Which Statement is NOT True About the Action Potential of the Neuron

Question

Which statement is NOT true about the action potential of the neuron?
A)Repolarization occurs as movement of potassium ions occurs across the cell membrane
B)The action potential moves more slowly along a myelinated neuron than along one with no myelin sheath
C)The action potential travels the length of the axon in a self-propagating fashion
D)Saltatory conduction occurs from one node of Ranvier to another along a myelinated neuron
E)Large fibers in neurons of some invertebrates carry very rapid nerve action potentials

Accepted Answer

The statement that the action potential moves more slowly along a myelinated neuron than along one with no myelin sheath is incorrect. Myelin sheaths actually increase the speed of the action potential along the axon, a process known as saltatory conduction.
