Detailed explanation-1: -Nerve impulses only travel in one direction in neurons. This impulse transmission is dependent on synaptic transmission. This happens because nerve cells only have one transmission site. The receptors also work in one direction.
Detailed explanation-2: -Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination-a web of communication that allows you to move, think, feel and communicate.
Detailed explanation-3: -A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport. In order for a “nerve impulse” to pass from cell to cell, it must cross synaptic junctions.
