Question

Quizplus · Accepted Answer

Continuous conduction of a nerve impulse occurs only along unmyelinated axons. Action potentials travel down the entire length of the unmyelinated axon, one segment at a time, in a continuous manner. In myelinated axons, action potentials can only occur at nodes of Ranvier, where the axon is not covered in myelin.
