zy·go·mat·ic nerve

[TA]
a branch of the maxillary nerve [CN V2] in the inferior orbital fissure through which it passes; it gives rise to two sensory branches, the zygomaticotemporal and zygomaticofacial, which supply the skin of the temporal and zygomatic regions and is continued as the communicating branch of the lacrimal nerve with the zygomatic nerve.
