It contributes to the walls of three cavities: the floor and lateral wall of the nasal cavity, the roof of the mouth, and the floor of the orbit; it enters into the formation of two fossæ, the pterygopalatine and pterygoid fossæ; and one fissure, the inferior orbital fissure.
The palatine bone somewhat resembles the letter L, and consists of a Horizontal plate of palatine bone and a Perpendicular plate of palatine bone and three outstanding processes—viz., the Pyramidal process of palatine bone, which is directed backward and lateralward from the junction of the two parts, and the Orbital process of palatine bone and Sphenoidal process of palatine bone, which surmount the vertical part, and are separated by a deep notch, the sphenopalatine notch.
