The calcis is the:

• A. Calcaneus
• B. Calcium in a joint
• C. Arthritis of the hand
• D. Bone in forearm

Answer: (A)

Calcis refers to the heel area, and in anatomy the heel bone is the calcaneus. The calcaneus is the largest bone of the foot’s tarsal bones, forming the heel and serving as the attachment point for the Achilles tendon. It sits under the talus and supports weight during standing and walking. That’s why the correct choice is calcaneus. The other options describe either a substance (calcium in a joint), a disease (arthritis of the hand), or a different bone location (bone in the forearm), none of which identify the heel bone.
