These axons transmit signals to the target muscle in the form of electric impulses called action potentials. However, the axons alone are not enough to produce rapid conduction of the electric ...

Illustration of myelinated nerve fiber and saltatory conduction of action potential. An example of PNS myelinated nerve fiber is shown. (B) Illustration of transverse section of myelinated axon at ...

For more than 70 years, scientists have depicted axons as ultrathin cables, varying in diameter along their length but roughly cylindrical in shape. Electrical signals (action potentials ...
