In the Big Picture you were introduced to Emily and her struggle with familial multiple endocrine neoplasia type 1 (FMEN1) disorder. You might think that you experience stress when you are cramming for exams or are worried about a friend. You may get a headache, your heart may race, or you may have a sleepless night. Your endocrine system reacts to the stress by secreting many hormones that help you cope with the stress. When the exam or the crisis has passed, you seem to calm down because your endocrine system has returned the level of “stress” hormones to normal. In Emily’s case, her body experiences constant stress with no chance of relief. How might Emily’s endocrine system be different from yours? You both have the same organs, but it is obvious something is not working or communicating properly in Emily’s case.
In order to explore these concepts, you will investigate the following focusing question:
- How is the endocrine system organized, and how do its parts communicate with each other and with various parts of the body?
