Answer #1

Neurons present in the peripheral nervous system regenerate while those neurons present in the central nervous system have less chance of regenerating because of the following reasons,

  • Environment surrounding CNS lesions are inhibitory to axon growth.
  • CNS neurons mount only a feeble regeneration response
  • Injury to brain cells leads to nerve cell death
  • Glial cells actively inhibit neuronal growth
  • Neural stem cells are constrained in their ability to migrate, divide and differentiate
