The large bone of the leg, connected to the knee joint and ankle joint?

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

Answer: (B)

Understanding which bone links the knee to the ankle and bears most of the body's weight helps identify the correct answer. The tibia, or shin bone, is the large lower-leg bone that spans from the knee to the ankle. Proximally, it forms the knee joint with the femur, and distally it participates in the ankle joint by articulating with the talus (alongside the fibula). The fibula runs parallel but is thinner and does not bear the main load. The patella sits in front of the knee, not at the ankle, and the femur is the thigh bone that connects to the knee above but does not form the ankle joint. So the bone described is the tibia.
