NERVUS FACIALIS OF ALBINO MOUSE

in the bone and extends to the mucous membrane of the palate. 

 In some series it was possible to follow a minute bundle from the 

 sphenopalatine ganglion into it ; in other series this could not be 

 done. When present this bundle is even smaller than the ones 

 joining the posterior palatine. 



The termination of these nerves will be discussed later.

b. Nervi sphenopalatini. The sphenopalatine nerves take 

 origin from the ventromedial part of the maxillary nerve at 

 about the middle of the sphenopalatine gangUon (fig. 5, bundles 

 a, h, c, d, e, g, i, and part of/.). The bundles of fibers present 

 in these nerves vary in different series. In the one represented 

 in the graph, figure 7, and from which figures 4, 5, and 6 were 

 drawn, there were six distinct hurdles at their point of origin.
