Which of the following describes the dorsal cavity?

The dorsal cavity is an anatomical space that is essential for protecting and housing critical structures of the central nervous system. It is divided into two main areas: the cranial cavity, which encases the brain, and the spinal cavity (or vertebral canal), which contains the spinal cord. This arrangement is vital for safeguarding these organs from trauma and offers a supportive environment that allows for their proper function.

The heart and lungs, associated with the thoracic cavity, are not part of the dorsal cavity, removing that answer from consideration. Similarly, digestive organs are found within the abdominal cavity, not the dorsal cavity, and reproductive organs are primarily located in the pelvic cavity. Therefore, understanding the specific components of the dorsal cavity highlights the importance of its protective role for the central nervous system.
