Bones of the foot, side view. In this figure the bones of the tarsus extend from the heel to <em>a</em>; the metatarsal bones are at <em>b</em>; and the bones of the toes are at <em>c</em>. In every movement of the foot there is some little motion between all these bones, and it is this that gives ease and grace to its motions.
