Which axons will regenerate to a significant degree if cut or crushed?

Axons in the peripheral nervous system have the capacity to regenerate to a certain extent, while those in the central nervous system do not have this ability. Myelination is not a significant factor in axon regeneration. Invertebrates may have a greater capacity for axon regeneration than vertebrates, but this is not as significant as the difference between regeneration in the peripheral versus central nervous system.
