E) are unmyelinated.

Question

Quizplus · Accepted Answer

Schwann cells play a crucial role in the regeneration of PNS neurons by providing stimulation and guidance to axons. They produce growth factors and form cellular pathways that help guide the regenerating axons back to their target tissues. Without Schwann cells, PNS axons are less able to regenerate effectively.
