A spinal cord injury is damage to the spinal cord. It’s an extremely serious type of physical trauma that’s likely to have a lasting and significant impact on most aspects of daily life.The spinal cord is a bundle of nerves and other tissue that the vertebrae of the spine contains and protects. The vertebrae are the bones stacked on top of each other that make up the spine. The spine contains many nerves, and extends from the brain’s base down the back, ending close to the buttocks.The spinal cord is responsible for sending messages from the brain to all parts of the body. It also sends messages from the body to the brain. We’re able to perceive pain and move our limbs because of messages sent through the spinal cord.If the spinal cord sustains an injury, some or all of these impulses may not be able to “get through.” The result is a complete or total loss of sensation and mobility below the injury. A spinal cord injury closer to the neck will typically cause paralysis throughout a larger part of the body than one in the lower back area.
