Which muscle stabilizes and moves the scapula?

The action described—stabilizing and moving the scapula—depends on a large back muscle that anchors the shoulder blade to the thorax and coordinates its position during arm movements. The trapezius fits this role perfectly. It attaches from the skull and spine to the clavicle and scapula, and its fibers do different jobs: the upper fibers elevate the scapula, the middle fibers retract (pull the shoulder blade inward), and the lower fibers depress the scapula while helping rotate it upward. This combined action stabilizes the scapula and enables smooth shoulder movement, especially when lifting the arm. The other options are facial muscles that move features on the face (such as the nose or lips) and do not attach to or move the scapula, so they don’t influence shoulder blade stabilization or shoulder girdle mechanics.
