Which statement about the spinal cord is correct?

Which statement about the spinal cord is correct?

• A. Limiting spine movement to prevent worsening injury
• B. Nerve bundle inside vertebral canal
• C. Holding head/neck in neutral alignment when possible
• D. Tailbone

Answer: (B)

The spinal cord is a bundle of nerve tissue housed within the vertebral canal, a protected tunnel formed by the vertebrae. Inside this canal, the cord carries signals between the brain and the rest of the body, with nerve roots exiting at each level to innervate muscles and convey sensation. That makes the description “nerve bundle inside vertebral canal” the accurate one. The other options describe management actions or unrelated anatomy (the tailbone is the coccyx), which aren’t direct descriptions of the spinal cord itself.
