|Gray's||subject #200 887|
The lacrimal nerve is the smallest of the three branches of the ophthalmic.
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. 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.
