Superior Attachments and Relations
Above, the fascia is attached to the superior nuchal line of the occipital bone, to the mastoid process of the temporal bone, and to the whole length of the inferior border of the body of the mandible.
Opposite the angle of the mandible the fascia is very strong, and binds the anterior edge of the Sternocleidomastoideus firmly to that bone.
Between the mandible and the mastoid process it ensheathes the parotid gland—the layer which covers the gland extends upward under the name of the parotideomasseteric fascia and is fixed to the zygomatic arch.
From the part which passes under the parotid gland a strong band extends upward to the styloid process, forming the stylomandibular ligament.
Two other bands may be defined: the sphenomandibular and the pterygospinous ligaments.
The pterygospinous ligament stretches from the upper part of the posterior border of the lateral pterygoid plate to the spinous process of the sphenoid.
It occasionally ossifies, and in such cases, between its upper border and the base of the skull, a foramen is formed which transmits the branches of the mandibular nerve to the muscles of mastication.

Famous quotes containing the words superior and/or relations:
“The First Amendment is not a blanket freedom-of-information act. The constitutional newsgathering freedom means the media can go where the public can, but enjoys no superior right of access.”
—George F. Will (b. 1934)
“The land is the appointed remedy for whatever is false and fantastic in our culture. The continent we inhabit is to be physic and food for our mind, as well as our body. The land, with its tranquilizing, sanative influences, is to repair the errors of a scholastic and traditional education, and bring us to just relations with men and things.”
—Ralph Waldo Emerson (1803–1882)
