Sinopsis

Excerpt from Quain's Elements of Anatomy, Vol. 3 of 3: Part II. The Nerves

There are four small ganglia connected with the divisions of the fifth nerve the ciliary ganglion with the first, the spheno-palatine ganglion with the second, and the otic and submaxillary ganglia with the third. These ganglia, besides receiving branches from the sensory part of the fifth, are each connected with a motor nerve from the third, the fifth, or the facial, and with twigs from the sympa thetic and the nerves thus joining the ganglia are named their roots.

The ciliary, ophthalmic, or lenticular ganglion serves as a centre for the supply of nerves - motor, sensory, and sympathetic - to the eyeball. It is a small reddish body, compressed laterally and somewhat four-sided, and measures about 2 mm. From before back. It is situated at the back of the orbit, between the outer rectus muscle and the optic nerve, and generally in contact with the Ophthalmic artery; it is joined behind by branches from the fifth, the third, and the sympa thetic nerves; while from its fore part proceed the short ciliary nerves to the eyeball. The cells of the ganglion are of the multipolar variety.
