Which part of the trapezius adducts the scapula?

Explanation:
Adduction of the scapula, or scapular retraction, is produced mainly by the middle portion of the trapezius. These fibers run horizontally from the spine toward the medial border of the scapula and pull the scapula inward toward the spine, bringing the shoulder blades closer together. The upper fibers primarily elevate and upwardly rotate the scapula, while the lower fibers depress the scapula and assist with upward rotation. So, when you think of pulling the scapula toward the midline, you’re thinking of the middle fibers doing the adduction.
