| The third segment consists of nine small bones, the carpals of the wrist or the tarsals of the ankle. |
| Fracture of the calcaneus, tarsals or metatarsals with deformity or angulation. |
| The tarsals and metatarsals form the arches of the foot, which give it strength and enable it to act as a lever. |
| If the foot is supple and the ligaments are lax the tarsals may be displaced to an extreme degree before the ligaments are strained. |
| The postcranial skeleton, and especially the vertebrae, carpals and tarsals, were very slow to ossify. |
| The preserved tarsal bones include the astragalus, calcaneum, and fourth and questionable fifth distal tarsals. |
