The olecranon process is part of which bone?

The olecranon process is a prominent bony structure that is located at the proximal end of the ulna, one of the two long bones in the forearm. This specific part of the ulna acts as a lever for the muscles that extend the elbow, which is crucial for arm movement. The olecranon serves as the point of the elbow that can be felt on the posterior side, making it significant in both anatomy and practical applications in medical or health-related fields.

Understanding the role of the olecranon process also highlights its importance in activities that require extension and flexion of the arm, making it a critical area for musculoskeletal health. The shape and location of this bony prominence facilitate its functional relationships with adjacent structures, such as ligaments and muscles, further confirming its connection to the ulna rather than other bones mentioned in the options.
