Discussion Board 3: Skeleton Story

/in /by

Prompt:

Comic book characters have all kinds of exciting and rare anatomical and physiological features that define their storyline. Apply what you have learned in Hands On Lab: Skeletal System to design your own comic book character (superhero or villain). You do not need to be a comic book expert at all!

You will need to describe changes to the skeletal system (Wolverine and Mr. Glass are not allowed to be copied but may certainly be used for inspiration) on a detailed level that gives your character some benefit. Conversely, you will also need to describe a weakness or cost to the body from this change to the skeletal system.

This is up to you! Have fun with it but base your choices on evidence. If you could enhance one part of our skeletal system to make us superheroes or supervillains, what would it be?

In your posts to your classmates, evaluate their choices. Is there anything you want to borrow from their design to build a better comic book character? Are you able to offer them advice to how their design could be improved? Is there a weakness that they haven’t realized?

Example: I may want to have a character who can easily move through treetops so I would redesign the bones of the upper body. I would discuss this in correct anatomical terms (Ex: femur, proximal) and include details on a cellular level (Ex: osteoblast). I may also look at the skeletal structure of animals, like an orangutan, to help guide me. The weakness may be how the skeleton may now be off balance so mobility would be affected or could be an issue with the joints now being overworked.

Part 1: Initial Post (Worth up to 50 points)

• Length: 250-500 words• You will need to use at least 3 reputable scientific references to support your post (not including your textbook). Reputable sources= peer reviewed scientific journal articles, accredited websites, or books. Google, Wikipedia, etc. are not acceptable sources.

Part 2: Responses (Worth up to 50 points)

Comment on at least 2 classmate’s discussion submissions.

• Each comment must be 150-200 words!o Evaluate their posto You are looking at their design choice to offer constructive feedback o Offer questions or responses to what is said. Offer Research that backs or refutes a point being made (“Good Jobs”, or “I agree” are NOT allowed as your response!!).

How will I be graded?

The rubric to this assignment is located in the same spot on Blackboard where this guideline is located, as a separate document. Take a look prior to starting the assignment and let your instructor know if you have any questions regarding expectations.

What kind of sources should you use?

Your information must be credible, accurate, and well supported by evidence. The best sources of information are the research journals and the books as well as webpages maintained by professional societies and organizations. Search for articles and academic material should start with the electronic databases of libraries such as FTCC’s Paul H. Thompson Library (opens new window), PubMed (opens new window) or other such resources. When in doubt about material, use CARS checklist (opens new window) to see if it can be used in discussions and writings.

Don’t forget to CITE!

You must cite all sources. Citation format must be MLA or APA (Visit the Purdue Owl Writing Lab (opens new window) for instructions on proper formatting)

Examples: In science we primarily use APA. These are basic examples of common citations. Please see the Purdue Owl (linked above) for more details/examples.

In-text citation: When you are paraphrasing from an author, so whenever you a

taking information form a source and putting it in your own words.

Cell Biology And Genetics CASE 1!!!!

/in /by

MN551-1: Integrate knowledge of advanced physiology and pathophysiology across the lifespan with the clinical implications for the advanced practice nurse.

 

 

ONLY ADDRESS CASE 1!!!!!

 

 

 

Case Study: Cell Biology and Genetics

 

Below are several case studies. Your instructor will either assign you a case study or have you select one. If all of the case studies have not been covered, your instructor may assign a case study that no one has covered. Be sure to integrate your knowledge of advanced physiology and pathophysiology across the lifespan with the clinical implications for the advanced practice nurse.

 

 

Case Study Posting Requirements

1.    Make sure all of the topics in the case study have been addressed.

2.    Cite at least three sources; journal articles, textbooks, or evidenced-based websites to support the content.

3.    All sources must be within five years.

4.    Do not use .com, Wikipedia, or up-to-date, etc., for your sources.

 

 

Case Study 1

Marsha and Clement are both carriers of sickle cell disease, a disease that is autosomal recessive. Their first child, Amelia, does not have the disease. Marsha and Clement are planning another pregnancy, but they are concerned about their second child having the condition. Clement’s dad died from complications of sickle cell disease shortly before Amelia was born.

1.    Draw a Punnett square to determine the likelihood of Marsha and Clement having a baby with sickle cell disease. What is the chance the baby will be a carrier of the disease, just like the parents?

2.    Marsha suggested to the nurse at the local family planning clinic that if the baby were a boy he might have a higher risk for developing the disease, just like his grandfather. If you were this Practitioner, how would you respond?

3.    When Amelia, who does not have sickle cell disease, grows up and marries someone who does have the disease, how likely is it that her children will have the disease?

 Case Study 2

Maria is a sedentary, 68-year-old woman who is overweight. She complains that her hands and feet are always cold, and she tires quickly when cleaning the house. At her most recent visit to her doctor, her blood pressure was 184/98 mm Hg. She has edema around her ankles and legs, and her physician is concerned about an echocardiogram that indicates Maria has an enlarged heart.

1.    Identify two reasons why Maria will have tissue ischemia. How might this lead to hypoxia?

2.    What two early and reversible changes occur to tissue cells when they are hypoxic?

3.     What specific type of cellular adaptation has taken place in Maria’s enlarged heart? What made you come to this conclusion?

4.    Predict why Maria’s heart has become enlarged. Why doesn’t this enlargement give her the same cardiac strength and endurance as a well-trained athlete?
Case Study 3

Kevin worked for 10 years at a uranium mine, excavating uranium for a nearby nuclear power plant. Now, 25 years later, he has small cell lung cancer. Kevin is anorexic and has lost a considerable amount of weight. His muscles are wasting, and he is weak. He tries to move around the house throughout the day but tires easily. It has been difficult for him to access care, and the treatment for his cancer is just starting.

1.    With the ongoing exposure to the ionizing radiation, DNA damage occurred. Outline the three stages of carcinogenesis that occurred after his exposure to radiation.

2.    Kevin is normally a fit and active man, and his wife often commented on how much food he used to eat after a day at mine. Why would there be muscle wasting and weight loss now? Explain your answer using your

3.    knowledge of the metabolic changes seen with cancer.

4.     In some cancer patients, muscle weakness may result from the production of onconeural antigens. Describe the effects of these antigens. What form would this process likely take in Kevin’s situation?

 Case Study 4

Felicity is a very busy 29-year-old woman in a professional career. She has diabetes mellitus, and is also pregnant for the first time. Due to her busy schedule, it took her three weeks to visit the family doctor to have the pregnancy confirmed. Felicity became very concerned when her physician asked whether she had been taking folic acid. It was all Felicity could do to remember to manage her insulin levels, and taking folic acid supplements was something she hadn’t even considered. Her doctor told her to take 600 μg of folic acid daily and advised Felicity to return later for maternal serum marker testing.

1.    Explain the potential teratogenic effect of folic acid deficiency on the developing fetus. What other risk factor is noteworthy in Felicity’s case?

2.    What is the benefit of maternal serum marker testing? What other test would be particularly useful to monitor the development of Felicity’s baby in this situation?

 

3.    When is the fetus most vulnerable to the effects of teratogens and why?
