The name given to the proximal ulna is the Olecranon. Here's an explanation to help you understand:
1. The proximal ulna is the upper part of the ulna bone, which is one of the two bones in the forearm (the other being the radius).
2. The Olecranon is the prominent bony point at the tip of the elbow. It forms the bony prominence of the elbow joint and serves as an attachment point for muscles and ligaments involved in elbow movement.
3. When you rest your elbow on a table or lean on your elbow, you can feel the Olecranon as the hard point at the back of your elbow.
4. The Capitulum and Trochlea are parts of the humerus bone in the upper arm, while the Scaphoid is a bone in the wrist. These structures are not directly related to the proximal ulna.
Therefore, in the context of the question, the correct name for the proximal ulna is the Olecranon.
