Schwann cells are a type of glial cell found in the nervous system. In addition to the conduction of nerve impulses, the outermost layer called neurilemma aids in nerve development and regeneration.

Which of the following explains why the neurons in the brain cannot repair damage like the neurons in your hands or feet can?


a.
Neurons in the central nervous system lack neurilemma of Schwann cells.


b.
Axons of the peripheral nervous system lack neurilemma of Schwann cells.


c.
Neurons in the central nervous system are surrounded by white matter.


d.
Neurons in the peripheral nervous system are surrounded by grey matter.


Never learned about Neurulemma in any of my course so its a bit confusing.

Hi Jesse

I believe I answered this exact same question years ago. See if my explanation then works for you now:
