BRANCHES AND CONNECTIONS OF THE TRIGEMINUS. 



Serai-diagrammatic representation of the nerves of the eyeball, the connections of the trigeminus and 

 its ganglia, together with the facial and glosso-pharyngeal nerves. 3, Branch to the inferior oblique 

 muscle from the oculomotorius, with the thick short root, to the ciliary ganglion (c) ; t, ciliary 

 nerves ; I, long root to the ganglion from the naso-ciliary (nc) ; s, sympathetic root from the sym- 

 pathetic plexus (Sy) surrounding the internal carotid (G) ; d, first or ophthalmic division of the 

 trigeminus (5), with the nasociliary (nc), and the terminal branches of the lachrymal (a), supra- 

 orbital (b), and frontal (/) ; e, second or superior maxillary division of the trigeminus ; R, infra- 

 orbital ; n, spheno-palatine (Meckel's) ganglion with its roots ; j, from the facial, and v, from the 

 sympathetic ; N, the nasal branches, and pp x , the palatine branches of the ganglion ; g, third or 

 inferior maxillary division of the trigeminus ; k, lingual ; i i, chorda tympani ; m, otic ganglion, 

 with the roots from the tympanic plexus, the carotid plexus, and from the 3rd branch, and with its 

 branches to the auriculo-temporal (A), and to the chorda (i i) ; L, sub-maxillary ganglion with its 

 roots from the tympanico-lingual, and the sympathetic plexus on the external artery (q). 7, Facial 

 nerve y, its great superficial petrosal branch ; a, gang, geniculatum ; /3, branch to the tympanic 

 plexus ; 7, branch to the stapedius ; 8, anastomatic twig to the auricular branch of the vagus ; i i, 

 chorda tympani ; S, stylo-mastoid foramen. 9. Glosso-pharyngeal X, its tympanic branch ; tt and 

 , connections with the facial; U, terminations of the gustatory fibres of 9 in the circumyallate 

 papilla? ; Sy, sympathetic with G g, s, the superior cervical ganglion ; 7, II, III, J V, the four upper 

 cervical nerves ; P, parotid, M, sub-maxillary gland.
