	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.

	CHAPTER 45: THE ORBIT
		The ophthalmic nerve, the first division of the trigeminal (fifth cranial) nerve, is a wholly afferent nerve that supplies the globe and conjunctiva, lacrimal gland and sac, nasal mucosa and frontal sinus, external nose, upper eyelid, forehead, and scalp, It arises from the trigeminal ganglion which contains the cell bodies of its sensory nerve fibers.
		The nasociliary nerve is the sensory nerve to the eyeball and is accompanied by the ophthalmic artery.
		The terminal branches of the ophthalmic artery are the supratrochlear and dorsal nasal arteries.

	Trigeminal nerve - Wikipedia, the free encyclopedia
		The ophthalmic nerve carries sensory information from the scalp and forehead, the upper eyelid, the conjunctiva and cornea of the eye, the nose (including the tip of the nose), the nasal mucosa, the frontal sinuses and parts of the meninges (the dura and blood vessels).
		The mandibular nerve carries sensory information from the lower lip, the lower teeth and gums, the floor of the mouth, the anterior ⅔ of the tongue, the chin and jaw (except the angle of the jaw, which is supplied by C2-C3), parts of the external ear, and parts of the meninges.

	IX. Neurology. 1F. The Abducent Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
		The abducent nerve is joined by several filaments from the carotid and cavernous plexuses, and by one from the ophthalmic nerve.
		As these nerves pass forward to the superior orbital fissure, the oculomotor and ophthalmic divide into branches, and the abducent nerve approaches the others; so that their relative positions are considerably changed.
		Below the optic nerve are the inferior division of the oculomotor, and the abducent, the latter lying on the medial surface of the Rectus lateralis.

		The fibers of the oculomotor nerve arise from a nucleus which lies in the gray substance of the floor of the cerebral aqueduct and extends in front of the aqueduct for a short distance into the floor of the third ventricle.
		On emerging from the brain, the nerve is invested with a sheath of pia mater, and enclosed in a prolongation from the arachnoid.
		One passes beneath the optic nerve to the Rectus medialis; another, to the Rectus inferior; the third and longest runs forward between the Recti inferior and lateralis to the Obliquus inferior.

		The anteromedial branch of the inferolateral trunk accompanies the abducent nerve.
		For example, in adults the dural pore of the oculomotor nerve is mostly situated at the level of the posterior clinoid process or even far behind this process.[20] In contrast, the infant dural pore is always situated in front of the posterior clinoid process (on average 3.99 mm).

		At its termination, the nerve lies beneath the Quadratus labii superioris, and divides into a leash of branches which spread out upon the side of the nose, the lower eyelid, and the upper lip, joining with filaments of the facial nerve.
		It lies at first beneath the Pterygoideus externus, medial to and in front of the inferior alveolar nerve, and is occasionally joined to this nerve by a branch which may cross the internal maxillary artery.
		The fibers from the glossopharyngeal which pass to the otic ganglion in the small superficial petrosal are supposed to be sympathetic efferent (preganglionic) fibers from the dorsal nucleus or inferior salivatory nucleus of the medulla.

	Ophthalmic Echography
		Ophthalmic Ultrasound, also referred to as echography, is an imaging technique useful in the evaluation of intraocular structures when ophthalmoscopic evaluation is limited or totally obscured.
		It has also been proven to be useful in the evaluation and differentiation of intraocular tumors, orbital tumors, extraocular muscle disorders, as well as retrobulbar optic nerve disease.
		Ophthalmic echography is also used to obtain measurments of the eyes to aid in the determination of intraocular lens power for patients undergoing cataract extraction and placement of an artificial lens.

		An optic nerve sheath fenestration is a procedure now performed almost exclusively to treat patients with pseudotumor cerebri.
		Once the surgeon gains access to the optic nerve, a small “window” is created in the optic nerve sheath using delicate instruments.
		Unfortunately, some studies suggest that an optic nerve sheath fenestration may not be a permanent panacea to the deleterious effects of pseudotumor cerebri on the optic nerve.

	Des'Tyn'Nee - Trigeminal nerve
		The trigeminal nerve is the fifth (V) cranial nerve, and carries sensory information from most of the face, as well as motor supply to the muscles of mastication (the muscles enabling chewing), tensor tympani (in the middle ear), and other muscles in the floor of the mouth, such as the mylohyoid and anterior digastric muscle.
		The trigeminal nerve is the major cutaneous sensory nerve of the head, and is responsible for sensation over most of the skin on the head.
		The mandibular nerve supplies motor fibres to the temporalis, lateral pterygoid, medial pterygoid, masseter (the four main muscles involved in mastication), tensor veli palatini, mylohyoid, the anterior belly of the digastric muscle, and the tensor tympani.
