  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.
Nerves of the orbit, and the ciliary ganglion.
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 nerves for the muscles of the nose are derived from the facial, while the skin receives branches from the infratrochlear and nasociliary branches of the ophthalmic, and from the infraorbital of the maxillary.
The nerves of ordinary sensation are: the nasociliary branch of the ophthalmic, filaments from the anterior alveolar branch of the maxillary, the nerve of the pterygoid canal, the nasopalatine, the anterior palatine, and nasal branches of the sphenopalatine ganglion.
The nasociliary branch of the ophthalmic distributes filaments to the forepart of the septum and lateral wall of the nasal cavity.

 IX. Neurology. 5c. The Oculomotor Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
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.

Nasociliary Nerve: Intermediate in size and enters the orbit through the medial part of the superior orbital fissure between the two divisions of the oculomotor nerve.
There are five branches of the nasociliary nerve, the ramous communication to the ciliary ganglion, two long ciliary nerve, the infratrochlear nerve, the posterior ethmoidal nerve and anterior ethmoidal nerve.
The long ciliary nerves arise from the nasociliary nerve as it crosses the optic nerve and pierces the sclera of the eyeball close the optic nerve to be distributed to the ciliary body, iris and cornea.

36 Its sensory root is derived from two sphenopalatine branches of the maxillary nerve; their fibers, for the most part, pass directly into the palatine nerves; a few, however, enter the ganglion, constituting its sensory root.
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.
They correspond in number to the roots of those teeth; each nerve entering the orifice at the point of the root, and supplying the pulp of the tooth; above the alveolar nerve they form an inferior dental plexus 72 The incisive branch is continued onward within the bone, and supplies the canine and incisor teeth.

 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.

 Trigeminal nerve 1
The sensory branches that pertain to the oral cavity are the: buccal nerve, lingual nerve, inferior alveolar nerve, mental nerve and the incisive nerve (Gray, 1918).
Lastly, the inferior alveolar nerve is very important to the oral cavity because it serves the mandibular teeth, and the facial gingiva of the mandibular anterior teeth and premolars (Gray, 1918).
The nerves that are mentioned above are afferent nerves that belong to the sensory root of the mandibular division and convey sensory information for the lower cheeks, lower lip and the anterior portion of the mandible.

HZO is manifested by localized pain over the distribution of the first division of the trigeminal nerve, followed by a cutaneous vesicular eruption over the forehead, lymph node enlargement in the drainage areas, fever, malaise, headache, sometimes neck stiffness, and a red eye.
In 1864, Hutchinson correctly proposed that cutaneous involvement in the distribution of the nasociliary nerve heralds ocular involvement.
Nerve damage may be associated with neurotrophic (neuroparalytic) keratitis, some ocular motor palsies, and neuralgia.

All four receive sensory filaments from the trigeminal, and motor and sympathetic filaments from various sources; these filaments are called the roots of the ganglia.
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.
—The sphenopalatine ganglion, the largest of the sympathetic ganglia associated with the branches of the trigeminal nerve, is deeply placed in the pterygopalatine fossa, close to the sphenopalatine foramen.

It controls the ciliary muscle (affecting accommodation), and all extrinsic eye muscles except for the superior oblique muscle and the lateral rectus muscle.
It supplies somatic motor fibers to all the ocular muscles, except the Obliquus superior and Rectus lateralis; it also supplies through its connections with the ciliary ganglion, sympathetic motor fibers to the Sphincter pupillæ and the Ciliaris muscles.
The nucleus of the oculomotor nerve doesn't consist of a continuous column of cells, but is broken up into a number of smaller nuclei, which are arranged in two groups, anterior and posterior.
