Which bone is the calfbone?

• A. Tibia
• B. Humerus
• C. Fibula
• D. Radius

Answer: (C)

Calf bone terminology points to the fibula. The leg has two parallel bones: the larger, weight-bearing tibia (the shinbone) and the thinner fibula on the lateral side. The fibula is the bone most commonly referred to as the calf bone, even though it isn’t the main weight-bearing bone—that distinction belongs to the tibia. The arm bones listed (humerus and radius) are in the upper limb, so they don’t fit.
