Document Summary

Some of you are beginning to ask about how to study for the final. However, you still must study the text. The text expands on what i say in the lectures and so while. Lots also ask me how to study the videos. You should treat the videos just like a class lecture. That is, take notes on what the speakers say just like you were listening to me. Then study those notes just like a regular class. I put those there mostly as illustrations and to motivate you. I have included test questions from each of the videos in the test question pool. Not every one will appear on your specific exam because of the way the computer randomly selects questions. Let me be clear that you could receive a question on any video. That means there are five weeks of videos. Please email me as soon as possible so that i can remove the video from the exam.

The Soccer Mom:

A Case Study on the Nervous System

by

Jennifer Bolognese, Misti Coronel, Anita Intorre, and

Phil Stephens Biology Department Villanova University

Part I—At the Soccer Game

Thirty-two-year-old Phyllis Jackson was sitting on the bench at the side of the soccer ?eld, sipping a bottle of

Gatorade. Her husband, Steven, sat next to her with a concerned expression. “I’m really worried about you, honey,” he said.

“I’m just a little dehydrated; I’ll be ?ne.”

“If this were the ?rst incident, then maybe I’d agree with you. But your boss has been on your case about your lack of concentration at work, you forgot to pick up the kids from school last week, and quite frankly, you haven’t exactly been yourself with me lately. Now you’re having fainting spells during games? Something doesn’t seem right.”

“I know things haven’t been going well for me lately, but I don’t know why. I try so hard at work, at home, with the kids, to be a good wife. So maybe all this stress has made me a little unfocused and disoriented. What do you want me to do about it?” Phyllis said, blinking back tears.

“I think you should see a doctor,” Steven replied, putting his arm around her and drawing her close. “The kids are getting worried, too.”

Phyllis sighed. “Alright, if it will make you feel better. I really just think I need some time to relax, though.” “Well… I could drop the kids of at my sister’s tonight; that would give us a little free time…”

“That’s really thoughtful of you. I could de?nitely use a quiet night at home, maybe even go to bed early.” Steven seemed disappointed.

Part II—The Doctor Visit

“So, what seems to be the problem, Mrs. Jackson?” Dr. Warner asked Phyllis.

“My husband wanted me to come in and see you after I fainted during my soccer game Saturday. I’ve also been having some problems at work, but I think I’m just stressed.”

“What kinds of problems have you been having at work?”

“It’s been hard to concentrate on tasks. I’ve also had some problems typing—I’ve been making more errors than usual, and oftentimes my ?ngers will go numb.”

“I see,” said Dr. Warner, taking a few notes on his clipboard. “According to my records you are not on any long term medication. Have you noticed any problems outside of work?”

“Well, my husband has been complaining about our personal life lately. And last week, I completely forgot that I was supposed to pick up our two daughters after school. I’ve been feeling really tired lately; even my coordination seems of.”

“How long has this been going on for?”

“A few weeks, but this isn’t the ?rst time. These problems seem to come and go, but it’s getting to the point where I can’t just ignore them anymore. I don’t know, maybe I’m just depressed.”

“Why do you say that?”

“My mother suffered from depression throughout my childhood.”

“Well, depression certainly could cause some of the symptoms you’re experiencing,” Dr. Warner said thoughtfully. “Is there a history in your family of any neurological disorders?” “I don’t think so. I have some vague recollection of my grandfather in a wheelchair when I was really young, but I don’t know what was wrong with him.”

“Okay,” said the doctor, nodding. “Well, the few preliminary tests we’ve run show that you are not pregnant, and that you are not going through menopause. I’d like to send you to see Dr. Thrush, a friend and colleague of mine. She is a neurologist at the local hospital and she will run a few tests to explore your symptoms a little further.”

Questions: Analyze

1. Using the information provided thus far by both Parts I and II, answer the following questions.

What problems both stated and unstated does Phyllis seem to be experiencing? What pieces of background information (patient environment and social/family history) have been provided by the family?

Part III—Diagnostic Tests

Dr. Thrush looked over the results of Phyllis’s Magnetic Resonance Imaging (mri) and evoked potential tests. She was thinking how glad she was that Steven had accompanied Phyllis on this visit as she showed them the MR images of Phyllis’ brain.

“The machine took pictures of Phyllis’ brain in slices. The dark areas are the brain tissue, Phyllis, and the white areas in the middle and around the outside are the cerebrospinal ?uid.”

“Is that normal? Am I ok?” Phyllis asked. “And what are those little white dots in the tissue?”

“The white dots are what concerned me,” replied the doctor. “So we did another type of mri, called dark ?uid, so that your cerebrospinal ?uid would not show up white.”

“But I still see the white dots in my brain tissue. What does that mean?”

The doctor looked down, knowing that this was never an easy thing to tell a patient.

“I am afraid that this indicates that there are plaques or scars in your brain, and that you may have multiple sclerosis.”

Tears began to form in her eyes as Phyllis squeezed her husband’s hand.

“I am afraid that the evoked potential test and the elevated levels of myelin basic protein in you cerebrospinal ?uid indicate the same thing.”

Questions: Evaluate and Apply

2. Distinguish between the relevant and non relevant symptoms/lab results needed to form a diagnosis. Of the relevant symptoms/lab results, rank them in priority and defend your answer.

3. Given what you know about the role of myelin in action potential propagation and the key information previously identified in questions 1 and 2, explain why multiple sclerosis is the appropriate diagnosis.

Part IV—The Diagnosis

Dr. Thrush informed Phyllis that she was probably suffering from the relapsing-remitting form of multiple sclerosis (ms), in which relapses of symptoms are separated by periods of remission. ms is a disorder in which the myelination of axons is degraded due to unknown factors. The most commonly accepted explanation is that ms is an autoimmune disorder in which myelin in the central nervous system is attacked by the body’s own immune system. There is no known cure for multiple sclerosis. During remission, axons affected by the disorder regain their function. Voltage-gated sodium channels are concentrated in the nodes of Ranvier and the distribution changes at disease onset.

Thank you for your time with this

Economics is nothing more than the study of scarcity and choice. It's called the Economizing Problem.

Economics is also the study of human action---why people make the choices they do.

We have finite (limited) resources and infinite (unlimited) demand for goods and services. We must, therefore, use rational decisions as to how to allocate these resources so that we can produce the goods and services that satisfy as many needs and wants as possible.

Needs are those things that make life possible---food, clothing, shelter, etc. Wants are the things that make life easier---glass in windows, carpet on the floor, a refrigerator to keep your beer cold, etc.

The resources we are trying to use wisely are not confined to money. We are talking about talent, ability, drive, ambition, etc. We can't all be brain surgeons. Nor would most of us want to be. We have different needs and wants that drive our ambitions. I have 5 grandchildren. The oldest two are twins---a boy and a girl. My granddaughter graduated from Idaho University with a bachelor's and a master's degree in accounting in 5 years. She passed the CPA exam on the first try. She now lives in Panama and works for BMW. She speaks, reads, and writes 4 languages, including English. Her brother finally graduated from the University of Arkansas in May 2016 after 8 years! Why did it happen this way?? They were raised the same way by the same parents. Why was my granddaughter drove to succeed and my grandson so listless?

Then there is subjective valuation and opportunity cost. Opportunity cost is nothing more than what you have to give up to do something else. Some of you might have to roll out of the bar or the party a little before you wanted to leave just to be able to attend my class. You might also have to give up some precious sleep. In any event, you had to give up something to attend my class. That's the opportunity cost. Remember, everything you do has a price (opportunity cost) that must be paid according to Harry Browne who wrote, How I Found Freedom in an Unfree World.) To do one thing you must give up the opportunity to do something else.

When people decide to buy a product or service they must decide if it will satisfy a need or want at a price they are willing to pay. The number one reason that people buy the products or services they do is called Personal Tastes or Preferences (Subjective valuation). Everyone has a different price they are willing to pay for the same product or service. Something is only worth what someone is willing to pay for it. That's a subjective valuation. Each of us has a different intensity of demand for the same products. Things you want I may not care for at all, and the opposite may also be true. This is why there is such a variety of goods and services offered on the market.

Subjective valuation is also fluid. As your income goes either up or down it changes your valuation of products and services. Have you ever wanted something so bad you would do almost anything to get it---an i phone or I pad?---but once you get the money you think, "do I really want this?' and you don't buy it. This is common. If it were not for a subjective valuation we would all be wearing the same style and color clothes and living in similar houses, etc. Wouldn't that be a wonderful world! I'd find the tallest building in downtown Orlando and see if I could fly! It is not the similarity in people that interests me. It's the differences. It's my desire not to be like everyone else that has driven my life. Don't strive to be someone else. Strive to find and be yourself. God save me from a terminal case of conventional wisdom!

There are 5 embedded questions.

Give me an example of subjective valuation.
