Retraction= Middle trapezius Elevation= Upper trapezius
The trapezius muscle in humans is a single, large muscle divided into three specific regions based on their functions: the upper trapezius, middle trapezius, and lower trapezius. Each region of the trapezius muscle contributes to different movements of the shoulder and neck.
The rhomboid muscles and the middle trapezius muscle pull the scapulae medially. These muscles work together to retract and stabilize the scapulae toward the spine.
The middle trapezius will hurt if the muscle has been pulled or strained. The way to properly heal it is to try massaging the part of the trapezius that hurts the most, in order to work out the kinks. If that doesn't help after a few months, then physical therapy is needed.
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.
The trapezius muscle has three parts: the upper fibers (descending from the skull to the upper back), the middle fibers (running horizontally across the upper back), and the lower fibers (ascending from the middle back to the shoulder blades).
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
The muscle located in the upper part of your back in the middle is called the trapezius muscle. It is a large, triangular muscle that extends from the base of your skull down to the middle of your spine and across to your shoulders. Its primary function is to move and stabilize the shoulder blades.

trapezius
The Trapezius muscles are involved in upward rotation of the scapula. However Trapezius is agonist/antagonist to itself as the upper portion elevates the scapula, the middle portion adducts the scapula and the lower portion depresses the scapula, while all parts are involved in upward rotation of the scapula. The Serratus Anterior assists in rotating the scapula (glenoid fossa) upward, (which would make it a synergist with the trapezius). The Serratus Anterior is antagonist to the upper and middle portions of Trapezius, so we are back to the agonist /antagonist relationship of the traps. That's about all I can contribute to this question.
Yes, the trapezius muscle is commonly referred to as the traps.
