  • (I) The action potential arrives at the end of the pre-synaptic neuron.
    (II)Calcium channels open and diffuse into the neuron down a concentration gradient.
    (III)Calcium ions trigger the vesicles.
    (IIII)The neurotransmitters within the vesicles diffuse across the synaptic gap.
  • (IV)The neurotransmitters bind to the post-synaptic cells membrane receptor sites on its sodium channels.
    (IIV)The neurotransmitters open the sodium channels causing sodium ions to pass in causing the depolarisation of the post synaptic membrane. Causing an action potential to be generated.
