Which subdivision encases the brain?

Explanation:
Think about how the brain is housed inside a protective bony chamber. The space inside the skull is called the cranial cavity, a subdivision of the dorsal body cavity. The dorsal cavity also includes the vertebral (spinal) cavity, which surrounds the spinal cord, not the brain. So while the dorsal cavity covers both brain and spinal cord, the specific compartment that encases the brain is the cranial cavity.
