The dorsal body cavity protects the fragile nervous system organs and has two subdivisions. Which are they?

• A. Cranial Cavity and Vertebral or Spinal Cavity
• B. Dorsal Cavity and Ventral Cavity
• C. Cranial Cavity and Thoracic Cavity
• D. Vertebral Cavity and Pelvic Cavity

Answer: (A)

The dorsal body cavity is the posterior space that protects the brain and spinal cord. It has two subdivisions: the cranial cavity, which houses the brain, and the vertebral (spinal) cavity, which surrounds the spinal cord. These two areas are the protective compartments of the nervous system within the dorsal cavity, separate from the ventral body cavities like the thoracic or pelvic cavities used for other organs.
