Lesson 3

Module 1—The Nervous System

Reflect and Connect

 

When you were introduced to the new girl at school, you quickly withdrew your hand from the handshake. You then became embarrassed and blushed. To reflect on your knowledge from this lesson, trace the reflex arc that occurred when you withdrew your hand. Include a description of all the parts of the motor neuron that communicated with your muscles. Also include a description of the role of the myelin sheath. Reflect on why your embarrassment and blushing happened later.

 

Reflect on the Big Picture

 

In this lesson you learned about the structures and functions of the neurons. You also learned about the reflex arc. Research the possible connection between the cause and symptoms of Alzheimer’s disease and the parts of a neuron. Alzheimer’s disease affects neurons in the brain and interrupts communication between neurons.

 

Conduct an Internet search using search terms such as “Alzheimer’s disease,” “Alzheimer’s + brain or neuron,” and “Alzheimer’s research.”

 

You should also consider the effects of the disease on a patient’s ability to respond rapidly to a stimulus that could be life threatening. Apply what you have learned about the reflex arc in your response. Store the results of this research in your course folder. You will use this information when you complete the Module Assessment.

 

Going Beyond

 

Listen to Michele Boden’s documentary “The Alberta Disadvantage,” a CHED radio documentary about the extremely high rate of multiple sclerosis in Alberta. Use search terms such as “The Alberta Disadvantage,” “Michele Boden,” or “CHED documentaries” to find this documentary on the Internet.
