Guidelines:
Whoever has the ball is speaking
If you do not have the ball, you are tracking the speaker and NOT speaking
DON’T DROP IT 

11. Nervous System Lab: Sensation, Thought, and Response

12. Whiteboard check: Sensory, Inter, or Motor?
TYPES OF NEURONS. Fill in the blanks with sensory neuron, interneuron, or motor neuron:
1) __________________ send information from sense organs to the central nervous system, 2) _____________________ process the information, and 3) ______________ send information to muscles or glands for an action response.

13. Which sequence of neurons shows the correct pathway of sensation, thought, and response?
sensory neurons  motor neurons  interneurons.
Sensory neurons  interneurons  motor neurons
Motor neurons  sensory neurons  interneurons
Interneurons  sensory neurons  motor neurons.

14. Which of the following is NOT an example of a sensory neuron?
Pressure sensor in skin
Taste buds
eye
brain

15. Your brain sends a message to your quadriceps muscle to kick the soccer ball. The ____________________ is responsible for causing the movement in your muscle:
Sensory neuron
Motor neuron
Interneuron in the brain
Interneuron in the spinal cord

16. What happens when you touch a hot stove?
REFLEX

17. Reflex Arcs

18. Reflex Arcs
Watch the video and discuss what happened with your neighbor.

19. Reacting to Changes
You need to keep the conditions inside your body constant (maintain homeostasis).
You need to detect a change in the environment (a stimulus) and react to the change (a response) in a way that maintains homeostasis. When you do this without thinking, it is called a reflex.

20. The Knee-Jerk Response
What is the stimulus?
The hammer hits the tendon.
What is the response?
The muscle contracts, causing
the foot to jerk upward.

21. Other Reflexes Stimulus Response The aroma of your favorite food
Salivation
A nasty odor
Nausea
A bright light shining in your eye
Pupils get smaller
An insect flying towards your eye
Blinking

25. Whiteboards: Label the Reflex Arc Diagram
Word Bank:
Stimulus
Sensory neuron

Response E

26. How does the nervous system respond when you touch a hot stove?

27. Nervous System and Reflexes Mastery Questions

28. Exit Slip – p. 21L
Answer the questions in your notebook on p 21L. Do NOT copy the questions.
How is the nervous system related to smell, taste, touch, hearing, and sight? Explain how the nervous system keeps organisms alive. 
Compare the three types of neurons to parts of a computer. Explain each connection you have made.
Ex. Sensory neurons are like the keyboard or mouse because they sense changes.
