iV 7 ". spheno-palatinus is a ramus from the maxillary nerve 5 mm. 

 peripherad of the round foramen ; it is one of the roots of the 

 spheno palatine ganglion. 



N. palatinus cephalicus is a ramus of the maxillary nerve just 

 peripherad of the sphenopalatine, and is distributed to the 

 rugae of the mouth and to the palate ; it also anastomoses 

 with the naso palatine nerve. 



JV. palatinus caudalis is an offset of the spheno-palatine gan- 

 glion, and is distributed to the soft palate and the rugreof the 

 mouth. 



JV. naso-palatinus is an offset of the same ganglion cephalad to 

 the turbinated bones ; its terminal filaments anastomose with 

 the cephalic palatine. 



NN. dentales are given off from the maxillary nerve just dorsad 

 of the alveoli, and, penetrating the bone, are distributed to 

 the maxillary teeth. 



JV. nasalis, N. labialis, N. palpebralis, are terminal filaments of 

 the maxillary nerve peripherad of the infra orbital foramen, 

 and are distributed to the side of the nose, to the papillae and 

 to the integument of the dorsal lip, the vibrissa?, the labial 

 plexus and the ventral lid. 



N. mdianus is a commissural nerve from the spheno-palatine 

 ganglion to the facial nerve through the petrosal nerve, N. ' 

 petrosus superficialis major. 

 {d) Rami of N. ophthalmicus: 



jV. frontalis : The origin is at the foramen lacerum anterius ; 

 the nerve becomes N. supra-orbitalis and N. supra-trochlearis ; 

 it is distributed to the forehead, the tactile hairs, the dorsal 

 lid, the conjunctiva, the lacus lachrymalis and the side of the 

 nose. 



JV. oculo-nasalis : The origin is at the foramen lacerum anterius ;. 

 it becomes the infra-trochlear and the caudal ethmoid nerves. 



N. ciliaris longus is a ramus at the border of the optic nerve ; 

 its termination is not demonstrated. 



N. ciliaris brevis is a ramus from the ophthalmic ganglion ; its 

 termination is with the long ciliary nerve. 



N. itifra trochlearis, a ramus at the border of the mesal rectus 

 muscle, is distributed to the trochlear muscle, the conjunctiva 

 and the integument of the dorsal lid, the lacus lachrymalis- 

 and the side of the nose. 



N. etlimoideus caudalis is the continuation of the trunk entad of 

 the ethmoid foramen ; it is distributed to the dura mater, to 

 the turbinated membrane ; it anastomoses with its platetrope, 

 and becomes the nervus externus, which is given to the sep- 

 tum nariuni and to the nasal cartilage.
