In the case of a spinal cord injury, signals coming from the nerves and the signals coming to the receptors will be disrupted. This is because both these signals meet in a bundle in the spinal cord. Hence, both these signals get disrupted.
When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they cannot go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled. They may happen when the foot is touched or with coughing.
