GROSS ANATOMY

Detailed explanation-1: -The olecranon process is the large, blunt, proximal tip of the ulna. The rough posterior surface of the olecranon process is the distal attachment for the triceps muscles.

Detailed explanation-2: -The olecranon is the tip of the ulna and serves as the insertion point for the triceps muscle-which straightens the elbow. The triceps muscle inserts into the olecranon process of the elbow and straightens the elbow. The biceps inserts into the radius and bends the elbow.

Detailed explanation-3: -The proximal end of the ulna which forms the tip of the elbow is called the Olecranon process. This process is the site of attachment of the tricep muscle tendons. Its contraction is involved in elbow straightening.

Detailed explanation-4: -The olecranon is the part of the ulna that cups the lower end of the humerus, creating a hinge for elbow movement. The bony point of the olecranon can easily be felt beneath the skin because it is covered by just a thin layer of tissue.
