Need a reminder? The key ideaShow
The adrenal medulla makes adrenaline and noradrenaline, the hormones of fight or flight, under the control of nerves. The cortex makes glucocorticoids (cortisol), mineralocorticoids (aldosterone) and small amounts of androgens, and ACTH controls the cortex. Addison's disease is a lack of the cortical hormones. Cushing's syndrome is too much cortisol.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Start: mg/dL. The rises are assumed values.
Plan. New level old level .
Step 1. . mg/dL.
Step 2. . mg/dL.
Step 3. . mg/dL.
Answer: mg/dL; mg/dL; mg/dL.
Check. A larger rise gives a higher level, and each answer is above mg/dL.
Watch out. The rises are chosen to show the method. Adrenaline raises the glucose by breaking down glycogen, and the real rise depends on the person.
