  1. My 8-month old son has a skin rash. The doctor prescribed hydrocortisone which is an anti-inflammatory drug that acts to stabilize the lysosome membranes. Explain why this effect reduces cell damage and inflammation. Why is this steroid hormone packaged in an oily based cream and applied topically (on the skin)?
  2. An individual arrives at the hospital with a very rare disease. This disease is typified by the destruction of Ribosomes in the cells. Describe the immediate and long-term effects this would have on her physiology?
  3. Three weeks ago, we were in the middle of a record heat wave. A number of elderly people visited their health care providers complaining of feel terrible. Most of the patients had cool and clammy skin and low blood pressure. What is their problem? What can be done to reverse it?
  4. You are an athlete and running for 5 miles this morning. The new coaching intern was asked to fill the water bottles with Gatorade. He misread the printed instructions and filled them with water. Is this an acceptable predicament or not? Briefly explain why

It's now possible to diagnose some nervous system disorders using genetic testing. One example is Huntington's Chorea, which slowly robs you of motor and cognitive function until you die, typically before age 55. Would you want to know if you had the gene that would lead to you developing this disease? Why or why not?

A decrease in plasma volume will decrease plasma hydrostsatic pressure. This can be detected by the cardiovascular baroreceptors which send a signal to the cardiovascular control center which sends nervous impulses to the arterioles to constrict. Constriction decreases flow to the capillary beds, in turn decreasing flow out of the capillaries at the capillary beds served by this arteriole. This prevents further decrease in plasma volume.

Jim is lifting weights. Holding a 20lb weight down by his side, he bends his arm at the elbow, contracting his bicep, and holds the position until he reaches muscle fatigue. Briefly describe how the Henneman Size Principle relates to this example. List the steps of muscle fiber recruitment necessary for the initial lift and subsequent fatigue. Include a short summary of the muscle fiber types, and the properties that contribute to the speed of contraction, recruitment pattern and metabolic activity.
