In all spinal cord injuries at least part of the spinal cord is damaged. Unlike other organs in your body, the spinal cord does not have the ability to heal. Once an injury has occurred, the injured cells in the spinal cord die and they will never heal. As of now, there is no cure for a spinal cord injury.
Information that was normally relayed through the spinal cord is interrupted
following an injury. Depending on how much of the spinal cord is injured, and
what specific tracts are injured, some information will not be able to get to
and from the brain. If the entire width of the spinal cord is injured, anywhere
along it's length, no information will be able to get above or below the injury.
This causes people to have no sensation and no ability to move large portions
of their bodies.
