1. Introduction to the Brain and Nervous
System by Jennifer Kenny
Answer both questions on the back in complete sentences

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

helps you move, feel, see, hear, taste, smell, learn, form memories and emotion

1.
Brain
2.
Spinal Cord
3.
Nerves

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

Why is the brain like a computer?

Just like the Skeletal System, the Nervous
System is divided into 2 parts as well
Central / Autonomic
&
Peripheral

* 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.

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 Cerebellum
3. 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.

• TextBook 107B, answer 1-3. Write Questions!
• The Nervous System
• The Brain

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?

19 – 18 = A
17 – 16 = B
15 = C
14 = D
Below 13 = F

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.

Central Nervous System
- what does that mean?
- What does it do?
What parts are in it?
Brain > function and location of each part

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

Central / Autonomic = Brain & Spinal Cord
Function = controls all of the voluntary and involuntary movement in your body

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?

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 Skin
Eye
Nerves
Tongue

• To connect the central nervous system to the limbs (arms & legs) and organs all around the body

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

Motor neurons – work with muscles to make movement possible
Sensory Neurons – bring messages from senses to our brain

- human body is made of billions of neurons
Neurons connect to other neurons to make pathways or tracts for messages to travel down

Myelin
Dendrites
Axon Cell Body

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

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.

The organs in your body that allow you to sense
Eyes
Ears
Nose
Tongue
Skin

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.
