Which bone is the thighbone?

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

Answer: (D)

Identifying the bone by region: the thighbone is the femur. It runs from the hip to the knee and is the longest, strongest bone in the body, built to bear most of the body's weight. The femoral head fits into the hip socket, with a neck and notable muscle-attachment areas like the greater trochanter. Distally, it forms part of the knee with the tibia. The other bones listed aren’t in the thigh: the fibula is the thinner bone on the outer side of the lower leg; the tibia is the shinbone that bears most weight in the lower leg; and the patella is the kneecap that sits in front of the knee joint.
