Which cavity is in the skull and encases the brain?

• A. Vertebral Cavity
• B. Dorsal Cavity
• C. Cranial Cavity
• D. Cranial Cavity (encases the brain)

Answer: (D)

The brain lives in a specific space inside the skull called the cranial cavity. This cavity is part of the dorsal body cavity, which also includes the vertebral cavity for the spinal cord. The brain’s enclosure is what the cranial cavity provides—the bones of the skull form a protective, bony chamber around it. The option that names the cranial cavity and notes that it encases the brain best captures both its location (in the skull) and its function (enclosing the brain). The vertebral cavity houses the spinal cord, and the dorsal cavity is the larger region that includes both cranial and vertebral spaces.
