Which forehead muscle is involved in raising the eyebrow?

Explanation:
The frontalis muscle on the forehead is responsible for raising the eyebrows. It runs from the galea aponeurotica down to the skin of the brows; when it contracts, it pulls the skin upward, lifting the eyebrows and creating horizontal forehead folds. The other muscles perform different actions: the zygomaticus elevates the corners of the mouth (smile), the orbicularis oculi closes the eyelids, and the corrugator draws the eyebrows together and downward. So, lifting the eyebrows specifically points to the frontalis.
