	Ophthalmic nerve - Wikipedia, the free encyclopedia
		Nerves of the orbit, and the ciliary ganglion.
		The ophthalmic nerve is one of the three branches of the trigeminal nerve, the fifth cranial nerve.
		The ophthalmic nerve is joined by filaments from the cavernous plexus of the sympathetic, and communicates with the oculomotor, trochlear, and abducent nerves; it gives off a recurrent filament which passes between the layers of the tentorium.

	IX. Neurology. 5e. The Trigeminal Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
		The ciliary ganglion is connected with the ophthalmic nerve; the sphenopalatine ganglion with the maxillary nerve; and the otic and submaxillary ganglia with the mandibular nerve.
		It passes forward on the lateral side of the optic nerve, and enters the postero-superior angle of the ciliary ganglion; it is sometimes joined by a filament from the cavernous plexus of the sympathetic, or from the superior ramus of the trochlear nerve.
		The branches of the inferior alveolar nerve are the mylohyoid, dental, incisive, and mental.

		Two short nerves that suspend the pterygopalatine ganglion and pass through it to mingle with postganglionic fibers of the greater petrosal nerve and sympathetics of the deep petrosal nerve.
		This nerve emerges through the pterygo-maxillary fissure and supplies the mucous membrane of the maxillary sinus and the three molar teeth, and the vestibule beside the three molar teeth.
		This is a terminal branch of the maxillary division of the trigeminal nerve.

		The lacrimal gland is oriented in the superior-temporal region of the orbit and lies in the fossa glandular lacrimalis.
		The parasympathetic fibers travel from the lacrimal nucleus in the pons via the nervus intermedius to the greater superficial petrosal nerve, to the vidian nerve, to the sphenopalatine ganglion, to the zygomatic branch of the maxillary nerve, to the zygomaticotemporal nerve, to the lacrimal nerve to innervate the lacrimal gland.
		The orbital branches are the lacrimal artery, muscular arteries, and periosteal branches.

		Definition: Cranial nerve VII is a mixed nerve originating from cranial nuclei in the pons and medulla oblongata and distributing its branches to the derivatives of the 2nd branchial arch.
		The greater petrosal nerve, which is parasympathetic, exits the middle ear from a foramen with the same name, follows a groove for the greater petrosal nerve and joins the deep dorsal petrosal nerve (sympathetic) upon entry into the pterygoid canal to form the Nerve of pterygoid canal (now both sympathetic and parasympathetic).
		The lingual nerve (plates 41,55, Netter) runs medially to the inferior alveolar nerve between the lateral and medial pterygoids and enters the sublingual space, where the parasympathetic fibers synapse at the submandibular ganglion to provide parasympathetic postsynaptic innervation for the submandibular and sublingual glands, and the afferents innervate the anterior 2/3 of the tongue.

	Yale- Cranial Nerve 7, pg. 17
		The greater petrosal nerve passes deep to the trigeminal ganglion to enter the foramen lacerum.
		The nerve traverses the foramen and enters a canal at the base of the medial pterygoid plate in conjunction with sympathetic fibers (deep petrosal nerve) branching from the plexus following the internal carotid artery.
		Upon exiting the pterygoid canal, pre-ganglionic parasympathetic fibers of CN VII synapse in the pterygopalatine ganglion which is suspended from the fibers of the maxillary division of the trigeminal nerve (V2) in the pterygopalatine fossa.

	eMedicine - Arterial Supply, Orbit : Article by Hon-Vu Q Duong, MD
		As the artery crosses the optic nerve, it is accompanied by the nasociliary nerve and is separated from the frontal nerve by the superior rectus muscle and the superior levator palpebral muscle.
		The lacrimal artery sometimes is derived from one of the anterior branches of the middle meningeal artery.
		The inferior medial palpebral artery anastomoses with the lower of the 2 lateral palpebral branches from the lacrimal artery at the lateral angle of the orbit; with the transverse facial artery; and, at the medial part of the eyelid, with a branch from the angular artery.

	ICP monitors
		The greater petrosal nerve may be pulled on in the middle cranial fossa with consequent pressure on VII and a temporary facial paresis.
		The nerve is joined by postganglionic secreto-motor fibers which innervate the five territories of the ganglion (nasal septum, lateral nasal wall, paranasal sinuses, hard and soft palates, and the nasopharynx).
		The lacrimal gland fibers follow a circuitous route by entering the orbit via the zygomatic branch of V2, and then transferring to the lacrimal nerve of V1 which innervates the gland.
