The vertebral or spinal cavity houses which structure?

• A. Brain
• B. Spinal Cord
• C. Heart
• D. Lungs

Answer: (B)

The spinal cavity contains the spinal cord. This space runs inside the vertebral column and is protected by the vertebrae and protective membranes around the CNS. The brain sits in the nearby cranial cavity, not inside the spinal canal. The heart and lungs reside in the chest (the thoracic cavity), far from the vertebral column. So the structure contained within the vertebral/spinal cavity is the spinal cord, which acts as a major communication line between the brain and the rest of the body.
