Description
The epicranial aponeurosis connects the occipital and frontal portions of the occipitofrontalis muscle, thus forming a continuous sheet. Posteriorly, it blends with the occipital belly of the occipitofrontalis to insert into the superior nuchal line of the occipital bone. Anteriorly, it encloses the frontalis portion of the occipitofrontalis muscle and blends with the eyebrows. Laterally, it blends with the temporalis fascia, as well as the anterior and superior auricular muscles and the temporoparietalis muscle.
The epicranial aponeurosis is tightly bound to the overlying skin via a fibrous superficial fascia. However, it is loosely connected to the underlying pericranium, thus allowing it to move freely, while carrying the skin with it.
