Retraction= Middle trapezius Elevation= Upper trapezius
trapezius
The trapezius is an upper back/neck muscle and the deltoids are shoulder muscles
A number of muscles are involved in shrugging your shoulders, including the latissiumus dorsi, the deltoids, the rhomboids, the scapular muscles, the biceps, the triceps, among others. The primary muscle is the upper trapezius muscle. The secondary muscles are the middle trapezius muscles and the levator scapulae.

You can't have one muscle that both elevates AND depresses a bone. So your question is a little confusing, Upward rotation: Serratus anterior, Upper and lower fibers of trapezius Retraction (adduction): Middle fibers of trapezius, rhomboid major and minor Elevation: Upper fibers of trapezius, levator scapulae, rhomboid major and minor Depression: Lower fibers of trapezius Let me know if I left any out but this should be all of them! Trevor .............................. the above answer is incomplete........ The trapezius is antagonist to itself, in that it can both elevate and depress the scapula
Latissimus dorsi, Trapezius, the 2 Rhomboideus
Trapezius - it elevates and depresses the scapula.

The trapezius raises scapulaas when shrugging shoulders, and pulls head backwards.
