The myelin on myelinated neurons can be degraded or destroyed in diseases such as multiple sclerosis-a process called demyelination. if a myelinated neuron was affected by demyelination, how would this affect action potentials in that neuron?
a. action potentials would propagate in both directions along the axon.
b. initial generation of action potentials would be more difficult.
c. the speed of action potential propagation would be faster.
d. the speed of action potential propagation would be slower.
