1. Objective: How do the different endocrine glands maintain homeostasis through hormones?

2.  Take the page and divide it into 6 equal boxes  Number the boxes Notes: Endocrine System12 34 56

3.  Made up of various glands that maintain homeostasis through the use of hormones

4.  Hormones = chemicals that are released and travel the blood stream to affect the activities of cells  Very specific and only affect certain cells!

5.  Both maintain homeostasis in the body  The NS uses chemicals called neurotransmitters while endocrine system uses chemicals called hormones.

6.  Negative feedback = a “stimulus” causes an opposite “reaction” in order to maintain homeostasis  Ex: Eating a candy bar raises blood sugar levels and my pancreas makes insulin to lower it. In this example what's the stimulus?

7.  Pituitary Gland = “master gland”  Pineal Gland = “sleep gland”  Thyroid Gland = “metabolism gland”  Pancreas = “sugar level”  Adrenal Glands = “fight or flight”

8. What is the question to the answer? (I’ve given you an answer you’re to write a question for it) Endocrine System
