Spinal Cavity refers to which?

• A. Space in the body that contains the spinal cord
• B. Space in the body that contains the heart
• C. Space in the body that contains the lungs
• D. Space in the body that contains the brain

Answer: (A)

The spinal cavity is the space inside the vertebral column that houses the spinal cord and its surrounding protective membranes. It’s part of the dorsal body cavity, which also includes the cranial cavity that contains the brain. The spinal cord runs through this vertebral canal from the base of the skull down to the lower spine, protected by the meninges and cerebrospinal fluid. The heart is located in the thoracic portion of the ventral body cavity, the lungs occupy the thoracic cavity, and the brain sits in the cranial cavity, not the spinal cavity. So the space that contains the spinal cord is the spinal cavity.
