64
Q

Diamond shaped bones that form the cheekbones. They are located on the frontal and lateral planes of the face. The bones form part of the inferior and lateral surfaces of the orbital cavity; has a convex surface (because it moves in the anterior & posterior direction.)

A

Temporal process of the zygomatic. When the arch is completely fused, it has three parts from anterior to posterior.

A

Palatine Process

95
Q

Anatomical features and RA significance
maxilla
oblique insertion of the teeth; can occur in the maxilla. The point where the two maxilla meet form a sharp bony process known as the nasal spine. The nasal spine creates the inferior border of the nasal skeleton.
