Besides these specialarteries, numerous mi-nute vessels enter theiris ftom the ciliaryprocesses. The veins of the iris follow closely the arrangement of the arteriesjust described. The canal of Schlemm communicates with this systemof vessels. Nerves of the choroid and iris.—The ciliary nerves (fig. 384),about fifteen in number, and derived from the lenticular ganglion andthe nasal branch of the ophthalmic division of the fifth nerve, piercethe sclerotic near the entrance of the optic nerve, and come immediatelyinto contact with the c
