Which is the smaller of the two lower leg bones?

Explanation:
In the lower leg, size and weight-bearing role distinguish the two bones. The tibia is the larger bone that bears most of the body’s weight and forms the main knee and ankle joints, while the fibula is the smaller, slender bone on the outer side that mainly provides muscle attachment and helps stabilize the ankle. The femur is the thigh bone, not part of the lower leg, and the calcaneus is the heel bone in the foot. Therefore, the smaller of the two lower leg bones is the fibula.
