tarsal
any of several short, angular bones that in humans make up the ankle and that-in animals that walk on their toes (e.g., dogs, cats) or on hoofs-are contained in the hock, lifted off the ground. The tarsals correspond to the carpal bones of the upper limb. In humans the tarsals, in combination with the metatarsal bones, form a longitudinal arch in the foot-a shape well adapted for carrying and transferring weight in bipedal locomotion.
