The proximal third of this bone is broken in a Mon
The proximal third of this bone is broken in a Monteggia fracture. Like the mandible, this bone contains a triangular projection called the coronoid process. The tuberosity of this bone serves as the insertion point of the brachialis muscle, and the artery named for this bone splits into namesake anterior and posterior recurrent arteries. The nerve named for this bone can be compressed in Guyon's canal. The styloid process is on the distal end of this bone, whose proximal end terminates in a hooklike structure called the olecranon process, which articulates with the medial epicondyle of the humerus and is near the insertion point of the triceps muscle. For 10 points, name this bone on the pinky side of the forearm, which lies next to the radius.
