Which bone is known as the heel bone?

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

Answer: (C)

Heel bone refers to the calcaneus, the largest bone in the foot’s tarsal group, located at the back of the foot. It forms the prominent heel that bears most of the body's weight when standing and during movement. The calcaneus has a strong area called the calcaneal tuberosity where the Achilles tendon attaches, linking the heel to the calf muscles. It sits beneath the talus, with the ankle joint formed between them; the tibia and fibula are the leg bones that meet the foot at the ankle but are not the heel itself. The talus is the ankle bone that sits above the calcaneus and helps form the ankle joint, not the heel. So, the heel bone is the calcaneus.
