. Cunningham's Text-book of anatomy. Anatomy. 152 OSTEOLOGY. Sphenoid Sphenoidal process Pterygopalatine groove Middle meatus Orbital process Orbital surface. Crista conchalis Inferior meatus Nasal crest' Posterior nasal spine Horizontal plate For medial pterygoid lamina Fig. 161.—The Right Palate Bone. As seen from behind. where it articulates with the anterior part of the medial pterygoid lamina, expands below into the pyramidal process. The inferior border of the vertical part is con- fluent with the lateral edge of the horizontal part; posteriorly, and immediately in front of the tuberosity, it is notched by the lower extremity of the larger palatine foramen. The superior border supports the orbital and sphenoidal processes; the former — the anterior—is separated from the latter by a notch (incisura sphenopalatina), which is converted into the spheno-palatine fora- men by the articulation of the palate bone with the inferior surface of the sphenoid. Through this communication between the pterygo-palatine fossa and nasal cavity pass the spheno-palatine artery and the nasal branches of the spheno-palatine ganglion. The processus pyramidalis (pyra- midal process) is directed backwards and laterally from the angle formed by the perpendicular and horizontal parts, and presents, on its posterior surface, a central smooth vertical groove, bounded on either side by rough articular furrows which unite above in a V-shaped manner with the upper thin posterior edge. These latter articulate with the anterior parts of the lower portions of the medial and lateral ptery- goid laminae, while the central groove fits into the wedge - like interval between the two pterygoid laminse, thus entering into the formation of the pterygoid fossa. The lateral surface of the pyramidal process is*rough above, where it is confluent with the lateral surface of the perpendicular part which articulates with the tuberosity of the maxilla; below, there is a small, smooth, triangular area whic
