Which bone is the thick, weight-bearing bone of the lower leg that connects the knee to the ankle?

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

Answer: (D)

The thick, weight-bearing bone that runs from the knee to the ankle is the tibia, the shinbone. It’s the larger bone in the lower leg and is built to carry most of the body's weight during standing and movement. At the top, the tibia forms the knee joint with the femur, and at the bottom, it forms the main ankle joint with the talus. The fibula sits on the outside of the leg and mainly provides stability, not weight-bearing. The patella is the kneecap that protects the knee joint, and the ulna is a forearm bone, not part of the leg. So the tibia is the bone that is thick and weight-bearing, connecting the knee to the ankle.
