This video tutorial covers the anatomy of the ulna and radius, two bones in the forearm. It explains their positions in anatomical terms, with the radius being lateral and the ulna medial. The video details the key features of the ulna, such as the olecranon process and trochlear notch, and the radius, including the radial tuberosity and styloid process. It also discusses the interosseous membrane, a fibrous structure connecting the two bones, providing stability. The tutorial aims to enhance understanding of these bones' roles in the arm's structure and function.
