WebJul 6, 2024 · Myelin speeds up impulses By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire length of the nerve fibre.Myelinated nerves can transmit a signal at speeds as high as 100 metres per second – as fast as a Formula One racing car. WebIn neuroscience, saltatory conduction (from Latin saltus 'leap, jump') is the propagation of action potentials along myelinated axons from one node of Ranvier to the next node, increasing the conduction velocity of action potentials. The uninsulated nodes of Ranvier are the only places along the axon where ions are exchanged across the axon membrane, …
