epicranius [Gk, epi + kranion, skull] , the broad muscular and tendinous layer of tissue covering the top and sides of the skull from the occipital bone to the eyebrows. It consists of broad, thin muscular bellies, connected by an extensive aponeurosis. Innervation of the epicranius by branches of the facial nerves can draw back the scalp, raise the eyebrows, and move the ears. Compare epicranium. See also epicranial aponeurosis, occipitofrontalis, temporoparietalis.
