What is the role of neurotransmitters in the nervous system? (2019)
  • Step 1: Understand that the nervous system is made up of cells called neurons.
  • Step 2: Know that neurons communicate with each other to send signals.
  • Step 3: Learn that neurotransmitters are special chemicals that help in this communication.
  • Step 4: Recognize that when a neuron wants to send a signal, it releases neurotransmitters.
  • Step 5: Understand that these neurotransmitters travel across a small gap called a synapse.
  • Step 6: Realize that the neurotransmitters attach to the next neuron, allowing the signal to continue.
