Upper Limb Anatomy and Functions

This video tutorial explores the anatomical landmarks of the ulna and radius, the two bones of the forearm. The ulna is identified by its U-shaped proximal end, featuring the olecranon, trochlear notch, and coronoid process. The radius is noted for its circular head and radial tuberosity. Both bones have a styloid process at their distal ends. The video also clarifies common confusions between similar anatomical terms.
