The vertebral column protects the spinal cord primarily through its structural design. Each vertebra consists of a ventral body, or centrum, and a dorsal neural arch. Together, these components surround an opening known as the vertebral foramen. When vertebrae are stacked, these successive openings form the spinal canal, which serves as a protective conduit for the spinal cord.12

Beyond this bony enclosure, the spinal cord receives additional protection from the meninges—the protective membranes covering the cord—and cerebrospinal fluid, which acts as a cushion against mechanical stress. While the vertebral column provides the primary rigid framework, these physiological adaptations work in concert to ensure the safety of the central nervous system.34
