Zygomatic arch
The zygomatic arch or cheek bone is formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone , the two being united by an oblique suture; the tendon of the Temporalis passes medial to the arch to gain insertion into the coronoid process...

Boundaries
- Medial: Os frontale, os parietale, os temporale, os sphenoidale, os occipitale (bones of neurocranium).
- Lateral: Temporal fascia
- Anterior: Posterior surface of the frontal process of the zygomatic bone and the posterior surface of the zygomatic process of the frontal bone.
- Superior: Pair of temporal lines (superior and inferior temporal lines) that arch across the skull from the zygomatic process of the frontal bone to the supramastoid crest of the temporal bone
- Inferior: Zygomatic arch laterally and by the infratemporal crest of the greater wing of the sphenoid medially.
