Passage of an action potential along an myelinated axon (2)

- Localised circuits arise between adjacent nodes of Ranvier - APs in effect jump from node to node in a process called saltatory conduction - So, AP passes along a myelinated neuron faster than unmye. axon of same diameter - Coz in unmyel. neuron, depolarisation have to take place all the way along axon, so takes time
