Question

After reading about the nervous and endocrine systems, explain how people can become addicted to various substances and even activities. You must discuss the role of both systems in your answer.

Answer 1

The Nervous system releases dopamine and other reward chemicals in response to stimuli. Some such stimuli are addictive substances such as nicotine. When this happens the endocrine system sends bodily messages to relax. Having too much of an artificial substance provoking reward chemicals in your brain results in you not responding or producing enough on your own. Thus how addiction begins to occur. Hope this helps!
