      Serotonin
    • Which neurotransmitter is associated with relaxation?

    • What are synapses?
      Small gaps between neurons
    • How is an electrical impulse triggered in a neuron?
      It is triggered inside the neuron's cell body
    • What happens to the electrical impulse after it is triggered in the neuron's cell body?
      It is passed along the axon towards the end of the nerve fiber
    • What is contained in the terminal button of a neuron?
      Vesicles filled with neurotransmitters
