The olecranon process is which option?

• A. Capitulum
• B. Olecranon process
• C. Radial head
• D. Medial epicondyle

Answer: (B)

The olecranon process is the large, posterior bump at the proximal end of the ulna—the forearm bone. It forms the point of the elbow and serves as the triceps muscle attachment. On imaging, you’d identify it as the prominent posterior projection that sits against the olecranon fossa of the distal humerus when the elbow is extended. The other structures mentioned are located elsewhere: the capitulum is on the distal humerus and articulates with the radial head; the radial head is part of the radius itself; the medial epicondyle is a projection on the inner side of the distal humerus.
