Module 2—The Endocrine System
Lesson 6—Bringing It Together
Get Focused
In the previous module you learned how the nervous system responds to environmental stimuli by using neural pathways to produce very rapid and precise responses. The endocrine system responds to stimuli by using chemical messengers in the blood to control metabolic processes in the body. These responses are much slower than the responses of the nervous system, with the exception of the responses controlled by epinephrine. Your body is in balance (homeostasis) because your nervous system responds to immediate stimuli or crises while your hormonal system maintains long-term stability. A major part of this balance is missing from Emily’s life. Because of the tumours that can grow on any of her glands, her endocrine system does not respond appropriately. The balance of Emily’s endocrine system is jeopardized, impacting her health and life. The decisions you make, and the overall health of your nervous and endocrine systems, can impact your life now and in the long run.
This lesson will allow you to explore how the nervous and endocrine systems complement and communicate with each other to maintain homeostasis and well-being.
In this lesson you will investigate the following focusing question:
- How are the nervous and endocrine systems interdependent and how are they different?
Module 2: Lesson 6 Assignment
Download a copy of the Module 2: Lesson 6 Assignment to your computer now. You will receive further instructions about how to complete this assignment later in the lesson.
You must decide what to do with the questions that are not marked by the teacher.
Remember that these questions provide you with the practice and feedback that you need to successfully complete this course. You should respond to all of the questions and place those answers in your course folder.
Because this is the last lesson in this module, you will also need to submit the Module Assessment, which is a written-response question. The question is based on data from a case study involving one of the hormones that you have studied in this module. When you have completed the module, go to the Module Summary and Assessment page for information about the written-response question and the evaluation criteria.
While you are completing this lesson, there will be many opportunities for you to acquire, understand, and practise the concepts that are presented to you. As you complete these activities, as well as your summary notes, you will file everything in your course folder to reference when you are preparing for exams.
Remember you also have the option of trying additional questions from the textbook for further practice. Consult with your teacher for the answers to these questions. The Key will also provide you with many Diploma Exam-style multiple-choice, numerical-response, and written-response questions that will be an excellent review of the module. Practising your responses to these types of questions is good preparation for the Diploma Exam.
