Which bone is the weight-bearing and larger bone of the lower leg?

• A. Fibula
• B. Ulna
• C. Scaphoid Bone
• D. Tibia

Answer: (D)

Weight-bearing in the lower leg is handled by the larger, sturdy bone that runs from knee to ankle. That bone is the tibia, which supports most of the body’s weight and forms the main articulation with the knee cap and the ankle. The fibula is thinner and mainly serves for muscle attachment and lateral stability at the ankle, not for bearing weight. The ulna is an arm bone, not part of the leg, and the scaphoid is a small carpal bone in the wrist. So the weight-bearing and larger bone of the lower leg is the tibia.
