Ulna
One of the two forearm bones, the ulna extends from the tip of the elbow to the pinky side of the wrist.
The ulnar collateral ligament attaches to the coronoid process and the olecranon of the ulna.
Major insertions into the ulna include the triceps brachii and brachialis. Major origins include the pronator teres, pronator quadratus, and the supinator.
In the diagram, the ulna is on the right. The diagram shows the anterior view of the right elbow.
