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 .
Lumboinguinal nerve (green) and Ilioinguinal nerve (purple). In modern texts, these two regions are often considered to be innervated by the genitofemoral nerve. Medial cluneal nerves (pink) - labeled as "post. division of sacral" Inferior cluneal nerves (pink region, not designated with its own section)

The zygomaticofacial foramen is a small [citation needed] opening upon the lateral (facial) surface of the zygomatic bone near the bone's orbital border. It gives passage to the zygomaticofacial nerve, artery, and vein. It is often doubled; it is sometimes absent. [1]
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
A neuron (also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signaling. Neurons are the core components of the brain, spinal cord, and peripheral nerves. Soma; Axon; Myelin; Dendrite; Dendritic spine
