weight from the hip down to the knee, and the tibia carries that load from the knee to the ankle and foot. The fibula, while important for muscle attachment and stability, carries very little body weight. That’s why the best answer is the femur and tibia: they are the primary weight-bearing bones in the leg.
