The groove at the heelbone is called which feature?

Explanation:
The groove on the heelbone is called the calcaneal sulcus. A sulcus is the anatomical term for a groove or furrow in bone, and the heelbone (calcaneus) has this groove on its superior surface that helps define the articulation with the talus, contributing to the subtalar joint. Other terms describe different bone features: a canal implies a tunnel, a fossa is a shallow depression, and a groove at the talonavicular joint would be a different location. So the groove inherent to the heelbone is the calcaneal sulcus.
