Which muscle is responsible for raising the eyebrows?

The muscle responsible for raising the eyebrows is the frontalis. This muscle, located on the forehead, plays a critical role in facial expressions. When the frontalis contracts, it lifts the skin of the forehead and elevates the eyebrows, which may convey surprise or curiosity.

In contrast, the orbicularis oculi is primarily involved in closing the eyelids, the masseter is a major muscle used for chewing and is located in the jaw, and the temporalis assists in moving the jaw but does not affect the eyebrows. Understanding the specific functions of these facial muscles is essential for professionals in cosmetology, as it allows them to appreciate how various expressions are created and how to enhance facial aesthetics effectively.
