Nerve impulses are extremely slow compared to the speed of electricity, where the electric field can propagate with a speed on the order of 50–99% of the speed of light; however, it is very fast compared to the speed of blood flow, with some myelinated neurons conducting at speeds up to 120 m/s

How fast do the fastest nerve impulses travel?

The fastest nerve impulses travel at 288 km/h (180 mph) and are achieved by various nerves in the body.

How fast can neurons send signals *?

A highly myelinated nerve cell can send a signal at up to 120 meters per second, or nearly 270 miles per hour, quite a bit faster than an airplane taking off! These quick speeds are the basis for everything the nervous system does, from making sense of what your eyes see to deciding what you’re going to have for lunch.
