So this electric current is the electric signal. So eventually the electric signal reaches the synaptic bouton or our axon terminal. So the electric signal passes along the axon. Eventually it reaches these bulb like structures that we discussed earlier. Now this will usually stimulate our bulb like structure to release vesicles that carry neurotransmitters into this region. And then these neurotransmitters will bind to postsynaptic cell receptors, also known as effective cell receptors, on the cell membrane of this postsynaptic cell.
