Almost immediately their arrangement becomes so complicated 

 that it cannot be easily described. This arrangement is, how- 

 ever, accurately represented in the graph (fig. 7, N.Sp.). A 

 greater part of five of the six bundles assist in forming the an- 

 terior palatine nerve and its posterior inferior nasal branch, and 

 the greater part of the other bundle assists in forming the naso- 

 palatine nerve. 



From these six bundles there are only two small subdivisions 

 that enter the sphenopalatine ganglion, joining it well toward its 

 anterior end and close to the point of origin from the ganglion 

 of the fibers which enter the nasopalatine nerve. In transverse 

 series these bundles can be followed through the ganglion into 

 the nasopalatine nerve, which is probably their fate in the other 

 series. 



c. Nervus palatinus anterior. The anterior palatine nerve is 

 the largest of the nerves in this region. The bundles from the 

 maxillary nerve which form it pass medially and anteriorly across 

 the ventral border of the sphenopalatine ganglion. While in 

 this position they are joined by four bundles whose fibers come 

 from the interior of the sphenopalatine ganglion. The fibers 

 from the ganglion are smaller than those from the maxillary 

 nerve and represent about one-third of the fibers of the anterior 

 palatine nerve. 



From the ventral border of the sphenopalatine ganglion the 

 anterior palatine nerve passes ventrally through a canal to reach 

 the mucous membrane of the palate. In this canal one bundle 

 separates from the nerve, and as soon as the mucosa is reached, 

 takes a posterior direction. The remainder of the nerve passes 

 anteriorly just lateral to the middle of the hard palate. 



The posterior inferior nasal branch of the anterior palatine 

 nerve is made up of two small bundles of fibers from the spheno- 

 palatine nerves (fig. 6, a, b) and four smaller bundles of fine fiber 

 from the sphenopalatine ganglion (fig. 7). This nerve extends 

 anteriorly along the lateral wall of the nasal cavit}^, the smaller 

 fibers soon leaving it to enter a mass of glands in the lateral wall 

 of the nose (gland of Stenson). The fibers of larger size end 

 in the mucous membrane of the lateral wall of the nasal cavity.
