Final answer:
The lateral projection of the face is used to image the zygomatic arch bone.
Step-by-step explanation:
The lateral projection of the face, known as a lateral view of the skull, is used to image the zygomatic arch bone. The zygomatic arch is formed by the junction of two bony processes: the short anterior component, the temporal process of the zygomatic bone (cheekbone), and the longer posterior portion, the zygomatic process of the temporal bone. It spans from the area of the cheek to just above the ear canal and separates the large rounded brain case from the upper and lower jaws.
