Lateral carpal collateral ligament

In ungulates, the lateral carpal collateral ligament attaches proximally to the lateral styloid process of the radius and divides into a superficial branch, which inserts at the proximal extremity of the lateral metacarpal bone and two deep branches, which insert at the ulnar carpal bone and the fourth carpal bone.

In carnivores, lateral collateral ligament is necessarily much weaker allowing for some adduction and abduction. It extends from the styloid process of the ulna to the ulnar carpal bone.
