Tarsus

In tetrapods, the tarsus is the cluster of bones in the foot between the tibia and fibula[?] and the metatarsus[?]. The bones of the tarsus do not belong to individual toes, whereas those of the metatarsus do. The joint between the tibia and fibula and the tarsus is called the ankle[?]. One of the bones is the calcaneus[?] or heel. The corresponding part of the hand is the carpus.

Most long-footed tetrapods have an elongated metatarsus. The tarsier instead has an elongated tarsus, hence the name.

In insects, the tarsus is the series of short segments after the tibia. It is the part that functions as the foot.
