Which cavity runs within the vertebral column and encloses the spinal cord?

• A. Vertebral Cavity (Spinal Cavity)
• B. Cranial Cavity
• C. Dorsal Cavity
• D. Thoracic Cavity

Answer: (A)

The structure that runs inside the vertebral column and encloses the spinal cord is the vertebral (spinal) cavity. This hollow space is formed by the vertebral foramina stacked along the spine, creating the vertebral canal that protects the spinal cord and the surrounding meninges. It’s a subset of the dorsal body cavity, which also includes the cranial cavity that houses the brain. The thoracic cavity, in contrast, is part of the ventral body cavity and contains structures like the heart and lungs. So the specific cavity within the vertebral column that encloses the spinal cord is the vertebral (spinal) cavity.
