The calcis is the heel bone.

• A. The heel bone
• B. The elbow
• C. A calcium deposit in the bone
• D. The wrist

Answer: (A)

Calcis, in anatomical terms, refers to the heel bone, scientifically known as the calcaneus. This large bone forms the heel at the back of the foot and is essential for weight bearing and push-off during walking. It articulates with the talus above to form the subtalar joint and serves as the attachment point for the Achilles tendon. The elbow and wrist are different parts of the body, and a calcium deposit in bone describes calcification, not the bone itself. So the heel bone is indeed the calcis.
