Warm Up
1. Introduction to the Brain and Nervous System by Jennifer Kenny
Answer both questions on the back in complete sentences
Nervous Systems
The Nervous System
Function -
CARRIES MESSAGES FROM THE BRAIN TO PARTS OF YOUR BODY TELLING THEM WHAT TO DO
MOVES INFORMATION THROUGHOUT YOUR BODY
The nervous system also allows you to react to a stimulus.
A stimulus is a change in the environment.
Example: A hot stove
Or… tripping over a rock
Importance
helps you move, feel, see, hear, taste, smell, learn, form memories and emotion
Parts of the Nervous System
1. Brain
2. Spinal Cord
3. Nerves
Parts of the Nervous System
Brain = Computer
Spinal Cord = Central Cable that carries messages to and from computer
Nerves = Keyboard, Mouse connect to spinal cord, carry messages to every part and also back to the brain
Stop and Think
Why is the brain like a computer?
Kids Health Video
Remember AXIAL and APPENDICULAR
Skeleton?Just like the Skeletal System, the Nervous
System is divided into 2 parts as well
Central / Autonomic
&
Peripheral
Central/Autonomic Nervous System
* Controls all of the body’s activities and movement.
* The Central/Autonomic Nervous System is made of two
main organs.1. The brain
2. The spinal cord
* Function: carries messages between brain and nerves around body
•Importance:
connects the brain to the rest of the nervous system, without it brain couldn’t get messages to body
* The vertebrae are the many bones that protect the nerves in
the spinal cord.
Stop and Think
Why is our spinal cord inside our vertebrae?
* The brain controls/manages everything in the body.
•The brain is made of more than 10 billion nerves and weighs about 3 pounds* The brain is divided into three parts and is protected by the skull.
* The Brain has three main parts…
1. The Cerebrum
2. The Cerebellum3. The Brain Stem
* Largest part of the brain. The top half
The cerebrum controls 1.thinking & emotions
2. memory
3. speaking.
4. movement
* Below and to the back of the cerebrum.
controls 1. balance.
2. posture.
* The Brain Stem connects the brain to the spinal cord.
* The nerves in the brain stem control all involuntary movements like your heartbeat, breathing, and blood pressure.

Brain Independent Practice / HW
• TextBook 107B, answer 1-3. Write Questions!
• The Nervous System
• The Brain
Exit
1. What role does the brain play in the nervous system?
2. What do you think life would be like if your spinal cord did not connect to the rest of your body?
Quiz Return
19 – 18 = A
17 – 16 = B
15 = C
14 = D
Below 13 = F
Warm Up – put hw on desk to be checked
Answer the questions below. 2 and 3 must be answered in complete sentences
1. The cerebrum controls
a. Thinking
b. Speaking
c. Movement
d. All of the above
2. What 2 organs make up the central nervous system?
3. Why is the vertebrae important?
2. What 2 organs make up the central nervous system?
Brain
Spinal Cord
3. Why is the vertebrae important?
The vertebrae protects the spinal cord.
Goals
Central Nervous System
- what does that mean?
- What does it do?
- What parts are in it?
Brain > function and location of each part
Parts of Brain & Functions
Cerebrum > thinking, emotion, memory, speaking, movement *SENSES
- sight, taste, touch, hear, smell
Cerebellum > balance and posture
Brain Stem > all involuntary movements
- Heart beat, heart rate, breathing, blood pressure

2 “parts” of the nervous system
Central / Autonomic = Brain & Spinal Cord
Function = controls all of the voluntary and involuntary movement in your body
Brain & Spinal Cord Activities
1. The Nervous System – Brain handout (cross out #7)
2. What are the Parts of the Brain? handout
3. The Brain Poster
4. Your Nervous System – Ready for Action Article and Questions
5. Brain Origami
* After finishing an activity you must check for correctness before moving on
• If answer are wrong, try again
• If correct move on to next assignment
Exit Ticket
1. You are memorizing vocab words for a quiz, which part of the brain is working for you to memorize?
2. Your heart is beating, which part of the brain controls that?
Warm Up
Put yesterday’s HW on desk
Copy the sentences and fill in the blanks.
1. The 3 parts of the brain are the ___________, __________ and _________.
2. Balance and posture are controlled by the _____
3. The Central Nervous system is made up of the ____________ and _________
•Made up of the nerves/neurons that come from the brain and spinal
cord
* and the sense organs.
Ear
EyeSkin
Nerves
Tongue
Function
• To connect the central nervous system to the limbs (arms & legs) and organs all around the body
Neuron
What is it?
A nerve cell, it is one of 2 main types of cells found in the nervous system.
Function
Carry messages to and from the brain through the spinal cord to every part of the body
Types of Neurons
Motor neurons – work with muscles to make movement possible
Sensory Neurons – bring messages from senses to our brain
Other info
- human body is made of billions of neurons
- Neurons connect to other neurons to make pathways or tracts for messages to travel down
What does a neuron look like?
Dendrites
Axon Cell Body
Myelin
Functions of Neuron Parts
Dendrite = part of the neuron that receives messages from other neurons
Axon = receives messages from the cell body and send the messages to dendrites of other neurons
Cell Body = Controls whether a message is sent to the axon
Myelin = fatty substance that covers/protects the axon
Messages are sent through Neuron chains
Synapse = gap between the axon of one cell and the dendrite of another
Dendrite Cell Body Axon
Sense organs carry
messages about the
environment to the central
nervous system.
What are sense organs?
The organs in your body that allow you to sense
- Eyes
- Ears
- Nose
- Tongue
- Skin
Vision is your ability to see.
*Optic nerves in the eye carry the image from the back of the eye to the brain
When a sound is made, the air around the sound vibrates.
vibrations travel inside head and turn into signals.
*Vestibular nerves in ear send signals to the brain and a message telling us what the sound means is
made
*The liquid in your inner ear works with the brain to control your
balance.All of your movements are
controlled by balance and muscles.
The sense of touch is located in the skin.
The sensory receptor nerves in the skin allow us to feel
texture, pressure, heat, cold, and pain.
*Sense Receptors in the nose control your sense of smell.
The nose is able to smell 80 different kinds of smells.
Scientists don’t understand anything about how our sense of
smell works !!
Your sense of taste comes from the taste buds in the tongue.
*Taste buds (small lumps of sensing tissue) are the parts on the tongue
that allow us to taste.The four kinds of taste buds are
sweet, sour, bitter, and salty.
What type of neuron deals with the senses?
Sensory Neurons
Exit.
