Which of the following is a tarsal bone?

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

Answer: (A)

Tarsal bones are the seven ankle bones that form the hindfoot and midfoot. The calcaneus, or heel bone, is one of these bones and is the largest, sitting at the back of the foot to form the heel and to anchor the Achilles tendon. It also articulates with the talus to create the subtalar joint, helping with weight transfer when you stand and move. The other bones listed aren’t part of the tarsal group: the tibia and fibula are in the lower leg, and the metatarsals are the long bones in the midfoot leading to the toes. So the calcaneus is the tarsal bone.
