What is the end of the radius at the elbow called?

Explanation:
The end of the radius at the elbow is called the radial head. This rounded proximal end of the radius sits near the elbow and articulates with the capitulum of the humerus, forming part of the elbow joint and allowing forearm rotation. The capitulum is a part of the humerus, not the radius, so it isn’t the end of the radius. The radial tubercle is a bump on the shaft of the radius for muscle attachment, not at the elbow. The ulnar head is at the distal end of the ulna near the wrist, far from the elbow part of the radius. So the correct term for the radius’s end at the elbow is the radial head.
