The levator scapulae originates from the transverse processes of CI to CIV vertebrae (Fig. 7.36). It descends laterally to attach to the posterior surface of the medial border of the scapula from the superior angle to the smooth triangular area of bone at the root of the spine.
The levator scapulae muscle is innervated by the dorsal scapular nerve and directly from C3 and C4 spinal nerves.
The levator scapulae elevates the scapula.
