Palatine bones

Conchal crest

A subhorizontally oriented crest placed not quite halfway up the perpendicular plate on the medial surface of the plate

Perpendicular/vertical plate

Appressed tightly to the posteromedial wall of the maxially opposite the maxillart sinus, between the pterygoid plates of the sphenoid and the posterior margin of the alveolar process of the maxilla

Horizontal plate

Forms the posterior third of the hard palate

Lesser palatine foramen

Located on the posterolateral corner of the hard palate posterior to the greater palatine foramina, near the junction of the perpendicular and horizontal plates

Greater palatine foramen

Perforates the rear corner of the hard palate and is formed as the alveolar process of the maxilla meets the horizontal plate of the palatine
