radius (in anatomy) The smaller of the two bones in the lower section of the forelimb of a tetrapod vertebrate (compare ulna). The radius articulates with some carpal bones and the ulna at the wrist and with the humerus at the elbow. This sophisticated articulation of the radius enables humans (and some other animals) to twist the forearm (see pronation; supination).
