why dont impulses travel in only on direction

Asked by  | 24th Mar, 2009, 04:45: PM

Expert Answer:

Neurons communicate or send impulses through an action potential. This takes place from the dendrite and all the way to the axon ends. An action potential is a change of voltage within the axon. In other words, the negative state off the inner axon turns positive when the impulses pass by. This happens by the use of a sodium and potassium pump.
