Action potential conduction by unmyelinated axons. Introduction: Axons transmit the action potential from the axon hillock to the end of the axon till it reaches the dendrites of another neuron. Unmyelinated axons do not have a myelin sheath covering them and the process of depolarization and repolarization occurs across the entire axon membrane. The action potential is conducted due to the cable properties of the axon which can conduct charges.
