attached to dorsal to overlaps muscles innervated by the facial nerve skin of body A muscle of the skin of the head (scalp), innervated by the facial nerve, attached to facia of the skin superior to the orbits (superciliary region), overlapping with the procerus muscles, and attched to the facia of the scalp (galea aponurotica or epicranial aponeurosis in humans). In mammals other than humans, there is no large facia present and the most rostral fibers of the occipitalis are attached to the skin near or even overlapping with the fibers of the frontalis muscle.See Diogo 2008; Diogo et al., 2009; Burrows et al.., 2011. frontalis muscle procerus muscle orbit scalp
