Multiple Choice: Chapter 6 Conduction of action potentials

Question 6.1Which of the following is true about the conduction of action potentials?

A thicker axons conduct action potentials faster because there is a faster current flow in thicker axons
B action potentials travel faster in unmyelinated nerve fibres than myelinated nerve fibres
C the action potential in myelinated axons is generated only at the nodes of Ranvier
D the action potential in an unmyelinated nerve has an amplitude that declines with distance from its site of origin
