|Anatomical terms of neuroanatomy|
The lacrimal nerve is occasionally absent, and its place is then taken by the zygomaticotemporal branch of the maxillary nerve. Sometimes the latter branch is absent, and a continuation of the lacrimal nerve is substituted for it.
The zygomatic nerve carries sensory fibers from the skin and mucous membranes. 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.
