1. Nervous System

2. The nervous system allows for communication between different parts of the body.
This helps us to regulate our bodies.

3. Made up of? Divided into two parts: 1. Central Nervous System
Includes brain and spinal cord

4. Made up of? 2. Peripheral Nervous System
The rest of your nerves (neurons) found throughout your body

5. How does it work? It’s all about action and senses
What happens inside & outside of your body
Do not copy

6. How does it work? Nerves react to a stimulus
(A change in the environment that you respond to)

7. How does it work?
Nervous System regulates your body with electrochemical impulses (signals carried by the nerves)
Draw picture here

8. Sensory vs. Motor Neurons
Sensory neurons fire in response to stimuli in the environment
Motor neurons cause muscles to react

9. Basically…
Your five senses receive a stimulus in their sensory neurons
The sensory neurons send an impulse to your brain
Your brain responds and send an impulse to the motor neurons
Motor neurons react
