Neurotransmitters are those chemical messages that transmits signals from nerve cells to their target cells.

Neurotransmitters are packed inside vesicles at the presynaptic nerve terminal.

The arrival of an action potential at this terminal leads to opening of Voltage gated channels.

This leads to a change in membrane voltage of the postsynaptic cell following the influx of positively charged ions (sodium ion) into the cell which is called the excitatory postsynaptic potential.
