what is saltatory conduction?
a type of action potential propagation that occurs in the dendrites of neurons
a type of action potential propagation that occurs in myelinated axons where the signal jumps from node to node
a type of action potential propagation that occurs in myelinated axons where the signal travels smoothly along the axon
a type of action potential propagation that occurs in the synapses between neurons
a type of action potential propagation that occurs in unmyelinated axons where the signal jumps from node to node

Explanation:

Saltatory conduction is a process in which action - potential propagates in myelinated axons. Myelin sheaths insulate the axon, and the signal jumps from one node of Ranvier (uninsulated regions) to the next, speeding up the signal transmission.

Answer:

A type of action potential propagation that occurs in myelinated axons where the signal jumps from node to node
