Final answer:
The styloid process found on the lateral side of the antebrachium is on the radius, not the ulna, humerus, or femur.
Step-by-step explanation:
The styloid process on the lateral side of the antebrachium, which is part of the forearm, is found on the radius. The radius is located on the lateral side, parallel to the ulna, and features the styloid process of the radius at its distal end. This pointed projection provides attachment for ligaments that support the lateral side of the wrist joint. The ulna, on the other hand, contains the styloid process on its medial end, which is a short bony projection on the posterior side of the ulnar head, serving as an attachment point for the connective tissue between the distal ends of the ulna and radius.
