 Fig. n. THE COURSE, RELATIONS, AND DISTRIBUTION OF THE CRANIAL NERVES. 

 i, Optic nerve. 2, The internal carotid artery. 3, The sixth cranial nerve. 4, Third 

 cranial nerve. 5, Fourth cranial nerve. 6, Fifth cranial nerve, with the Gasserian 

 ganglion. Its divisions into the ophthalmic, superior maxillary, and inferior maxil- 

 lary branches is clearly shown. The course of these branches with their terminal 

 divisions or distributions can easily be traced. To indicate each small branch on the 

 photograph would ruin it. 7, The facial nerve. The geniculate ganglion and branches, 

 the chorda tympani (passing downward and forward to join the gustatory nerve), and the 

 terminal divisions and their branches are all shown. 8, Spinal accessory passing upward 

 to the foramen magnum. 9, Same nerve in the neck. 10, Pneumogastric nerve, 

 n, Glosso-pharyngeal nerve. 12, Internal carotid artery. Notice the various sympa- 

 thetic plexuses upon it. 13, Superior cervical ganglion. 14, Ophthalmic ganglion. 

 15, Supra-orbital nerve. 16, Lachrymal gland. 17, Meckel's ganglion. 18, Infra-orbital 

 nerve. 19, Mental nerve. 20, Internal pterygoid muscle. 21, Frontal sinus. The 

 student is urged to study the relations within the orbit and the three great trunks of the 

 fifth nerve.
