The dorsal body cavity encompasses the cranial cavity and the spinal column. This cavity is primarily located at the back of the body and protects the central nervous system, which includes the brain housed in the cranial cavity and the spinal cord contained within the vertebral column. Understanding this is crucial as it helps in identifying areas where injuries or diseases can affect neurological functions.

The cranial cavity protects the brain, while the spinal cavity protects the spinal cord, both of which are vital components of the central nervous system. This anatomical distinction is important for healthcare professionals, as conditions affecting the brain or spinal cord can have significant implications for patient care and treatment strategies.
