In protraction and retraction, retraction refers to which movement?

Explanation:
Retracting the shoulders means pulling the shoulder blades toward the spine, bringing the scapulae closer together. This is adduction of the scapula and is mainly produced by the rhomboid muscles and the middle fibers of the trapezius. It contrasts with protraction (pushing the shoulders forward, away from the spine) which is driven by the serratus anterior and parts of the pectoral muscles. Upward rotation of the scapula is a different movement that occurs when raising the arm, not retraction. Tilting the head sideways is unrelated to scapular movement. In practical terms, retraction is what you do when you squeeze your shoulder blades together.
