Which of the following is not a primary action of the levator scapula muscle?

The main idea is understanding what levator scapulae does to the shoulder blade. This muscle primarily elevates the scapula, lifting the shoulder blade toward the ear. It also contributes to downward rotation of the scapula, which helps position the glenoid cavity downward when the arm moves. When the scapula is fixed, it can assist with lateral flexion of the neck on the same side. Depression of the scapula is not a primary action of this muscle. Other muscles, like the pectoralis minor and parts of the lower trapezius, are the ones mainly responsible for pulling the scapula downward. So, the action that is not a primary action of the levator scapula is depression of the scapula.
