What is the term for the portion of the skull that encloses the brain?

• A. Cranium
• B. Mandible
• C. Maxillae
• D. Nasal

Answer: (A)

The cranium is the portion of the skull that encloses the brain. It forms a protective case around the brain with several bones fused together, allowing for a rigid shield against injury. In contrast, the mandible is the lower jaw that moves to chew and speak, the maxillae are the upper jaw bones that support the teeth and help shape the midface, and the nasal bones form the bridge of the nose. So, the term that best describes the part of the skull surrounding and protecting the brain is the cranium, because its primary role is brain protection, not chewing, tooth support, or nasal structure.
