Distinguish cranial and facial bones

Using the Skull Bone Classification knowledge point

The skull is divided into two main categories of bones:

• Cranial bones: These bones enclose and protect the brain. The eight cranial bones are the frontal, parietal (2), temporal (2), occipital, sphenoid, and ethmoid bones.
• Facial bones: These bones form the structure of the face. Examples include the maxilla, mandible, zygomatic, nasal, lacrimal, palatine, inferior nasal conchae, and vomer.

Evaluate the given options

• Maxilla: This is a facial bone that forms the upper jaw, not a cranial bone.
• Occipital: This is a cranial bone located at the back and base of the skull.
• Parietal: These are cranial bones forming the sides and roof of the cranium.
• Frontal: This is a cranial bone forming the forehead.
