Multiple Choice

Which statement about axons is false?

A) Invertebrates rely on increasing axon diameter to increase conduction speed.
B) In vertebrates, myelination of axons is one way to increase conduction speed.
C) When an axon is myelinated, action potentials can only be fired at the nodes.
D) Voltage-gated ion channels are clustered at the nodes of myelinated axons.
E) Saltatory conduction is fast because ion channels open and close faster than electric current can flow through the cytoplasm.
