Internal (Enlarged.) part of this surface is a deep groove, the pterygopalatine groove, converted into a canal, the posterior palatine canal, by its articulation with the maxilla. It transmits the posterior or descending pala- tine vessels and the great or anterior palatine nerve from Meckel's ganglion. Borders. ?— The anterior border (Fig. 79) is thin, irreg- ular, and presents opposite the inferior turbinated crest a pointed, projecting lamina, the maxillary process (processiis maxillaris), which is directed forward, and closes in the lower and back part of the opening of the antrum. The posterior border (Fig. 80) presents a deep groove, the edges of which are serrated for articulation with the pterygoid process of the sphenoid. At the lower part of this border is seen a pyramidal process of bone, the tuberosity of the palate {processus pyramidalis), which is received into the angular interval between the two pterygoid plates of the sphenoid at their inferior extremity. This process presents at its back part a median groove and two lateral surfaces. The groove is smooth, and forms part of the pterygoid fossa, affording attachment to the Internal pterygoid muscle; while the lateral surfaces are rough and uneven, for articulation with the anterior border of each pterygoid plat
