The rounded posterior portion of the foot under and behind the ankle.
A similar anatomical part, such as the rounded base of the palm.
[last sense fr heel, ''arm a fighting cock with a gaff or spur,'' found by 1755]
in anatomy, back part of the human foot, below the ankle and behind the arch, and the corresponding part of the foot in other mammals that walk with their heels touching the ground, such as the raccoon and the bear; it corresponds to the point of the hock of hoofed mammals and those that walk on their toes (e.g., horse, dog, cat). The contained tarsal bone, the calcaneus, appears first among the crocodilian reptiles; it was lost in birds by fusion with other tarsals and metatarsals but retained in mammals.
