Exercise

  1. Explain the purpose of the nervous system (detection of stimuli, coordination, and response).
  2. Ask participants to discuss the nervous system and how it is different, but necessary for other systems such as the endocrine system (control of bodily functions).
  3. Discuss the neuron as the basic unit of the nervous system, draw a representative neuron, and show representations of nerve cells. See http://www.merlot.org/merlot/viewMaterial.htm?id=482586
  4. Explain the mechanism of the neuron and how messages are transferred along a neuron. See http://www.merlot.org/merlot/viewMaterial.htm?id=482586
  5. Discuss functions of the spinal cord and brain and then show how these parts are connected in the vertebrate nervous system. See http://www.merlot.org/merlot/viewMaterial.htm?id=482581
  6. Draw a generalized depiction of the human brain, label the major parts, and provide a function of each. See http://www.merlot.org/merlot/viewMaterial.htm?id=482586
