The proximal part of the ulna extends beyond the articulation with the humerus forming the ''olecranon process''; known anatomically as the point of the elbow. The olecranon allows the bony attachment of the triceps. Slightly distal to the olecranon the cranial margin articulates with the ''anconeal process'' (see above) which fits into the olecranon fossa of the distal humerus. Slightly distal to the anconeal process and trochlear notch of the humerus are the lateral and medial coronoid processes which also facilitate muscular attachments and collateral ligaments of the elbow. The ulna runs the full length of the radius and is seperated from the radius by aninterosseous space that in canines is filled with a membrane.
