A system of human anatomy, general and special . the sympa-thetic filaments which accompany the ramifications of the two anteriorcerebral arteries. These filaments are derived from the carotid plexusat each side; and through their intervention, the ganglion of Ribes isbrought into connexion with the carotid plexus, and with the otherganglia of the sympathetic. This ganglion, though of very small size, is interesting, as being the superior point of union between the sym-pathetic chains of opposite sides of the body. The Ciliary Ganglion (lenticular) is a small quadrangular andflattened ganglion situated within the orbit, between the optic nerveand the external rectus muscle; it is in close contact with the opticnerve, and is surrounded by adipose tissue, which renders its dissec-tion somewhat difficult. 39* 462 CILIARY GANGLION. Its branches of distribution are the ciliary, which arise from itsanterior angles by two groups: the upper group, consisting of aboutfour filaments; and the lower, of five or six. They accompany the Fig. 188.*. ciliary arteries in a waving course, and divide into a number of fila-ments which pierce the sclerotic around the optic nerve, and supplythe tunics of the eyeball. A small filament is said by Tiedemann, to accompany the arteria centralis retinas into the centre of the globeof the eye. Its branches of communication are three, one, the long root, whichproceeds from the posterior superior angle to the nasal branch of theophthalmic nerve; a short thick branch, the short root, from the pos-terior inferior angle to the inferior division of the third nerve; and aslender filament, the sympathetic root, which passes backwards tothe cavernous sinus, and communicates with the carotid plexus.Occasionally the ciliary ganglion receives also a filament of commu- * The cranial ganglia of the sympathetic nerve. 1.
