Which bone is the outer, thinner bone of the leg between the knee and ankle?

• A. Fibula
• B. Tibia
• C. Talus
• D. Tarsals

Answer: (A)

Two long bones run from the knee to the ankle: the tibia and the fibula. The fibula is the thinner, outer bone, located on the lateral (outside) side of the leg, and its distal end forms the lateral malleolus for ankle stability. While the tibia bears most of the body's weight, the fibula mainly provides muscle attachment and helps stabilize the ankle. The talus and other tarsal bones belong to the foot, not the leg, so they aren’t the outer, thinner leg bone between knee and ankle.
