Under the first definition,<unk>  is a band of fibrous tissue which connects the humeral and the ulnar heads of the FCU. It can be classified as being thin or thick and thought to be a separate structure from the aponeurosis of the FCU. Under the second definition,<unk>  is a<unk> ous tissue with one end attached to the olecranon and the other to the medial epicondyle. It is generally believed to be analogous to the anatomically variant epitrochleoanconeus muscle which is attached to the olecranon and the medial epicondyle in the same manner, meaning that people possessing<unk>  do not have the epitrochleoanconeus and vice versa. It can be categorized into two types: * Type Ia: thin; lax when the elbow is extended and becomes taut when the elbow is flexed. * Type Ib: thick; taut even when the elbow is not fully flexed (90°–120°). Under both definitions,<unk>  forms the roof of the cubital tunnel, an opening between the muscles through which the ulnar nerve passes.
