Frontalis Muscle

The Frontalis Muscle is a thin, paired muscle located in the forehead region of the face. It is part of the epicranius muscle, which also includes the occipitalis muscle. The frontalis muscle spans from the eyebrows to the top of the skull and is responsible for raising the eyebrows and creating horizontal wrinkles on the forehead. As one of the muscles involved in facial expressions, the frontalis plays a significant role in conveying emotions, such as surprise or curiosity. Its contraction allows for the lifting of the eyebrows and the smoothing or wrinkling of the forehead skin. Innervated by the facial nerve (cranial nerve VII), the frontalis muscle is vital for non-verbal communication and overall facial aesthetics. The careful balance between the frontalis and other facial muscles contributes to a wide range of expressive and dynamic facial movements.
