====== Galea aponeurotica ======
{{ ::galeaaponeurotica.gif|}}
The galea aponeurotica (epicranial aponeurosis, aponeurosis epicranialis) is a tough layer of dense fibrous tissue that covers the upper part of the [[cranium]]; behind, it is attached, in the interval between its union with the occipitales, to the [[external occipital protuberance]] and highest nuchal lines of the [[occipital bone]]; in front, it forms a short and narrow prolongation between its union with the Frontales.

On either side it gives origin to the Auriculares anterior and superior; in this situation, it loses its aponeurotic character and is continued over the temporal fascia to the zygomatic arch as a layer of laminated areolar tissue.

It is closely connected to the integument by the firm, dense, fibro-fatty layer which forms the superficial fascia of the scalp: it is attached to the [[pericranium]] by loose cellular tissue, which allows the aponeurosis, carrying with it the integument to move through a considerable distance.
