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

• A. Ulna
• B. Vertebra
• C. Trapezius
• D. Tibia

Answer: (D)

In the lower leg, the main weight-bearing and larger bone is the tibia. It’s the shinbone and carries most of the body’s weight from the knee down to the ankle during standing and movement. The tibia is thick and strong, forming the primary load-transmitting link between the femur above and the foot below, with the medial malleolus at the ankle end contributing to stability.

The other bone in the lower leg, the fibula, is thinner and sits on the outside of the leg. It doesn’t bear significant weight but provides muscle attachment and helps stabilize the ankle.

So when asked which bone is both weight-bearing and the larger one in the lower leg, the tibia is the correct choice. The other names belong to different parts of the body.
