(c) : Pivot joint is present between atlas and the axis in humans. In this joint articular end of one bone is fixed while the other can rotate over it. In angular joint, an oval condyle of one bone fits into an elliptical concavity of the other, e.g., wrist and metacarpophalangeal joints. Hinge joint allows movements in one plane only, e.g., knee joint. In saddle joint, small projection of one bone fits into a saddle like depression of another bone.
