Questions
1. What is the electrode measuring?
The electrode is measuring the activity of the neurons.
2. Why use leeches in neurophysiology experiments?
They are easy to disset due to their large and easy to reach neurons.
3. What is the difference between a sensory and a motor neurons?
A sensory neuron produces impulses from an organ to the brain and spinal cord. A motor neuron produces impulses from the brain and spinal cord to an organ.
4. Do you think that leeches experience pain? what is pain?
Yes, I believe that they do feel pain since they have a functioning body with a working brain. Pain is defined as "hurt or suffering of the body or mind."
5. What were the two most interesting things about doing this lab?
I was able to dissect without smelling or seeing the real thing. I also enjoyed learning to read all the different types of neurons.
6. Anything you found confusing or dont like about the lab?
No, i thought the directions were clear and easy.

Unit III course evaluation
REGARDING COURSE CONTENT--THEMES AND TOPICS FOR THE UNITS
-Unit I: Cells and Genetics
-Unit II: The Body--Internal Maintenance
-Unit III: The Body--Environmental Interactions
-Unit IV: Human Populations (I know, you haven't done it yet, but you can check it out)
Which Unit did you like best and why? I enjoyed unit II the best, it related best to what I need to know for becoming a nurse and it just had my complete attention the entire unit.
Which Unit did you like least and why? Unit I only because even in middle and high school when I was learning about cells I did so horrible and I think its because there’s so much you have to know and remember that I would sic myself out.
Is there some major area of Human Biology that you feel was neglected and should be included in the course? no, not to me I learned so much that in this short period of time if you add anything else it could really overwhelm students.
MAJOR TOPICS
-Cells
-Genetics
-Oxygen/Blood/Immunity
-Food and Nutrition
-Nervous Function
-Movement
-Reproduction
-Human Ecology
Which two Major Topics stand out as particularly well presented? Why? Oxygen/Blood/Immunity, and Food and Nutrition I said these too because there were so many different view points and the book did a great job at getting into details.
Which two Major Topics stand out as having been confusing or difficult to understand? Why? Cells and Genetics, Genetics not so much I got the concept and the end of the unit but cells for sure I would say should be a unit on its own.
Other comments regarding course content: The way you set up the course was easy at least for me to check my grades, view power points, and do my homework.
REGARDING COURSE DELIVERY AND INTERACTION WITH WEBSITE AND INSTRUCTOR
Have you taken an online course before? No
How would you describe your "digital nativeness" or ease of using the computer and internet? well I can be a little challenged when it comes to the computer but the internet was easy. I only had problems getting my pictures and charts on blogger
For the following aspects of the course, please how effective each one was for you (very, somewhat, not much):
-Overall Course Welcome and Orientation Video: Very
-Unit Introduction Videos: somewhat some of them I admit I didn’t watch because I liked the power points better
-PowerPoint presentations (please indicate if you listened to the narrations): Very no narration.
-Online Weblinks: Very
-Online Labs: Very
-Lab Projects: Very
-Ethical Issues: Very
-Textbook: somewhat
-Blogs for presenting assignments: Somewhat
-E-mail or other interactions with instructor: Very
Which two aspects of the course delivery and evaluation from the above list most helped you to learn? Why? Online labs and Ethical issues
Which two aspects of the course delivery (course activities and assignments) would you recommend changing or eliminating? Why? Unit introduction videos, and maybe the blogs
Was there any part of the course website that you found confusing or difficult to navigate? Compendium review
Other comments regarding course delivery and interaction with website/instructor: no just that for me the compendium reviews were really difficult because I didn’t understand what you were expecting.

Unit Three Ethical Issue: Exercise...is the concept working?
In today’s world we have a topic that is rapidly growing, obesity. In most of today’s studies we can see that every year obesity is starting in children younger and younger. Why is this you well I am going to get into that through my essay. Some people think that our society has become obese because of the towns we live in. Others think its because we don’t exercise. What is your opinion?
James O. Hill, Holly R. Wyatt, and John C. Peters made statements that they think the way we build our communities affects our physical crisis. I agree only so far, I agree that we do have to many fast food restaurants, and not enough fun outdoor activities going on. I disagree when they stated that having more sidewalks makes people less reliant on there automobile and more likely to walk. For example we have a Target and less than a five minute walk in the same shopping center we have an Old Navy. When it is 98 degrees outside I have seen more people getting into their cars and driving to Old Navy from Target, Why? I can say that for me its because after getting out of the Old Navy I don’t want to walk back to Target. Its all about convenience, today the world is all about fast and easy that’s why we rely on fast food so much.
James, Holly, and John also stated that fast food is a big dilemma. I agree one-hundred percent with that statement and ill tell you why. They are right when they said that the super sized menu has increased our obesity. People will go to McDonalds and order food and they super size it will making sure they eat it all. Fast food restaurants’ serve foods that are high in sugar and fat yet very cheap and affordable. For us we believe that we are getting a smoking’ deal when really the fast food business is laughing because they can do all this for just pennies. They also stated that the only way we are going to change this is if it is replaced with a different deal but I don’t see that happening anytime soon.
Some people these days have stated that exercise will get of obesity completely. I disagree I believe that exercise will only reduce the number of obese cases in younger children. I also think from experience of just getting out of high school that drug and alcohol abuse is a big factor of obesity in younger adults. They get so wrapped up in the parties and drugs that they slowly stop engaging in sports and activities and I think that it greatly affects the world. Exercise only slows down obesity but if we all exercised and ate right our world would be less obese.
So do you think that obesity is ever going to get under control? Do you agree with James O. Hill, Holly R. Wyatt, and John C. Peters that its our communities that make our world obese? Or is it the exercise that needs to be increased? They all have very great opinions and very striking evidence. Will people listen to them and change our worlds problem?
I can see that only a few people will really get into these issues but its better that some people change rather than none. I will definitely start eating right and working out more. I still see people driving rather than walking or riding a bike only because it is so convenient. Fast food is still going to serve foods that are high in fat and sugar yet sadly enough we are still going to give in and order it. Our world will never be obese free but hopefully the younger generations will have less cases of obesity.

This is what i ate yesterday.
-How healthy a daily diet do you think this is? Why?
i think that this is an okay diet but i find it hard for me now that i am pregnate. All i want to do eat and i want to eat things that arent always so good for you.
-What would you change about this day's eating, if anything?
less butter
-Do you find this kind of nutritional tracking helpful? Why or why not? yes, because it keeps you aware of what you are eating and how bad it really is.
Compedium Review 4 continued
Diabetes
•Type I diabetes—no insulin produced by pancreas
•Type II diabetes (obesity-related)—cells become resistant to insulin and can’t utilize glucose
•Type I diabetes—no insulin produced by pancreas
•Type II diabetes (obesity-related)—cells become resistant to insulin and can’t utilize glucose
Compendium Review 4
Digestion
This is a picture of the GI track. It start with the mouth, teeth chew and the saliva is used in digesting and the tongue allows you to swallow. Air is blocked off while swallowing, Food enters the esophagus and peristalsis begins. The esophagus moves food to the stomach. The stomach expands and the food is stored. The duodenum of the small intestine receives bile from the liver and pancreatic juice from the pancreas. Bile emulsifies fat and readies it for for digestion by lipase. The pancreas produces enzymes that digest starch, protein and fat. The intestinal enzymes finish the process of chemical digestion. Small nutrient molecules are absorbed at the villi in the walls of the small intestine. The pancreas produces pancreatic juice. The liver produces bile, destroys old blood cells, stores iron and store glucose. the liver produces bile and the gallbladder stores it. the large intestine consists of the cecum, the colon, and the rectum which end up and the anus. The large intestine absorbs water, salts, and some vitamins.
Nutrients
We should be provided with good energy after our food has digested completly. Obesity is on the rise due to people not eating correctly. This is a big issue. Carbohydrates are necessary in any diet but only so many should be consumed in a day.
The food pyramid is a great tool to use:
Ethical Issue: What is Food?
How is food produced? Why don't we eat spiritually and culturally? Can we improve on our health in the future? These are all question that I ask myself as i sit here and eat my fast food subway sandwich. why has our world come to this? Why is it okay that we have fast food on more than every corner? Is this the new world that we have to get used to? Is it going to change? Is the world going to become more obese now or can we change?
I can remember back when I was a little girl and my grandma would tell us that it was so important for us to cook great meals for our families. She would spend hours in the kitchen cooking home made Italian food, southern food and sometimes American food. To me it was a great cultural experience and now that I am living in my own home it seems that cooking dinner, which happens only so often, is the only meal you cook at all. I wish that i could keep my grandma in my back pocket and pull her out to help me come up with great breakfest, lunch and dinner meals.
Just think obesity is on the rise in our country and most people want to blame it on fast food. Michael Pollan says that we should look at the nutrients in the food we are eating. If you think about it subway is considered a fast food but yet it is healthy and has great nutrients for you. So I think that the obesity problem is junk fast food plus lack of exercise. In my mind I see people that I know and they are always hurting for money but they eat fast food 3 or even 4 meals a day. To me i think that going to the grocery story and buying food and then going home and making it you would save more, look and feel better. I could probably say that eating at restaurants is not very good for you, well at least the chain restaurants. I used to work at red Lobster and we would get shipments in and stuff and just looking at it get cooked know what it was is just not pleasant.
Yet i cant stop thinking that we have a real problem on our hands. Why is it so hard for our country to eat healthier? I can only remember having great meals at my house when we had lots of people coming over. I can sit here today and remember that and look at today and say wow I am just like my mom. I only cook when there are people over and they ask me to cook. I admit i eat out a lot. My fiance eats out everyday at work and to me that would get old but than it hits me it is old and i eat out too.
Michael Pollan says we should eat only foods with nutrients in them and I agree but I also think that we should eat foods that are part of our culture. Like I am Italian and I want to eat pastas and bread sticks. Mix it up to don't just stick to one culture, try them all see how great they are. I think that Michael Pollan has a point that we should add nutrients to our meals so add them to your cultured food you choose to eat. Add some exercise to your life, eat less fast food, and cook more at home.
So the questions still stand: How is food produced? Can we improve on the way we eat in the future? Can we start to eat spiritually and culturally? Can we drive by all the fast food corners? These are all questions you should keep in mind. Do we want our country to become obese because were lazy and wont exercise?
