The viscerocranium forms which portion of the skull?

• A. The Cranial Vault
• B. The Cranial Base
• C. The Auditory Region
• D. The Facial Skeleton

Answer: (D)

Viscerocranium is the facial skeleton. It forms the front part of the skull—the bones that shape the face and support the openings for the eyes, nose, and mouth. These include the maxillae, zygomatic bones, nasal bones, lacrimal bones, palatine bones, vomer, inferior nasal conchae, and the mandible. In contrast, the cranial vault and cranial base are part of the neurocranium and protect the brain, with the auditory region housed in the temporal bone within that neurocranium. Therefore, the viscerocranium constitutes the facial skeleton.
