Which bone is known as the heel bone?

• A. Talus
• B. Navicular
• C. Cuboid
• D. Calcaneus

Answer: (D)

The heel bone is the calcaneus. It’s the large bone at the back of the foot that forms the prominent heel and bears much of the body's weight during standing and walking. The calcaneus provides the attachment for the Achilles tendon at its back edge, and it sits beneath the talus to form the ankle and subtalar joints, which allow movement between the foot and leg. The other bones—such as the talus, which sits on top to form the ankle joint, and the navicular and cuboid, which are part of the midfoot—do not constitute the heel itself. So, the heel bone is the calcaneus.
