The Palatine Bones are paired left and right and articulate with one another in the mid-sagittal plane at the Interpalatine Suture.

Each bone possesses a Horizontal Part, with an inferior surface which forms the posterior portion of the hard palate and a superior surface that assists in forming the posterior portion of the floor of the nasal cavity.
