Your spine is made of many bones called vertebrae, and your spinal cord runs through a canal in the center of these bones. Since damaged neurons (nerve cells) in the spinal cord are not capable of regeneration, only spared neural pathways can be adapted and rewired through a process called neuroplasticity. While injuries to the L4 vertebra tend to be less severe than injuries to the spinal cord proper, symptoms include an inability to bend the feet in a particular direction.
