<span>The paralysis is from a chain reaction of cells not processing sodium properly. This leads to their residing in a resting potential instead of forming action potentials, as is required for them to fire during muscle movements. The electrical impulses are not moving down the cells, leading to their not being able to move and, therefore, paralysis of the affected or poisoned areas.</span>
