Which bone is the large bone in the upper leg?

• A. Tibia
• B. Fibula
• C. Femur
• D. Patella

Answer: (C)

The large bone in the upper leg is the femur, the thigh bone. It’s the longest and strongest bone in the body, running from the hip down to the knee to support body weight and enable movement. At the top, it forms the hip joint with the pelvis, and at the bottom it forms part of the knee joint with the tibia (and is connected to the patella, the kneecap). The other bones mentioned—tibia and fibula—are in the lower leg, while the patella sits in front of the knee. The femur’s size and position make it the correct answer.
