Which term describes the cavity located in the cranial region that houses the brain?

• A. Cranial
• B. Dorsal Cavity
• C. Frontal Plane
• D. Medial

Answer: (A)

The space inside the skull that holds the brain is the cranial cavity. This term is used to describe anything related to the skull, so calling the cavity within the skull the cranial cavity fits perfectly. The dorsal cavity is the larger body-wide space that includes both the cranial and spinal cavities, so it’s not the specific term for the brain’s housing. The frontal plane is a dividing surface, not a cavity, and medial describes a location toward the midline, not a space. Therefore, cranial best names the cavity in the cranial region that contains the brain.
