Primary action of levator scapulae?

Explanation:
Levator scapulae mainly elevates the scapula, lifting its medial border toward the neck. Because it attaches to the superior angle of the scapula, when it shortens it also pulls the scapula in a way that rotates the glenoid cavity downward. So the primary actions are elevation of the scapula and downward rotation. This distinguishes it from muscles that protract (serratus anterior) or upwardly rotate (upper trapezius and serratus anterior).
