Levator Scapulae Lateral Attachment | medial border of scapula between superior angle and root of spine |
Levator Scapulae Action(s) with the medial attachment (or trunk) fixed | elevation of the scapula |
Levator Scapulae Action(s) with the lateral attachment fixed | unilaterally: - lateral flexion - same side rotation bilaterally: - extension of cervical spine - |
Serratus Anterior Medial Attachment | costal (anterior) surface of medial border of scapula |

Pectoralis Minor Innervation | pectoral (C8-T1) |
Trapezius Action(s) (Upper Muscle Fibers) | with the medial attachment (or trunk) fixed: - upward rotation - elevation - stabilization with the lateral attachment or scapula fixed: - unilaterally: extension, lateral flexion, & opposite side rotation -bilaterally: extension of the neck |
Trapezius Action(s) (Middle Muscle Fibers) | abduction of the scapula |
Trapezius Action(s) (Lower Muscle Fibers) | with the medial attachment (or trunk) fixed: - upward rotation - depression - stabilization with the lateral attachment or scapula fixed: - none |
