Explain how the sympathetic nervous system (and endocrine system) act directly to regulate heart rate and thus cardiac output. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate) and explain how the mechanism operates to alter heart rate.Explain how the parasympathetic nervous system acts to directly regulate cardiac output (1 mechanism). Discuss each mechanism separately including a detailed description of each mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate). Make clear how each affects cardiac output. This shoul require about half a page.Explain in detail the Frank-Starling law of the heart. Be sure to define what it is, and describe how it operates (the mechanism). Explain why it is an important way that cardiac output is regulated. Demonstrate your understanding by describing a particular scenario when it would operate and its significance.

Which of the following is true

Select one:

a. Vasomotor syncope may occur when you lie down after standing up for a long time

b. Vasomotor syncope is caused by increased venous return, which causes excessive stimulation of the baroreceptor reflex

c. Vasovagal syncope occurs in response to a disturbing situation that causes over-stimulation of the SNS

d. Contraction of the lower leg muscles helps to prevent vasomotor syncope because it increases the pressure gradient from the peripheral veins to the right atrium

Our skeletal muscle is a fascinating biological tissue able to transform chemical
energy to mechanical energy. It is the most abundant tissue in the human body
(40-45%) of total body weight and provides strength and protection to the
skeleton.
1. Pick any musculoskeletal activity in daily life or sport and identify the main
muscles responsible for the movement and their roles in the movement
2. What are the typical types of fibers in these muscles, how are these fibers
organized and how does this architecture affect your selected movement from
a functional perspective?
3. What are the main factors that determine the force generation in these
muscles?
4. How is the mechanical behavior of a single muscle fiber in tension different
from the whole muscle? What is the functional value?
5. Do your selected muscles cross more than one joint? What are disadvantages
associated with muscles that cross more than one joint?
6. Draw a free body diagram for your movement and calculate the muscular
strength of one of these muscles. What factors affect this muscular strength?
You may make any assumptions as needed
7. Calculate the muscular power and muscular endurance. Again, make
assumptions as needed
8. Model the activity of one of your muscles using a muscle model from the
slides or the Literature. Describe the role of each element
9. How are these muscles and thus the activity affected by age?
10. How are these muscles and thus the activity affected by pre-stretching and
exercise?

  1. Anna is a 52-year old female, who is 5’4”, and weights 130lbs. You tested Anna’s 1-mile outdoor walk, and determined she was able to complete 1-mile in 12:45, with a post-walk HR of 147 bpm. What are each of the following:
    1. Absolute VO2 max
    2. Relative VO2 max
    3. Absolute and Relative VO2 at 70%
    4. MET level at 70%
    5. Calorie expenditure per minute at 70%

Frances is an 82-year-old woman who suffers from macular degeneration, osteoporosis, and arthritis. Since her husband died a year ago, she has moved from their family home to a small one-bedroom apartment. Her eyesight is progressively getting worse, making it diffucult to go to the grocery store or even to cook (for fear of burning herself). She is often lonely; her only son lives an hour away and works two jobs, but he visits her as often as he can. Frances has lost her appetite and, as a result, often skips meals during the week. She has resorted to eating mostly cold foods. These are simple to prepare but seriously limit the variety and palatability of her diet. Also, she wears dentures and has trouble chewing tough meats and foods with crisp textures. She is slowly losing weight as a result of her eating patterns and loss of appetite. Her typical diet usually consists of a breakfast that may include 1 slice of wheat toast with margarine, honey, and cinnamon, and 1 cup of hot tea. If she has lunch, she normally has a can of peaches, half of a turkey and cheese sandwich, and a glass of water. For dinner, she might have half of a tuna fish sandwich made with mayonnaise and 1 cup of iced tea. She usually includes one or two soft cookies at bedtime. Answer the following questions about dietary assistance for Frances.

What other questions would you ask Frances to get a better sense of her nutrition status?
