THE CRANIAL OE ENCEPHALIC NERVES.

auriculo-temporal branch that ascends in front of the ear, and terminates in the skin of 

 the temporal region. 



In Man, there is annexed to the fifth pair the submaxillary ganglion, which receives 

 a sensitive branch from the lingual, a motor filament from the chorda tympani, and 

 sympathetic filaments ; it gives off several emergent filaments, nearly all of which pass 

 into the maxillary gland. There is nothing to say of the internal motores oculorum. 



Facial. In its collateral branches, the facial nerve of Man is absolutely the same as 

 in animals. It has, however, a branch not described in them the ramuscule of 



Fig. 344.

Hirschfeld, which reaches the base of the tongue, where it is distributed by mixing 

 with the glosso-pharyngeal. The termination much resembles that of the Dog. Two 

 principal branches have been named the temporo-facial and the cervico-facial. The 

 first receives the superficial temporal nerve, and describes an arch from which are 

 detiched the temporal, frontal, palpebral, suborbital, and buccal ramuscules. which 

 form the subparotideal plexus. The second, lodged in the parotid, passes towards the 

 angle of the jaw, where it anastomoses with the cervical plexus ; it furnishes the inferior 

 buccal, mental, and cervical branches. 



Glosso-pharyngeal. This nerve commences and terminates as in Solipeds, and has the 

 same relations. It furnishes the branches of the digastric and stylo-hyoid muscles, the
