sensory fibers. It continues at the ventral medial border of the 

 Gasserian ganglion until the profundus ganglion is reached (fig. 

 24). From this point the ramus palatinus and the abducens 

 nerve, which has" become closely associated with it, run at the 

 medial ventral border of the latter ganglion. At about the level 

 where the ramus maxillaris V emerges ventrally from the mas- 

 seter and temporal muscles the ramus palatinus divides into

medial and lateral branches. The anastomoses of these branches 

 with the ramus maxillaris have been noticed in the section de- 

 scribing the latter nerve. 



In Ichthyophis the ramus palatinus passes at first directly 

 ventrally from the ganglion in a canal in the basal bone, then, 

 turning abruptly anteriorly, emerges from the canal and runs 

 anteriorly along the usual course.
