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

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

Answer: (C)

The main idea here is identifying which bone in the lower leg actually carries most of the body's weight and is the larger of the two leg bones. The tibia fits that role: it is the larger, weight-bearing bone of the lower leg and transmits forces from the knee down to the ankle. The fibula is thinner and mainly serves for muscle attachment and lateral stability, not for bearing most of the body's weight. The patella is a kneecap that protects the knee and improves leverage for leg extension, not a weight-bearing bone of the lower leg. The femur is the thigh bone, located above the knee, and while very weight-bearing, it is not part of the lower leg. Therefore, the tibia is the correct bone.
