Which part houses the spinal cord?

• A. Body
• B. Spinal Foramen
• C. Vertebral Arch
• D. Facet Joints

Answer: (B)

The spinal cord sits inside the vertebral canal, which is formed by the vertebral foramina stacked along the spine. The opening through which the cord passes is the spinal foramen (also called the vertebral foramen). This opening, together with the arches above and below, creates the canal that houses and protects the cord. The body is the front, weight-bearing part, while the vertebral arch forms the back boundary; facet joints are simple joints between vertebrae that allow movement and do not house the cord.
