Unit A Nervous and Endocrine Systems


Concept Organizer

The following concept organizer illustrates the relationships between the nervous system and the endocrine system and how they establish homeostasis. System health results when these relationships are balanced. The concepts at the top of the chart identify the main questions to be considered in this unit and indicate the importance of applications of technologies throughout the unit. You may wish to revisit this concept organizer as you work through the unit as well as use it as a study guide.


The Nervous System

In this section, you will explore both the conscious and unconscious communication of your body. You will examine the structure, organization, and function of the nervous system, and how it maintains homeostasis. You will examine also what occurs when communications are stopped or broken. You will research how imbalances and disorders cause the nervous system not to function well and how medical technologies can be applied to correct these situations.

Specifically, you will apply your knowledge to answer the following question:

  • How does the nervous system communicate with the body?

The Endocrine System

In the second section of this unit, you will investigate how hormones produced by the endocrine system communicate with parts of your body to maintain homeostasis. You will examine the endocrine glands and what happens when these glands produce too little or too much of a hormone. You will research how medical technologies can be applied to correct these situations.

You will be asked to apply your knowledge to answer the following question:
