Verified step by step guidance

Step 1: Begin by understanding the term 'olecranon.' The olecranon is a specific anatomical structure located in the upper limb.
Step 2: Recall that the olecranon is part of the ulna, one of the two bones in the forearm. It forms the bony prominence at the elbow joint.
Step 3: Eliminate incorrect options by considering their anatomical locations. For example, the palm of the hand and wrist joint are located in the distal part of the upper limb, far from the elbow.
Step 4: Compare the remaining options. The shoulder blade (scapula) is part of the shoulder girdle, not the elbow region. This leaves the correct answer as the bony prominence of the elbow.
Step 5: Conclude that the olecranon is the bony prominence of the elbow, which serves as the insertion point for the triceps brachii muscle and plays a role in elbow extension.
