temporal line

The superior or the inferior temporal line. The superior temporal line is an arching ridge along the lateral surface of the skull; it begins as a continuation of the upper posterior border of the zygomatic bone and continues as a broad arch along the frontal and parietal bones, above and roughly parallel to the upper edge of the temporal bone. The inferior temporal line begins with the superior temporal line and separates from its lower edge to form a parallel but tighter and lower arch. The inferior temporal line marks the origin of the temporalis muscle; the superior temporal line marks the attachment of the muscle's fascia.
