Neurotransmitters are chemical substances that neurons use to communicate with other neurons, muscles, and glands. List 3 neurotransmitters and state their action.  List 2 toxins that affect neurotransmitters.  State how they affect neurotransmitters. 

Compare three different methods of analyzing YOUR body weight/body composition.

Compare three different methods of analyzing YOUR body weight/body composition. One of the three methods must be the Body Mass Index. Additional methods include, but are not limited to; skin fold analysis, underwater/hydrostatic weighing, electrical impedance, height-weight chart, military measurements, BodPod, etcetera. 

What three methods did you choose?

What is your score or # for each of the readings?

What is considered healthy?

Are you in the healthy range for all three methods?

What can someone do to improve their measurements if they are not in a healthy range?
Need a place to get measured? Come by our state-of-the-art fitness center and they can do BMI and electrical impedence for you, find a third measurement somewhere else and you are set.

Explain how the body maintains homeostasis with regard to blood calcium levels.

Explain how the body maintains homeostasis with regard to blood calcium levels. What does the body do if the blood calcium levels are too LOW? How does it detect this and how does it respond (identify and discuss the stimulus, receptors, control center and all of the effectors involved)? What does the integument have to do with all of this? Be sure to describe all of the hormones involved in this homeostatic mechanism.If a tumor was to develop in the parathyroid gland, how would that affect blood calcium levels? Why is a compound fracture more serious than a simple fracture (other than broken skin)? How can you tell the difference (anatomy- and physiology-wise) between a stress and a pathologic fracture?Why is a cast needed for proper healing of a bone fracture? At what point in the fracture healing process is the bone most vulnerable? When does it start to become less vulnerable? Explain how one could prevent osteoporosis through the proper diet (what would need to be consumed?) and exercise. Why is diet and exercise important for healthy bones? Why is diet and exercise important for healthy bones?

What is hyaline cartilage? Where is it found? Why is more of it found in growin

What is hyaline cartilage? Where is it found? Why is more of it found in growing children and adolescents than mature adults?Compare and contrast intramembranous and endochondral ossification in a developing baby(fetus). For which bones do these two types of ossification apply? How is the building of bone different for both of these processes?For endochondrial ossificaiton, where is the first ossification center located? The second? Which bones display interstitial growth? interstitial growth is most like what form of ossification? Explain. How are both osteoblasts and osteoclasts involved in appositional bone growth? Describe the different zones of growth at the epiphyseal plate. How does growth at the epiphyseal plate explain how children’s bones grow longWhat is bone remodeling and what are the two processes that control bone remodeling? Why is exercise important for preventing problems like osteoporosis? Explain how various hormones can actually affect bone growth and remodeling.Apply your knowledge: Andre the Giant, well-known for his role in the movie The Princess Bride, was thought to have a condition referred to as “gigantism.” This is caused by an abnormally high production of growth hormone. Explain how this could lead to Andre becoming a giant.Apply your knowledge: Achondroplastic dwarfism occurs when there is a mutation in the fibroblast growth factor gene (can be spontaneous or inherited) that causes abnormal growth of cartilage. This results in individuals with short stature and short limbs but yet their heads that relatively normal in size. Explain how this may occur knowing what you know about how bones develop.Explain why osteoporosis is more likely to happen in elderly women

View HBO movie titled, “And the Band Played On.” The movie is 140 minutes in length and stars Matthew Modine. This movie is a chronicle of how HIV/AIDS was researched and made public in America. Matthew Modine, stars as Dr. Don Francis, a researcher at the Centers for Disease Control and Prevention who seeks to uncover the cause of a number of mysterious deaths. With little funding, not only must he fight the disease, but also fight a disinterested public, the government, the media and even the communities where the mysterious virus strikes hardest. But as the death toll mounts, public interest is stirred and Francis’ research becomes a desperate race against time.
You can view the movie on cable, Netflix or you can download the movie for free at the following link: https://vimeo.com/85778803
Write up a short commentary about one of the subtopics of the film that you found interesting. This should be about 200 words. Please note that I’m not looking for a summary of the movie. I’m looking for your impression of the way it was dealt with by the characters. For example, what obstacles did the physicians, epidemiologists and other scientists meet with in trying to solve the mystery? How did human nature interfere with their efforts?
You can focus on a single topic. Potential topics include, but are not limited to, the following:
a.  how they realized that they had a potential epidemic on their hands,
b. what they went through to determine how it was transmitted.
c. what obstacles they went through to they tried to assemble the clues and data to solve the mystery.
d.  target populations, 
e.  efforts by epidemiologists to tracking the disease transmission 
f.  how the politics of science put road blocks into their efforts 
g. identifying the viral microbes 
h. government agency intervention 
i.  eliminating the HIV virus from the blood banks 
j.  human emotions
