The olecranon is a part of which bone?

The olecranon is a specific anatomical feature located at the proximal end of the ulna, which is one of the two bones in the forearm. It forms the bony prominence of the elbow and serves as a crucial site for muscle attachment, particularly for the triceps brachii. The olecranon plays an essential role in the functioning of the elbow joint, facilitating movement and stability. Understanding its location on the ulna is key to comprehending how the upper limb mechanics work, particularly in actions involving the arm and forearm.
