<P> Nodes of Ranvier , also known as myelin - sheath gaps , occur along a myelinated axon where the axolemma is exposed to the extracellular space . Nodes of Ranvier are uninsulated and highly enriched in ion channels , allowing them to participate in the exchange of ions required to regenerate the action potential . Nerve conduction in myelinated axons is referred to as saltatory conduction ( from the Latin saltare `` to hop or to leap '' ) due to the manner in which the action potential seems to `` jump '' from one node to the next along the axon . This results in faster conduction of the action potential . </P>
