解剖研究揭示了斜方肌的束状解剖。它的枕部和颈部纤维向下但主要是横向插入锁骨。颈-7和颈-1的纤维横过到达肩胛骨的肩峰和脊柱。它的胸纤维会聚到肩胛骨的三角肌结节。体积研究表明，颈-7、T-1和颈韧带下半部分的纤维最大。斜方肌的上部和中部纤维基本上是横向的，这就排除了通常所描述的作为肩胛骨升降机的任何作用。相反，这些纤维的作用是把肩胛骨和锁骨向后拉，或者通过旋转锁骨，使肩胛骨围绕胸锁关节上升。通过平衡力矩，斜方肌减轻了颈椎的压迫负荷。
Dissection studies revealed the fascicular anatomy of the trapezius. Its occipital and nuchal fibres passed downwards but mainly transversely to insert into the clavicle. Fibres from C-7 and T-1 passed transversely to reach the acromion and spine of the scapula. Its thoracic fibres converged to the deltoid tubercle of the scapula. Volumetric studies demonstrated that the fibres from C-7, T-1, and the lower half of ligamentum nuchae were the largest. The essentially transverse orientation of the upper and middle fibres of trapezius precludes any action as elevators of the scapula as commonly depicted. Rather the action of these fibres is to draw the scapula and clavicle backwards or to raise the scapula by rotating the clavicle about the sternoclavicular joint. By balancing moments the trapezius relieves the cervical spine of compression loads.
