| Anatomical terms of muscle | |
The frontalis muscle (from Latin 'frontal muscle') is a muscle which covers parts of the forehead of the skull. Some sources consider the frontalis muscle to be a distinct muscle. However, Terminologia Anatomica currently classifies it as part of the occipitofrontalis muscle along with the occipitalis muscle.[2]
In humans, the frontalis muscle only serves for facial expressions.[3]
The frontalis muscle is supplied by the facial nerve[4] and receives blood from the supraorbital and supratrochlear arteries.
