A 48-year-old male has a new diagnosis of Guillain-Barré syndrome. Which of the following processes underlies the deficits that accompany the degeneration of myelin in his peripheral nervous system (PNS)? (Points : 0.4)
The destruction of myelin causes fewer Schwann cells to be produced in the patient’s PNS.
The axonal transport system is compromised by the lack of myelin surrounding nerve cells.
Nerve cells lack insulation and impulse conduction is compromised by the destruction of myelin.
A deficit of myelin predisposes the patient to infection by potential pathogens.
