The Intercarpal Joints between the bones of the carpus are all gliding joints, and they have numerous ligaments between the adjacent bones; in addition to this, the carpus is surrounded by a complete capsule.

The synovial membrane lines the joint, and may have a separate division for the articulation between the cuneiform and pisiform bones.

These both ventrally and dorsally are arranged in two sets, superficial and deep; on the flexor (ventral) surface, the superficial group comes from the inner condyle of the humerus, and the deep ones from the ventral surfaces of the ulna and radius; on the extensor (dorsal) surface the superficial group comes from the outer condyle of the humerus, and the deep ones from the dorsal surfaces of the ulna and radius. Thus both superficial groups act on the elbow-joint.
