Which bone forms the cheek region and contributes to the zygomatic arch?

• A. Frontal bone
• B. Nasal bone
• C. Lacrimal bone
• D. Zygomatic bone

Answer: (D)

The cheek region is formed by the zygomatic bone. It has a temporal process that joins with the temporal bone’s zygomatic process to form the zygomatic arch, the bony curve you can feel along the side of the face. The zygomatic bone also contributes to the orbit, helping shape the lateral wall and part of the floor. The other bones listed don’t form the cheek: the frontal bone makes the forehead and upper orbit, the nasal bone forms the bridge of the nose, and the lacrimal bone sits in the medial wall of the orbit. So the zygomatic bone is the one responsible for the cheek and part of the zygomatic arch.
