1. The Nervous System

2. Video Anticipation Statements
Pain happens only in your head.
Anyone can be hypnotized.
Nerves don’t actually touch each other.
Not feeling pain is a good thing.
Most people can get along just fine with out senses.
You can control your nervous system.

3. Challenge ? Are you more right-brained or more left-brained?
Take the Test
Describe/diagram your results below.

4. Connection
Why is it important that reflexes occur without thought?

5. Vocabulary Central nervous system Peripheral nervous system Impulse
reflex

7. Objectives Notes Describe the peripheral nervous system
(Copy & label diagram of neuron pg. 589)
Function of system –
> Neurons transmit information by -
> sensory neurons –
> motor neurons -
Describe the central nervous system (Copy & label diagram of brain pg. 592)
> Brain-
> cerebrum-
> cerebellum-
> medulla-
> Spinal Cord
Explain the difference between neurons and nerves

8. Objectives Notes Describe the peripheral nervous system
(Copy & label diagram of neuron pg. 589)
Function of system – Collects, sends information to and responds to information from the central nervous systems
> Neurons transmit information by – special cells that transfer messages (impulses)around the body by electrical energy
> sensory neurons –collect information and send to CNS
> motor neurons – respond (move) to information sent from CNS
Describe the central nervous system (Copy & label diagram of brain pg. 592)
Function of system – Processes information sent by the PNS
> Brain- largest organ in nervous system –mission control
> cerebrum- stores memories, controls voluntary movement, detects touch, light, sound, sight, odors, taste; judgment
> cerebellum- controls body position and movement
> medulla- controls most involuntary processes; life processes
> Spinal Cord – connects PNS with brain – relay; initiates reflexes before signal can travel to brain -
Explain the difference between neurons and nerves
Neurons are cells that transfer electrical impulses through out the body and nerves are the axon parts of the neurons bundled together with blood and connective tissue
