Part A
This assignment consists of five questions. Each of your responses should be one or more paragraphs long, depending upon the depth of the question. An answer consisting of only a few short sentences is insufficient and will receive a poor grade. Be sure to cite any and all sources correctly so that your academic integrity is not called into question.
Copy the following questions, add your answers, and submit them below in one attached document.
1. Describe the different levels of organization within the peripheral nervous system. Why do you think there are multiple motor divisions but only one sensory division? 2. Describe the difference in the function of hyperpolarization in action potentials vs. hyperpolarization in graded potentials. 3. Explain the difference between an electrical synapse and a chemical synapse. Which types of tissues will use electrical synapses? Which tissues use chemical synapses? 4. Discuss the primary functions of cerebrospinal fluid. How does the arrangement of the CSF network facilitate the spread of diseases such as meningitis throughout the nervous system?
5. Chapter 12 discusses the importance of sleep to healthy human physiology. Discuss the stages of sleep and what consequences may result from interrupting sleep in various stages.
NOTE: Your essay answers to these questions MUST be in your own words. Do not copy/paste any text into your answers unless you are including a properly cited brief direct quotation. I am looking for your own explanations—this is your opportunity to demonstrate what you know about these topics. The best approach will be to pretend you are explaining things to someone you are tutoring.
Part B
What are some common misconceptions about the brain? Post what you know about one or more of these topics, or conduct some basic research and share what you learn: the reptilian brain, left/right brains, brain death, etc. Why do you think these ideas are perpetuated if they are inaccurate?
Original Post – Present your outside source(s) and then summarize, in your own words, the misconception that you researched and why people still believe it. Be sure to cite your source and include a link or copy/paste (References) a direct quotation from the most relevant portion of the source to enable your classmates to view and evaluate the information.
