THE NERVOUS SYSTEM – RESEARCH TOPICS

The following questions will require you to conduct your own research. Choose any that interest you. Write your answers in your notebook, or create a poster or presentation.

Topic 1

Neurons can be classified based on their structure into the following three types:

  • Multipolar neurons
  • Bipolar neurons
  • Unipolar neurons

Compare the structure of these different types of neurons and draw labelled diagrams representing each. Give examples of where each type of neuron can be found in the body.

Topic 2

Neurotransmitters can be classified into the following three types:

  • Excitatory neurotransmitters
  • Inhibitory neurotransmitters
  • Modulatory neurotransmitters

Compare the function of each class of neurotransmitter and give examples of each.
