By: Mr. Hunter

2. What makes up your nervous system?

3. Central Nervous System
Brain and spinal cord
Responds to all messages coming from the peripheral nervous system
Acts as a _____ center

4. CNS

5. Peripheral Nervous System
Uses nerves to carry information between your body and the ___

6. PNS

7. Neurons
A nerve cell that is specialized to transfer messages in the form of fast-moving energy
Dendrites: short branched sections of the cell that receive information
Axons: extensions of a neuron that carry information away from the cell

10. 2 types of Neurons
_____ : gather information of what is happening in and around your body
_____: send impulses from the brain and spinal cord to other systems

11. Sensory Neurons
Touch
Taste
Smell
Sight
Sounds

12. Motor Neurons
Muscles
Glands

13. The Brain
As you might imagine, larger animals have larger brains. However, this does not mean that animals with larger brains are smarter than animals with smaller brains. For example, a larger brain is necessary to control larger muscles in larger animals and a larger brain is necessary to process more sensory information from the skin in larger animals - this has nothing to do with intelligence.
