Hence, an action potential travels down the axon of a neuron because neurotransmitters bind to receptors on the dendrite of the neuron. Recordings from squid synapses and neuromuscular junctions of the frog reveal a delay of 0.5 to 4.0 milliseconds between the onset of action potential at the nerve terminal and action potential at the postsynaptic site. In this article we will discuss how an action potential is generated and how conduction of an action potential occurs.
