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 fossa|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. === Articulations === The palatine articulates with six bones: the [[sphenoid]], [[ethmoid]], [[maxilla]], [[inferior nasal concha]], [[vomer]] and opposite palatine. ==Additional images== <gallery> Image:Orbital_bones.png|The seven bones which articulate to form the orbit.
