View Explanation

An axon can conduct in either direction. When an action potential is initiated in the middle of it, two impulses traveling in opposite directions are set p by electrotonic depolarization on either side of the initial current sink. In the natural situation, impulses pass in one direction only, ie, from synaptic junctions or receptors along axonsto their termination. Such conduction is called orthodromic. Conduction in the opposite direction is called antidromic. Because synapses, unlike axons, permit conduction in one direction only, an antidromic impulse will fail to pass the first synapsethey encounter and die out at that point.
