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

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

Answer: (A)

The outer and thinner bone of the leg between the knee and ankle is the fibula. It lies on the lateral (outer) side of the leg and runs parallel to the larger tibia, which sits on the inside. The fibula doesn’t bear much weight—the tibia does most of the heavy lifting. The talus and other tarsal bones belong to the foot and form the ankle with the tibia and fibula, with the distal end of the fibula creating the lateral malleolus to help stabilize the ankle.
