The zygomatic process of the temporal arises by two roots: * an ''anterior'', directed inward in front of the [[mandibular fossa]], where it expands to form the articular tubercle. * a ''posterior'', which runs backward above the [[external acoustic meatus]] and is continuous with the supramastoid crest. The upper border of the arch gives attachment to the [[temporal fascia]]; the lower border and medial surface give origin to the [[Masseter]]. ==Additional images== <gallery> Image:Gray137.png|Left temporal bone.
