Module 1 – Case
STRESS AND THE NEUROENDOCRINE RESPONSE
STOP!!! Review the text and diagram on the Home page and the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=8746″>introductory Anatomy and Physiology tutorial before proceeding with this assignment!
Now study this diagram showing how the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5824″>body responds to stressful stimuli. Notice that short-term stress follows one signaling pathway that begins in the brain, travels out the spinal cord, and directly to the adrenal glands. Many organs of the body will receive direct stress response messages using this pathway as well. When the adrenal glands receive the signal from this pathway, they release a stress hormone that signals many systems in the body to prepare to either run away from the stressor (such as a predator or an oncoming vehicle, for example), or fight. The part of the nervous system that activates this response to acute stress is called the sympathetic nervous system. After the stressful stimulus has passed, the parasympathetic (nicknamed the “rest and digest” response) calms the nervous system and restores the normal function of the body systems, maintaining homeostasis.
The Sympathetic vs. Parasympathetic Nervous Systems
These two divisions of the nervous system counteract each other to allow the body to receive the resources it needs to respond to a life-threatening situation (more glucose to the brain to enhance thinking ability, more oxygen and sugars to the muscles to run, etc.), and then return to a relaxed state. As you saw in the diagram, the sympathetic response begins when a stressful situation is detected by your sensory nerves, which make up the peripheral nervous system, or PNS. The sensory nerve endings can deliver this message directly to the brain through cranial nerves, which gather the information we need to give us the senses of smell, sight, hearing, and taste. Stress stimuli can also be detected by peripheral nerve endings throughout the body and delivered to the brain via the spinal cord. The brain and the spinal cord make up the central nervous system, orCNS.
View this diagram to review the anatomy of the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=10056″>sympathetic and parasympathetic nervous systems.
Notice that the “rest and digest” (parasympathetic) message is delivered through cranial nervesthat originate in the brain stem, and sacral nerves that originate in the sacrum at the end of thespinal cord. The “fight or flight” (sympathetic) response originates from the spinal cord. These nerve impulses are delivered by the CNS to the effector organs responsible for reacting to the situation by either simulating the organ to take action, or calming (inhibiting) the organ to return homeostasis. In this situation, the nervous system sends a signal to the endocrine system to handle acute, or short-term stress.
When the body is faced with long-term, or chronic stress, the endocrine system predominantly responds by releasing hormones such as cortisol. You will learn more about cortisol in the next module.

Module 1 – SLP
STRESS AND THE NEUROENDOCRINE RESPONSE
As you work through this SLP assignment, you will learn more about the flexibility, or plasticity, of the brain. You have learned about how the spinal nerves can deliver messages directly to effector organs from the CNS through peripheral nerves that branch off of the spinal cord. These nerves are collections of neurons bundled in connective tissue. Neurons also communicate with each other within the CNS and establish circuits and neuronal pathways.
First take some time to work through these tutorials about how neurons communicate:
1. .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5530″>Neurons communicate with each other
2. Neurons communicate at .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5527″>synapses
3. Communication is delivered via the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5529″>axon
4. .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5538″>Synapses and neurotransmitters: Be sure to click on “Presynaptic neuron,” “synaptic cleft,” and “postsynaptic neuron.”
Throughout life, the connections between neurons in the brain develop and change according to the genetic foundations that the individual inherits from the parents, and the environmental influences to which the individual must respond. For example, the abundance of one type of neuron over another, and the neurotransmitter that each produces can be predetermined by the DNA an individual inherits. However, an individual who is exposed to chronic stress during developmental years may reinforce some response pathways more than individuals who do not experience the same patterns of stress. These points are summarized and explained further in this article “.mayoclinic.org/healthy-living/stress-management/in-depth/stress/art-20046037?pg=2″>Stress Management,” provided by the Mayo Clinic. Read this brief article before continuing to the requirements for this SLP.
Continue your reading on how the brain handles stress and the idea of plasticity at .brainfacts.org/about-neuroscience/ask-an-expert/articles/2012/long-term-stress-and-the-brain/”>BrainFacts.org, a public information initiative of the Society for Neuroscience, The Kavli Foundation, and Gatsby. Read the article, “How does the brain handle long-term stress?” and follow the link to the article, “Effects of Stress on the Developing Brain” in the right-hand column of links provided on this page.
Address these questions in paragraph format to complete the SLP assignment for Module 1:
1. What is a neurotransmitter and what is its function?
2. What neurotransmitter is mentioned in the article, “How does the brain handle long-term stress?”
3. How is short-term stress described in this article?
4. Do a little independent research on the hippocampus. Where is it located in the brain? Briefly describe its function and neurogenesis. Insert a labeled picture into your assignment illustrating its location.
5. How is long-term stress differentiated from short-term stress in this article? What brain region is involved in this comparison and what is its general function? Insert a labeled picture of this region into your assignment illustrating its location in the brain.
6. After reading the article “Effects of Stress on the Developing Brain,” explain the implications of chronic stress on the brain and the rest of the body reported by the authors. What examples of chronic stressors are included?
7. What components of parental care are described as being important determinants of brain development in this article? What genetic influences are described as relevant to the ability to handle stressful environments?

Include a References section that lists these and any additional sources you used (refer to the Background page). For any additional research you are required to do to complete your assignment, please use scholarly references such as a peer-reviewed journal article or a government-sponsored or university-sponsored website. As you read through your sources, take notes from your sources and then write your paper in your own words, describing what you have learned from your research. Direct quotes should be limited and must be designated by quotation marks. Paraphrased ideas must give credit to the original author, for example (Murray, 2014).Direct copying from “homework help” websites will not receive credit.
Now that you know about the immune response, return to the article .dartmouth.edu/fall-2010/the-physiology-of-stress-cortisol-and-the-hypothalamic-pituitary-adrenal-axis#.U-aGCONdVyw”>The Physiology of Stress: Cortisol and the Hypothalamic-Pituitary-Adrenal Axis in the Dartmouth Undergraduate Journal of Science and read the section related to the immune system in closer detail. Using this as a starting point, complete the requirements below using paragraph format to address each topic:
Paragraph 1: Introduction
Note that the inflammatory response and the complement system are mentioned in the article. Now learn more about the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=8622″>inflammatory response and the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=8631″>inflammatory mediators. You will find information on the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=8600″>complement system as well. Do a little research on these components and provide a paragraph explaining the normal function and steps associated with signaling these components. Identify where in this cascade of signaling events that cortisol is thought to interfere.
Paragraph 2: PTSD and the Complement System
Now compare the theory mentioned in the Dartmouth article to the findings in this study on .ncbi.nlm.nih.gov/pmc/articles/PMC2834673/”>PTSD and the complement system. Focus on the Abstract and Discussion sections of this study on PTSD. Address the following questions:
What did they find in common among PTSD patients?
How does alteration of the complement affect the inflammatory response?
Paragraph 3: Inflammatory
Response and the Brain
Finally, read .dana.org/Publications/ReportOnProgress/Consequences_of_the_Inflamed_Brain/”>The Consequences of the Inflamed Brain and draw connections between the inflammatory response and brain function and behavior. How are the CNS and the immune system interconnected? How does the inflammatory response affect mood and behavior?
Which component of the nervous system reacts to an infection? What are the implications for mood and behavior if the inflammatory response is prolonged? What types of things might cause the inflammatory response to become prolonged or exaggerated?
Paragraph 4: Conclusions
To complete this assignment, “connect the dots” between the influence of stress on the immune system, the potential effects that PTSD can have on the inflammatory response (remember this occurs after an extremely stressful event and is related to dysregulation of cortisol), and the perpetuation of depression and other symptoms of PTSD.

You must complete your Case 3 assignment before you can proceed with this assignment.
In this module’s SLP assignment, you will take a break from the anatomy and physiology of stress to analyze the work you have done so far, specifically in your Module 3 Case Assignment.
The readings you accomplished for Module 3’s Case Assignment are quite new scientific theories that are currently being tested by scientists who are trying to figure out why individuals suffer from behavioral issues such as depression and PTSD. The scientific and medical communities have collected a lot of evidence that stress plays a very big role in not only creating these behaviors, but also perpetuating them. We still have a long way to go and a lot of unanswered questions!
By completing Case 3, you have participated in the .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=10647″>scientific method. After you view this linked animation, use this .pearsoncustom.com/mct-comprehensive/asset.php?isbn=1269879944&id=5624″>diagram as your reference point to complete the following components of this assignment:
In which part of the Case Assignment did you address Step 1, “observe and generalize”?
Which part of the Case Assignment required you to accomplish Step 2, “formulate a hypothesis”?
Did your hypothesis contain information that can be accepted as the absolute truth? If not, what information was missing? (HINT: Think back to the studies about cortisol and PTSD.) Based on the information that was missing from your hypothesis, what could you test in order to obtain more information on the unknown piece?
Do a bit of research on the technology available today that could facilitate this test. Examples of new technology include brain imaging, blood chemistry and hormone level tests, CAT scans, MRIs, and DNA mapping. What step of the scientific method does this require?
Now that you have some additional information, briefly and in simple terms, describe how you would test the missing information and which step of the scientific method this accomplishes.
