The epicranius muscle, also known as the occipitofrontalis, primarily functions to support scalp movement. It consists of two muscle bellies: the occipitalis at the back of the head and the frontalis at the front. Together, these muscles allow for the movement of the scalp, such as raising the eyebrows or wrinkling the forehead. The ability to move the scalp contributes to various facial expressions but is not primarily focused on facial expressions themselves. Rather, the function of the epicranius is more aligned with the movement and positioning of the scalp, making its primary focus support for any actions involving the upper head and forehead.
