Endocrine system - endocrine v nervous system

Lesson 4 - Endocrine system v the nervous system

1. The Endocrine System vs. The Nervous System

2. 2 Net work of glands that secrete chemicals called hormones to help your body respond to stimuli . Chemical Messenger: hormones Slow acting hormones made far away from target cells travel through blood Long lasting changes to the body Overview of the Endocrine System

3. This communication system controls and coordinates functions throughout the body and responds to internal and external stimul i . Chemical Messenger: neurotransmitters Fast electrical action potentials Signals travel along neurons via neurotransmitters Short-acting changes to the body Overview of the Nervous System

4. In your notebook draw a Venn diagram to compare and contrast the similarities and differences of the endocrine system and the nervous system. Review

5. So basically… The Nervous S ystem is a sprinter. The Endocrine System is a long distance runner .

6. Team up with your table group When I read the example, guess within your table group if the nervous system or the endocrine system is regulating the response. You must be able to explain your reasoning! Slap your table when you have the correct answer and explanation. There is a prize for the winning team! Game Time!

7. Finally …Exit Slip Let’s go back to your Venn Diagrams, compare the one in your notes to the one on the next slide and make changes accordingly

8. Glands vs. Nerves C hemical messengers Feedback loops Regulate physiological activities to maintain homeostasis Respond to stimuli
