Describe the processes which occur that allow synaptic transmission

  1. The action potential arrives at the axon terminal 2) Voltage-gated Ca2+ channels open 3) Ca2+ enters the presynaptic neurone 4) Ca2+ signals to neurotransmitter vesicles 5) Vesicles move to the membrane and release the neurotransmitter by exocytosis 6) Neurotransmitter binds to receptors 7) Signal initiated in post-synaptic cell
