The portion of the skull that encloses the brain is the?

• A. Mandible
• B. Parietal bone
• C. Frontal bone
• D. Cranium

Answer: (D)

The brain is protected by the part of the skull called the cranium. The cranium, or neurocranium, forms the protective bony box around the brain and includes the major skull bones that build the cranial vault. Individual bones like the frontal or parietal bones are parts of this enclosure, but they aren’t the whole structure themselves. The mandible, in contrast, is the lower jaw and belongs to the facial skeleton, not the brain’s enclosure. So the term for the portion of the skull that encloses the brain is the cranium.
