portion at the inner end is rounded and faintly emarginate and forms 

 the posterior boundary of the anterior palatine foramen. 



The inner border is serrated through its entire length. In its 

 first third it is directed slightly inward as well as backward, and 

 articulates with the outer part of the posterior end of the palatine 

 process of the prernaxillary. In the rest of its course it is longitudinal 

 and joins its fellow. It forms, behind, a right angle with the posterior 

 border. 



The posterior border passes at first, for a short distance, directly 

 outward. It then turns sharply and runs backward and outward to 

 become the posterior part of the inner border of the lower surface of 

 the body of the bone. It articulates with the horizontal plate of the 

 palatine bone. 



The lower surface of the palatine plate of the maxillary (Fig. 

 267) is nearly smooth, and slightly elevated in a longitudinal line near 

 the inner border. Near, and in, its posterior border, at about the 

 middle, are a notch and groove for the posterior palatine canal. This 

 surface is covered by the mucous membrane of the mouth. 



The upper surface of this process (Figs. 268, 269) has the same 

 general form as the under surface, narrow in front and wide behind.
