TRIFACIAL NERVE 



525 

 It also sends 



temporo-maxillary articulation and the parotid gland, 

 branches of communication to the facial. 



2. The lingual branch is distributed to the mucous membrane of the 

 tongue as far as the point, the mucous membrane of the mouth, the 

 gums and the sublingual gland. This nerve receives a branch from 

 the facial (the chorda tympani) which has already been described. From

I, branch from the motor root to the masseter muscle; 2, filaments from this branch to the tem- 

 poral muscle ; 3, buccal branch ; 5, 6, 7, branches to the muscles ; 8, auricula-temporal nerve ; 

 9, temporal branches ; 10, auricular branches ; II, anastomosis with the facial nerve ; 12, lingual 

 branch; 13, branch of the motor root to the mylo-hyoid muscle ; 14, 15, 15, inferior dental nerve, with 

 its branches ; 16, mental branch ; 17, anastomosis of this branch with the facial nerve. 



this nerve, also, are given off two or three branches that pass to the 

 submaxillary ganglion. 



3. The inferior dental nerve, the largest of the three, passes in the 

 substance of the inferior maxillary bone, beneath the teeth, to the men- 

 tal foramen, where it emerges upon the face. The most important sen- 

 sory branches are those which supply the pulps of the teeth and the 

 branches upon the face. The nerve emerging on the face by the men- 

 tal foramen, called the mental nerve, supplies the integument of the chin,
