Final answer:
A damaged neuron has a better chance of survival and repair if the Schwann cells are undamaged. Schwann cells produce the myelin sheath that insulates axons in the peripheral nervous system.
Step-by-step explanation:
A damaged neuron has a better chance of survival and repair if the Schwann cells are undamaged.
Schwann cells are a type of glial cell that produce the myelin sheath, which insulates the axons in the peripheral nervous system. The myelin sheath helps to protect the damaged neuron and allows for more efficient transmission of electrical signals.
