Comments

Johnson (1994) argues that the essentially transverse orientation of the upper and middle fibres of trapezius precludes any action as elevators of the scapula as commonly depicted. Instead, the action of these fibres is to raise the scapula by rotating the clavicle about the sternoclavicular joint or to draw the scapula and clavicle backwards.
