Axonal Regeneration

Axonal regeneration refers to the process by which nerves, specifically their long projections called axons, repair themselves after injury. When a nerve is damaged, the body can sometimes guide the axon to grow back toward its target, restoring communication between the brain or spinal cord and the body. This process involves nerve cells activating growth programs, clearing debris, and creating a supportive environment for new growth. Although regeneration occurs effectively in the peripheral nervous system, it is more limited in the central nervous system. Successful regeneration can recover lost functions, but the extent depends on the injury and location.
