Palatines

perpindicular plate

appressed tightly to the posteromedial wall of the maxilla... opposite to the maxillary sinus, between pterygoid plates of the sphenoid and posterior margin of the alveolar process of the maxilla

pterygopalatine canal

becomes visible (sweeps posterosuperiorly) when the maxilla and perpindicular plate of the palatine are disarticulated

horizontal plate of palatine bone

forms posterior third of the hard palate

posterior nasal spine

located on the superior surface of the horizontal plate

pyramidal process of palatine

posterior border of the perpendicular plate is the thickets border... bears a serrated groove that articulates with the medial pterygoid plate of the sphenoid

Lesser palatine foramina

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

conchal crest

subhorizontally oriented crest placed not quite halfway up the perpendicular plate on the medial surface of the plate... for articulation with the inferior nasal concha

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 palatine... transmits greater palatine vessels and nerve
