MOVEMENTS OF THE PALATE AND UVULA. 161 



geal nerve was then galvanized upon the side on which the 

 fhcial had been divided, with the effect of producing move- 

 ments of the pillars of the fauces, but not of the velum palati 

 itself. The glosso-pharyngeal was then galvanized upon the 

 side on which the facial was intact, which produced move- 

 ments of the velum the same as in the first experiment. 

 Galvanization of the pneumogastric, the sublingual, and the 

 lingual branch of the fifth, failed to produce movements of 

 the velum. 



" The first experiment proves that the glosso-pharyngeal 

 nerve is not the motor nerve of the velum palati, but that it 

 induces reflex movements by the excitation which it trans- 

 mits to the nervous centre, an excitation which is carried to 

 the parts by another nerve. 



"The second experiment proves that the reflex move- 

 ments of the velum palati, induced by the excitation of the 

 glosso-pharyngeal,- are in part transmitted by the facial 

 nerve, the movements of the pillars not being produced by 

 filaments belonging to this nerve." J 



Bernard also noted a fact, which has sometimes been 

 observed in cases of facial paralysis, that the point of the 

 tongue is deviated after section of the facial ; which is ex- 

 plained by the presence of a filament described by Hirsch- 

 feld, going from the facial to the tongue. 



As we before remarked, the experiments of Bernard do 

 not indicate the mode of communication between the facial 

 and the muscles of the palate. Longet regards the filaments 

 of the facial which influence the levator palati and azygos 

 uvulse muscles as derived from the large petrosal branch 

 of the nerve, passing to the muscles through MeckeFs gan- 

 glion, the filaments to the palato-glossus and the palato- 

 pharyngeus being given off from the glosso-pharyngeal, but 

 originally coming from an anastomosing branch of the facial. 

 As regards the branches of communication from the glosso-
