Which of these is not one of the facial bones?

A) frontal

B) maxilla

C) vomer

D) mandible

E) zygomatic

Answer: A) frontal

The frontal bone is mentioned as an element of the cranial bones, although it is commonly attached to the facial bones list. It forms the forehead and the upper eyelids as well as the front part of the eye orbits. The facial bones are those which form the face skeleton starting at the forehead down to the chin. Some of them are maxilla, vomer, mandible, zygomatic and etc. The frontal bone, even though it is involved in forming the face, is taken as a cranial bone since it is involved in the protection of the frontal lobe of the head and the shapes of the skull.
