^3 6 NEUROLOGY. 



temporo-maxillary articulation, and is distributed to the masseter 

 KDUscle. It gives ofif branches to the temporal muscle. 



The buccal nerve is directed forwards, traverses the external 

 pterygoid muscle, and is distributed to the buccinator muscle and 

 tiD the mucous membrane of the cheek, descending to the com- 

 :Hiiissures of the lips and the labial glands. In its course it gives 

 small branches to the external pterygoid mruscle, a branch (the 

 smterior deep temporal nerve) to the temporal muscle, and branches 

 :to the molar glands. The branches to the pterygoid and temporal 

 muscles are for the most part motor, the others sensory. 



The pterygoid nerve supplies the pterygoid muscles. 



The subzygomatic or superficial temporal rterve winds round 

 Ihe ramus of the lower jaw, and, passing between the parotid 

 •gland and the posterior border of the jaw, joins the uerves of the 

 seventh pair. In its ^course it gives off twigs to the guttural 

 jpouch, parotid gland, and teguments of the temporal region. 



The lingual, considered by some authorities as the gvustcdory 

 -OT nerve of the special sense of fasten is the principal branch of 

 -the inferior maxillary ; its course lies between the ramus of the 

 jaw and the pterygoid muscles, round which it winds anteriorly, 

 to reach the base of the tongue, along the side of which, under 

 "the mucous membrane, it runs to the tip, giving off in its course 

 :iiumerous branches to the lingiial papillae, the mucous membrane 

 of the mouth and gums, and the sublingual gland. The lingual 

 xeceives the chorda tympani branch of the facial, and anastomoses 

 T^ith terminal branches of the twelfth nerve ; it also sends a 

 branch to the submaxillary ganglion. 



The mylo-hyoidean nerve distributes branches to the mylo- 

 Jhyoideus and digastricus muscles, and twigs to the submaxillary 

 glands. 



The dental branches are given off in the dental canal, to 

 supply the teeth of the lower jaw ; one series supplying the 

 Tnolars,- the other the front teeth. 



The mental or terminal branches of the nerve, issuing from 

 the mental foramen, are distributed to the lower lip, and com- 

 XQunicate ydth the facial nerve. 



-The eympathetic ganglia, communicating with the fifth pair, 

 ^are the ophthalmic or lenticular, the spheno-palatine or Meckel's, 

 -aiKi the otic. (See Sympathetic 83rstem.)
