All of the following muscles are used for the retraction of scapula, EXCEPT:
The levator scapula muscle attaches to the cervical veebrae and the superior angle of the scapula, causing elevation and downward rotation of the scapula. Trapezius elevates, retracts, depresses, and rotates scapula. The rhomboid muscles attach to the spinous processes of C7-T5 and the medial border of the scapula, resulting in scapular retraction.
