Wikipedia
The zygomatic nerve (temporomalar nerve; orbital nerve) is a branch of the maxillary nerve (a trigeminal nerve branch) that enters the orbit and helps to supply the skin over the zygomatic and temporal bones.
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 parasymphatetic fibers come from the facial cranial nerve which is the seventh CN.
