Textbook Question
Chapter 13, Problem 3AWK
From what you read in section 13.5 
draw the negative feedback control loop for cortisol secretion. Then indicate on your diagram how stress or injury would affect the feedback loop. Check your diagram with a classmate or your teacher–if you can draw it and explain it, you understand it!

The dexamethasone test involves the administration of a synthetic glucocorticoid. Knowing about negative feedback mechanisms, how do you think this test helps determine the function of the pituitary?
Since you couldn't answer one of my questions heres the last one. Describe how steroid hormones, for example cortisol, are metabolized in the body. What are the benefits of using a 24-hour urine test to measure this hormone?
Now that you have shown the endocrine response, think about the negative feedback that will occur when Ca++ levels return to normal. How will the system be turned off? Please describe where negative feedback arrow would be drawn on the diagram.
The arrow will begin at:
