The prominent process on the proximal end of the ulna that forms the point of the elbow is the process.

The prominent process on the proximal end of the ulna that forms the point of the elbow is known as the olecranon process. The olecranon is a bony projection that plays a crucial role in the structure of the elbow joint. It serves as the attachment point for the triceps brachii muscle which is primarily responsible for elbow extension. This anatomical feature also helps in the formation of the elbow joint by articulating with the humerus at the trochlea, facilitating smooth movement during arm flexion and extension. Its prominence is important for the mechanical leverage necessary for effective movement and stability in the upper limb. Understanding the olecranon process is essential for studying the musculoskeletal system and for interpreting elbow injuries or conditions.
