2.  Compare the endocrine system and nervous system. Do they both use feedback systems? Do they both maintain homeostasis? Do they both use signal molecules that bind to a receptor?

3.  What is a pheromone?

4.  Describe the action of a protein (peptide) hormone.

5.  Describe the action of a steroid hormone.

6.  What other function does the pancreas have besides endocrine? What is it’s exocrine function?

7.  Be able to determine the difference between examples illustrating negative feedback and positive feedback.

8.  What does tropic mean? How many different organs are involved in Thyroid Hormones being released?
