Axons typically conduct signals between a wide range of speeds: 0.5 to 100 m/s.1  The DRG is the longest axon in the human body.ote that for the sensations in the toes, this means that the axon goes all the way from the toe to the medulla, which is at about the same height as the mouth. This can be more than 2 meters long in tall people. That's a long axon!
