10. Palatine and Nasal Bones • Palatine bones • Small “L” shaped bones • Form the posterior hard palate and floor of the nasal cavity • Nasal bones • Superior border of external nares

11. Vomer, Zygomatic and Lacrimal bones • Vomer • Inferior portion of the nasal septum • Zygomatic bone • Temporal process articulates with zygomatic process of temporal bone • Lacrimal bones • Smallest bones of the face • Sit medially in orbit
