the origin of the frontalis muscle is at galea aponeurotica.
where is the origin of the frontalis muscle?
galea aponeurotica
from these attachments the fibers are directed upward, and join the galea aponeurotica below the coronal suture.





























the medial margins of the frontalis muscles are joined together for some distance above the root of the nose; but between the occipitales there is a considerable, though variable, interval, occupied by the galea aponeurotica.





























section::::function.





























in humans, the frontalis muscle only serves for facial expressions.





























in the eyebrows, its primary function is to lift them (thus opposing the orbital portion of the orbicularis), especially when looking up. it also acts when a view is too distant or dim.

the frontalis muscle is supplied by the facial nerve and receives blood from the supraorbital and supratrochlear arteries.
