MOVEMENTS OF THE PALATE AND TJTTTLA. 159 



induced by galvanization of the peripheral end of the nerve. 1 

 Section of the facial after its passage out of the stylo-mastoid 

 foramen did not arrest the action of the parotid ; but section 

 of the nerve within the cranium arrested the secretion, both 

 of the parotid and submaxillary. 9 



These observations show conclusively that the facial, 

 either through branches from its proper roots or its fila- 

 ments of communication with other nerves, regulates the 

 secretion of at least two of the salivary glands ; a fact to 

 which we have already alluded in another volume. 3 



Influence of Various Branches of the Facial upon the 

 Movements of the Palate and Uvula. There can be little 

 doubt that filaments from the facial animate certain of the 

 movements of the velum palati and uvula. It has been ob- 

 served that, in certain cases of facial paralysis, the palate 

 upon one side is perfectly flaccid and the uvula is drawn to 

 the opposite side. Montault * cites a case of this kind, and 

 a very striking example is given in full by Bernard ; 6 but 

 these phenomena do not occur unless the nerve be affected 

 at its root or within the aquseductus Fallopii. It is true 

 that the uvula is frequently drawn to one -side or the other 

 in persons unaffected with facial paralysis, as was observed 

 by Debrou, 6 but it is none the less certain that it is deviated 

 as a consequence of paralysis of the facial in some instances.' 

 These facts, however, in the absence of direct experiments, 

 do not show conclusively that the facial supplies the muscles 

 of the seft palate.
