What is the role of the auricularis superior muscle?

The auricularis superior muscle is primarily responsible for the movement of the ear, specifically for drawing the ear upward. This muscle is part of a group of muscles known as the auricular muscles, which are involved in the mobility of the ear. Although many people may not have a significant ability to consciously move their ears, these muscles are still present and play a role in fine-tuning the positioning of the ears in response to sound.

The options related to closing the eyelid and raising the upper lip refer to different muscle groups, such as the orbicularis oculi and the zygomaticus major, respectively. These muscles have distinct functions and are not related to the movement of the ear. Therefore, the role of the auricularis superior muscle aligns specifically with ear movement, making it the correct answer.
