What muscle is responsible for the movement of the shoulders and the shoulder blades?
As the name of the muscle suggests, the actions of the levator scapulae are mainly on the movement of the shoulders and the shoulder blades (the scapula). When the levator scapulae muscle contracts, the act of scapular elevation (i.e. shoulder raising) is performed. You can easily demonstrate this yourself by shrugging your shoulders.

What is the function of the levator scapulae?
Function. When the spine is fixed, levator scapulae elevates the scapula and rotates its inferior angle medially. It often works in combination with other muscles like the rhomboids and pectoralis minor to produce downward rotation of the scapula.
What are the muscles of the shoulder?
The muscles of the shoulder can be categorized into three topographic units: the scapulohumeral, axiohumeral, and axioscapular groups. Levator scapulae forms part of the latter group together with rhomboid major, rhomboid minor, serratus anterior, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs). The serratus anterior formed the basal unit for these three muscles. In higher primates it has evolved into two separate muscles — serratus anterior and levator scapulae — by concentration of the proximal and distal fibers and progressive reduction of the intermediate fibers. The fibers concerned with the cranial displacement of the scapula became the levator scapulae.
What happens when the scapulae are fixed?
When the shoulder is fixed, levator scapulae rotates to the same side and flexes the cervical spine laterally. When both shoulders are fixed, a simultaneous co-contraction of both levator scapulae muscles in equal amounts would not produce lateral flexion or rotation, and may produce straight flexion or extension of the cervical spine.

What is the name of the nerve that causes paralysis of the levator scapulae?
An isolated lesion of the dorsal scapular nerve with a consequent paralysis of the levator scapulae muscle is very rare. The symptoms include “winging” of the scapula (scapula alata), as well as atrophy of both the levator scapulae and rhomboid muscles.
