Oral Anatomy

The horizontal ledge extending medially from the nasal surface of the maxilla is the	Palaltine process
Foramina of Stenson carries	Nasopalatine nerves
Foramina of Scarpi  carries	Descending septal artery
The facial plate of maxillary alveolar process is	Thin. But the buccal plates of second and third molars are thick
The maxillary alveolus that is kidney shaped with the hilus part in its mesial surface is the	First premolar. In the second premolar, the hilus is in distal surface. The reason for the kidney shaped is due to the developmental grooves in the teeth and subsequently occupied by the alveolar bone.
Medially maxilla articulates with	Inferior turbinate; Vomer; Opposite maxilla
In the lower border of mandible, proximal to symphysis are two prominences called	Mental tubercles
The triangular surface formed by the symphysis and mental tubercles is the	Mental protrubence
The condylar and coronoid process is separated by the	Sigmoid notch
The concave pit medially below the neck of condyle is the	Pterygoid fossa
