Action potentials travel along the axons of neurons.
... A nerve is usually composed of a bundle of neurons with Glial cells and blood vessel to supply needed materials. Neurons are not connected directly to one another – there are gaps (synapses) between the neurons. Action potentials travel along the axons of neurons. ...
