temporal fascia

The temporal fascia is a strong, glistening membrane which is stretched over the temporal fossa, binding down the temporal muscle. Superiorly, it is attached to the upper temporal line. Inferiorly, it splits into two laminae which are separated from each other by fat which contains some small vessels. The superficial lamina is attached to the upper border of the zygomatic arch, and the other is continuous with the fascia on the deep surface of the upper part of the masseter.
