Question

Quizplus · Accepted Answer

The bone with a trochlear notch and an olecranon process is the ulna. The trochlear notch is part of the ulna's articulation with the humerus and the olecranon process forms the bony prominence of the elbow. The humerus does not have an olecranon process and the radius does not have a trochlear notch. The scapula is a bone of the shoulder and does not have an olecranon process or trochlear notch. The carpal bones are in the wrist and do not have either structure.
