Endocrine system - endocrine v nervous system

  1. 1. The Endocrine System vs. The Nervous System
  2. 2. 2 • Network 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. 3. • This communication system controls and coordinates functions throughout the body and responds to internal and external stimuli. • 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. 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. 5. So basically… The Nervous System is a sprinter. The Endocrine System is a long distance runner.
  6. 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. 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. 8. Glands vs. Nerves Endocrine System • System of glands • Hormones are transmitted through blood stream • Slow, but chemical response lasts longer Nervous System • Signals travel along neurons via neurotransmitters • Fast electrical action potentials • Short-acting changes to the body • Chemical messengers • Feedback loops • Regulate physiological activities to maintain homeostasis • Respond to stimuli
