It regulates all of your body functions and activities.

4. The Nervous System- is composed of your Brain, Spinal Cord, Nerves, and Sensory Organs.
(eyes, ears, and taste buds of the tongue)

5. Function
Controls voluntary activities- such as walking and talking, and controls involuntary activities such as heart beat and digestion
It also allows you to: see, hear, smell, taste, and detect pain and pressure

6. How it Works
The nervous system works by sending electrical messages called nerve impulses to and from various parts of the body.

7. Parts of The Nervous System
The Brain- a mass of nervous tissue located inside the skull. There are three main parts of the brain and they all work together.

8. 1. The Cerebrum- The largest and most complex part of the brain.
- coordinates the body systems
- controls the senses; taste, smell, touch, sight, and hearing
-also controls; emotions, voluntary muscle movement
-consciousness
-learning and memory

9. 2. The Cerebellum- the second largest part
-controls coordination, balance and posture
3. The Brainstem- connects to the spinal cord (the base of the brain)
-controls life support functions; heart rate, blood pressure, and breathing

10. The Central Nervous System
(CNS) includes the brain and the spinal cord

11. The Spinal Cord- is a bundle of nervous tissue about one and a half feet long, protected by our backbone or spine
Function of the Spinal Cord- relay impulses between the brain and the parts of the body

12. Sensory neurons- carry messages to the brain
Two types of neurons
Sensory neurons- carry messages to the brain
Motor neurons- carry responses to the muscles. (actions)

13. Nerve damage is usually permanent.
If a nerve is damaged or destroyed it cannot be replaced.
