Anatomical terms of neuroanatomy

The zygomatic nerve is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)). It arises in the pterygopalatine fossa and enters the orbit through the inferior orbital fissure before dividing into its two terminal branches: the zygomaticotemporal nerve and zygomaticofacial nerve.

Through its branches, the zygomatic nerve provides sensory invervation to skin over the zygomatic bone and the temporal bone. It also carries post-ganglionic parasympathetic axons to the lacrimal gland.

It may be blocked by anaesthetising the maxillary nerve.
