1. Warm up:
Get out a piece of paper and answer the following question: How do cells communicate in your body? Give three examples.

2. REVIEW QUESTIONS

4. REVIEW QUESTIONS

5. KEY CONCEPT The nervous system and the endocrine system provide the means by which organ systems communicate.

6. What is a stimulus?

7. The body’s communication systems help maintain homeostasis.
A stimulus causes a response.
Responses can be chemical, cellular, or behavioral.
The nervous and endocrine systems respond to stimuli.

8. How do the nervous and endocrine systems communicate?

9. What do the nervous and endocrine systems control?

10. The nervous system controls thoughts, movement, and emotion.
The endocrine system controls growth, development, and digestion.

11. Which system do you think communicates quicker?

12. The nervous and endocrine systems have different methods and rates of communication.
The nervous system works very quickly, using chemical and electrical signals.
spinal chord
nerves

13. How does the endocrine system communicate?

14. The endocrine system works more slowly.
only chemical signals (usually hormones)
The bloodstream delivers hormones to target organs
target cell
hormone
bloodstream
receptor
not a target cell

15. List as many hormones as you can below: How do they work?

16. List at least 4 jobs you can think of that nerves have.

17. Video:

18. Lets compare and contrast the nervous and endocrine systems together.

19. How do they communicate? Could you live with one and not the other?
Next:
Use the chart we just drew to compare and contrast the nervous and endocrine systems in your own words.
How are they different?
How are they the same?
How do they communicate?
Could you live with one and not the other?
Write at least two paragraphs comparing and contrasting these two systems and turn it in when you are done.
