Nerve cells

Post by Ilyaas » Sat Dec 10, 2005 10:31 pm

Can anyone explain why neurones within the CNS cannot repair themselves whereas neurones in the PNS can? Is there yet a cure or a process found by which damaged nerves can be replaced?

I don't fully know this answer, and I don't know if all of it has been discovered.

I can give you this:

The only thing that comes to my mind is that in the 9 stages of regeneration the Schwann cells have a key role, by enetering mitosis and generating the Fillipodi growth cone. Also, take notice that a neuron can only regenerate if the lesion took place in the axon and not the cell body, and since the CNS is mostly made out of cell bodies...
