The zygomatic nerve is not to be confused with the zygomatic branches of the facial nerve . Structure The zygomatic nerve arises in the pterygopalatine fossa . It enters the orbit by the inferior orbital fissure , and divides at the back of that cavity into two branches, the zygomaticotemporal nerve and zygomaticofacial nerve . The zygomatic nerve carries sensory fibers from the skin. It also carries post synaptic parasympathetic fibers originating in the pterygopalatine ganglion to the lacrimal nerve via a communication. These fibers will eventually provide innervation to the lacrimal gland .These parasympathetic fibers come from the facial cranial nerve which is the seventh CN.
