Module 2 The Endocrine System
Lesson 1.2.3
Lesson 3—The Adrenal Gland
Get Focused
When you studied the sympathetic nervous system in Module 1, you learned about the “flight or fight” reaction, which refers to the tendency in stressful situations to run away or stay and work through the situation. Imagine watching a horror movie and anticipating the feeling of being scared out of your skin. If your life were a horror movie, you would constantly be on edge—anxious and just waiting to be scared. Life would be a constant adrenaline rush. How long do you think you could last like that?? Emily’s life is like a never-ending horror movie. Tiny tumors in and on her adrenal glands cause the glands to overproduce epinephrine, norepinephrine and cortisol—hormones that combat stress both short and long term. As a result, Emily’s body, left untreated, prepares itself for the flight or fight reaction twenty-four seven.
