Study Notes
Elbow Joint Movement
- The radius moves around the fixed radius in the elbow joint, while the ulna remains relatively stationary.
- The movement described is rotation and occurs at the proximal radioulnar joint, where the radius rotates around the ulna.
- The humerus is the fixed bone in the elbow joint, acting as the pivot point for radius movement.
- The scapula does not directly participate in the motion of the elbow joint.
- The radius plays the primary role in rotation at the elbow joint, allowing for pronation and supination of the forearm.
