Radius and Ulna - Bone Landmarks, Joints and Functions | Anatomy

Explore the detailed anatomy of the forearm bones through this comprehensive 12-minute educational video that systematically examines the radius and ulna bones, their anatomical landmarks, joint relationships, and functional movements. Begin with an in-depth analysis of the radius bone, starting from the proximal end including the head, articular facet, neck, and radial tuberosity, then progress through the shaft's borders and surfaces, and conclude with the distal features like the styloid process and carpal articular surface. Continue with a thorough examination of the ulna bone, covering the prominent olecranon, trochlear notch, coronoid process, and other proximal landmarks, followed by the shaft anatomy and distal structures including the ulnar head and styloid process. Watch detailed movement animations demonstrating how the radius and ulna work together during forearm rotation, and learn about the critical joints connecting these bones including the proximal and distal radioulnar joints, radiocarpal joint, and elbow joint components. Master the anatomical terminology for each bone landmark, understand the attachment sites for muscles and ligaments, and grasp the functional relationships between these structures that enable complex forearm and wrist movements essential for daily activities.
