ABSTRACT
In this chapter we consider homeostasis as an example of how the CNS, ANS and endocrine system work together. The term homeostasis refers to the maintenance of a relatively stable state within our bodies. In the first part of the chapter we take a closer look at exactly what this means. The rest of the chapter details three major homeostatic mechanisms, namely, the regulation of our nutritional content (eating), the regulation of our water content (drinking), and the regulation of our body heat (temperature regulation). As you work through the chapter you will see that all three mechanisms are kept in balance by a combination of hormonal and ANS activity, all of which is coordinated by central brain processes.
