Which bone forms the thigh and is the longest?

Which bone forms the thigh and is the longest?

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

Answer: (C)

The bone that forms the thigh and is the longest in the body is the femur. It runs from the hip down to the knee and is built to bear a lot of weight and resist big forces during activities like walking, running, and jumping. The other bones listed are located elsewhere: the fibula is a thinner bone on the outer side of the lower leg, not in the thigh; the tibia is the main weight-bearing bone of the lower leg between the knee and ankle; and the patella is the kneecap in front of the knee joint. So, the femur fits both parts of the question: it forms the thigh and it is the longest bone.
