Nerve cells in the peripheral nervous system that are wrapped in neurilemma have the ability to repair themselves if damaged. This is because the neurilemma contains specialized cells called Schwann cells that can stimulate the growth of new axons, which allows the damaged nerve to regenerate. Nerve cells in the central nervous system (A and B) do not have neurilemma and therefore cannot repair themselves as easily. Nerve cells in the spinal cord (D) may have some limited ability to repair, but it is not as extensive as in peripheral nerves with neurilemma.
