Peripheral Nerve Regeneration

Peripheral nerve regeneration is the body's natural process of repairing damaged nerves outside the brain and spinal cord. When a peripheral nerve is injured, the process begins with the nerve fibers clearing out debris and forming a pathway. Supportive cells called Schwann cells assist in guiding new nerve fibers to reconnect with their original targets, such as muscles or skin. Over time, the nerve fibers regrow, restoring function and sensation. The speed and success of recovery depend on the injury's severity and location, but generally, peripheral nerves have a remarkable ability to heal and regenerate compared to central nervous system nerves.
