*The neurotransmitter is taken up by the presynaptic neuron
*Neurotransmitters bind to receptors on the post synaptic membrane
*Calcium enters the cell
*An action potential arrives at the presynaptic knob.
*The mebrane is either excited or inhibited.
*Synaptic vesicles fuse with the membrane of the transmitting cell.
