Maxillary division of Trigeminal nerve (V2 or Vb) / Maxillary nerve
Courses anteriorly low in the lateral wall of the cavernous sinus inferior to trochlear nerve. Just before exiting the skull it runs along the floor of the middle cranial fossa and gives off the middle meningeal nerve which ascends to supply the anterior dura of the middle cranial fossa. It then passes through the foramen rotunda in the greater wing of the sphenoid bone to exit skull and enter the superior aspect of the pterygopalatine fossa. It gives branches to pterygopalatine ganglion but also receives parasympathetic nerves from the ganglion via the greater petrosal nerve. It then divides into the:
zygomatic nerve (inferior orbital fissure)
zygomaticotemporal nerve (zygomaticotemporal foramen)
zygomaticofacial nerve (zygomaticofacial foramen)
infraorbital nerve (inferior orbital fissure then infraorbital foramen)
posterior superior alveolar nerve (pterygomaxillary fissure)
middle superior alveolar nerve
anterior superior alveolar nerve
nasopalatine nerve (sphenopalatine foramen)
posterior superior nasal nerves (sphenopalatine foramen)
greater palatine nerve (greater palatine foramen)
lateral posterior inferior nasal nerve (un-named foramina)
lesser palatine nerve (lesser palatine foramen)
pharyngeal nerve (palatovaginal canal)
