Document Summary

To survive in the world we have transformed, we must learn to think in a new way. As never before, the future of each depends on the good of all. This is the last lecture of the year. Your exam i think is on december 11th. It will be a 3 hour exam but probably about 1 hour more than you need. The structure will be similar to the mid- term (short answers and multiple choice). I tried to be more specific this time. You will have questions from both the lectures and the tutorials. Some of the hardest questions were from tutorials. There are 2 readings for the tutorial this week which are listed on the intranet. Make sure to quiz him and read the information. No, it is from october onwards. (if you didn"t write the exam then it will be cumulative so study previous material. ) It wasn"t all numbers but there was a reasonable number.

Short Answer Questions: Using essay, answer both of the following questions. Be as detailed as possible.

1.Explain the synthesis of thyroid hormone (T3 and T4). Be sure to include the location of the synthetic events within the thyroid follicle.

2.Choose a hormone from the following list and explain what simulates its release and at least 2 physiological effects of the hormone. Be sure to include all appropriate anatomical structures involved. Basically, you should include as much information from those lecture diagrams as possible. Choose one from: GH, TSH, ACTH

A geneticist studying agriculturally important traits inanimals, designs an experiment in chickens to determine the numberof genes involved in determining the number of eggs layed permonth. A variety of chicken that lays 120 eggs per month is crossedto a variety of chicken that lays 200 eggs per month. Theiroffspring (F₁ generation) lay 160 eggs per month. TheF₂ egglaying phenotypes vary greatly over a range withthe highest and lowest equal to the parental extremes. A total of13,000 F₂ offspring are produced with 12 laying 120 eggsper month and 13 laying 200 eggs per month.

How many gene pairs are involved in determining the number ofeggs a chicken lays? See the last page for a tutorial oncalculating number of polygenes.
What is the average contribution, in eggs, of each activeallele? _______________

Additional information for the polygene question.

To calculate the number of polygenes: 1/4ⁿ = ratio ofF2 individuals expressing either extreme phenotype. In the examplegiven in your textbook and mini-lecture of wheat kernel color, 1/16of the progeny were either dark red or white like the P generation.You need to solve the equation 1/4ⁿ = 1/16. n = thenumber of genes. In this example n=2, there are two genes involvedin wheat kernel color.

n	Individuals expressing either extremephenotype	Distinct phenotypic classes

2	1/16	5
3	1/64	7
4	1/256	9
5	1/1024	11

When you are faced with a medical case and do not know how to approach it or have questions, what do you do? Even experienced nurses, dentists, doctors, and pharmacists will go to their smartphones and begin searching for answers. So much information is available. How do you know what information is reliable and valid? The purpose of the journal assignment is for you to practice finding, evaluating, and summarizing resources around key concepts that are presented throughout the module, which is relevant to your specific area of interest. This journal should be valuable to you; you can collect sites, resources, and readings that you find helpful to your learning.

This module will focus on the following topics that examine how our body responds, or rather adapts, to environmental toxins on a cellular level:

* Cellular adaption and neoplasia

* Infection, immunity, and inflammation

* Hematological disorders

Instructions:

Search for, read, and incorporate (3) other readings in regards to either (tumor associated inflammation in mammary cancer between humans and dogs) or (zinc and vitamin E interactions related to the inflammatory response in aging and inflammation) or both. In this area of interest that focus on cellular adaption and neoplasia; infection, immunity, and inflammation; and/or hematological disorders. You might include:

* 1-2 journal articles or websites

* Book chapters

Your summary of EACH reading should be at least one paragraph (100-200 words) and include the following information:

All references must be cited using APA Style format.

* Number of pages read

* Keywords you used to find the reading

* Link to the reading

* Why you selected the reading

* Main point of the reading

* Describe how the health deviations you read about alter normal physiology.

* Provide your key take away from the reading. This could be something that made you pause, changed your thinking, supported your thinking, or made you question something.

* In your post, respond to the following questions: How do you know that the material you have found and read is reliable? How do you know that it is valid?
