In MS, the immune system attacks and breaks down the myelin sheath surrounding CNS axons. What could be a consequence of this?
A) Conduction along the axon would be disrupted, interfering with the function of the neuron.
B) Conduction would be faster along the neuron without the myelin.
C) The neuron would not be able to generate a new action potential.
D) There would be no consequence, as myelin is not important to the function of the neuron.
