structure notes
  • 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
taxon notes
  • The zygomatic arch is significant in evolutionary biology, as it is part of the structures derived from the ancestral single temporal fenestra of the synapsid ancestor of mammals.
terminology notes
  • The zygomatic arch is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic process.
