Module 1—The Nervous System

Reflect and Connect

 

In previous lessons you learned about the different parts of the nervous system and nerve transmission pathways. You also learned about sensory receptors that allowed you to hear the mosquito ring tone of a phone. Various lobes of the brain were involved in processing this information, and motor pathways led to responses. This lesson focused on the neuron, the type of cell that makes up the communication pathways of the nervous system. You discovered the special parts and functions of a neuron, and you considered how these structures facilitated communication and could even accelerate the rate of communication. This leads to an appreciation of the significance of myelination and an understanding of how symptoms of diseases such as MS indicate interruptions in communication.

 

Module 1: Lesson 7 Assignment

 

Retrieve the copy of the Module 1: Lesson 7 Assignment that you saved to your computer earlier in this lesson. Complete Part 3—Reflect and Connect. In Part 3 you will have the opportunity to answer a series of questions based on data. This question is similar to the closed-response written question that you will write on the Diploma Exam at the end of this course. Save your completed assignment in your course folder. You will receive instructions about when to submit your assignment to your teacher later in this lesson.

 

Reflect on the Big Picture

 

In the Big Picture at the beginning of this module, you were introduced to unconscious and conscious communication in your nervous system. You now know that communication within or between any parts of your nervous system involve neurons. The Module Assessment involves research into Alzheimer’s disease—a disease involving major interruption in communication.

 

Research how Alzheimer’s affects the neuron and its ability to support communication. Take into particular consideration the consequences to communication when these affected neurons make up the brain. Store your research in your course folder. If you have any concerns about your research, contact your teacher.
