'''''Radius'''''
While in the human the radius and ulna are separated by an interosseus space and articulate only at their extremities, allowing for significant capability of supination and pronation, these movements are much more limited in domestic animals due to the gradual fusing of the two bones. The extreme case is exhibited by the horse.
*The Radius forms the shaft-like rod of the distal limb, which is bowed to varying degrees amont species
*The radius articulates proximally with the distal humerus, caudally with the ulna, and distally with the carpus
*Medially on the distal articular process, a '''styloid process''' projects, which is mirrored laterally by the ulna
