Which statement concerning action potentials is false?
A) The magnitude of an action potential along an axon is the same, regardless of where it is measured.
B) Action potentials travel more quickly in large-diameter axons than in small-diameter axons.
C) Action potentials are conducted without loss of signal.
D) Whereas invertebrates rely on myelination of axons to increase conduction velocity, vertebrates rely on increased axon diameter.
E) Action potentials travel more quickly in myelinated axons than in nonmyelinated axons.
