The Nervous System
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.
Challenge ?• Are you more right-brained or more
left-brained? • Take the Test • Describe/diagram your results below.
Connection• Why is it important
that reflexes occur without thought?
Vocabulary
• Central nervous system• Peripheral nervous system• Impulse• reflex
Resources
• Video –– Human Body: Pushing the Limits: Sensation
(open)– Human Body: Pushing the Limits: Brain
Power(close) if time allows• Be Nervy – Simulate nerve impulses• Guided Notes • Complete Objective Notes
Objectives NotesDescribe 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)
Function of system –
> Brain- > cerebrum- > cerebellum- > medulla-
> Spinal Cord
Explain the difference between neurons and nerves
Describe the peripheral nervous system
– 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 to information sent from CNS
Describe the central nervous system
• 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
