The function of the nervous system is to send and
receive messages that control your body’s activities.
Such as walking, breathing, and thinking.
The nervous system has two different major parts.
The two parts are the Central Nervous System (CNS) and
the Peripheral Nervous System (PNS).
The nervous system is a highway, messages travel
along this highway passing information to and from the
two systems.

The nervous system is made of:
The brain
The spinal cord
The nerves

The Nervous System has two major parts:
Central Nervous System
Peripheral Nervous System
The nervous system is a highway, messages
travel along this highway passing
information to and from the two systems.
![Page 5: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves. The job is to send information gathered by the body's sensory](https://reader034.vdocuments.net/reader034/viewer/2022051815/603c6e3f8407946b157a6bb5/html5/thumbnails/5.jpg)
The brain and spinal cord make up the
central nervous system. The Central Nervous
System is the processing center of the nervous
system, it is like a big computer.
![Page 6: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves. The job is to send information gathered by the body's sensory](https://reader034.vdocuments.net/reader034/viewer/2022051815/603c6e3f8407946b157a6bb5/html5/thumbnails/6.jpg)
Is made up of many nerves.
The job is to send information gathered by the
body's sensory receptors to the central nervous
system as quickly as possible.

Nerves carry
messages about
the environment
to the central
nervous system.

1. Stimuli from the sense organs change to electrical
signals.
2. The nerves carry these electrical signals to the brain
and spinal cord.
3. The brain decides what the stimulus is and how to
respond to it.
4. Nerves then carry the response or what to do
message away from the brain.
The message is delivered to the part of the body
that will respond to the stimuli.

Peripheral Nervous System:
Is made up of many nerves.
The job is to send information gathered by the body's
sensory receptors to the central nervous system as
quickly as possible.
Central Nervous System:
Is made up of the brain and spinal cord.
The Central Nervous System is the processing center
of the nervous system, it is like a big computer.

controls the body functions by receiving and
sending out messages to tell it what to do.

bundle of nerves that connects your brain to your
body.
Sends messages to the brain
It is found down the center of your back and runs
from the base of your brain down to your tailbone.
![Page 18: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves. The job is to send information gathered by the body's sensory](https://reader034.vdocuments.net/reader034/viewer/2022051815/603c6e3f8407946b157a6bb5/html5/thumbnails/18.jpg)
Your spinal cord is a bundle of nerves that connect your
brain to your body.
It can be found down the center of your back.
It runs from the base of your brain down to your tailbone.
![Page 19: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves. The job is to send information gathered by the body's sensory](https://reader034.vdocuments.net/reader034/viewer/2022051815/603c6e3f8407946b157a6bb5/html5/thumbnails/19.jpg)
• The spinal cord is protected by 33 bones called
vertebrae. Branching out from your spinal cord are thirty-
one pairs of nerves.
• There are times when the brain does not have time to
decide how to respond. In emergencies like this, the
spinal cord sends the response even before the brain
gets the message. An emergency response to stimuli is
called a reflex.

Nerve Cells:
• Nerve cells make up the nerves inside the
nervous system. Each one is called a neuron.
• Nerves are tiny fibers that send impulses along
your body.
• Nerve cells carry electrical signals to the brain
and spinal cord.
![Page 21: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves.

• The fibers are covered with a substance called myelin.
Myelin helps the messages go quickly through the
neurons.
• The job of the neuron is to carry messages. Nerves carry
messages in one direction only.
• Some nerves carry messages to the brain and spinal
cord. Others carry the messages away from the brain
and spinal cord.

Your brain has 3 main parts:
Cerebrum, Cerebellum, and Medulla

Cerebrum:
This is the largest part of your brain, making
up 85% of the brain’s weight. It controls
certain voluntary muscles. These are
muscles you think about moving.
Running, talking on a telephone and using a
computer are examples of voluntary muscle
movements. This part of the brain is also in
control of our senses, thoughts, memory and
learning
![Page 30: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves.

Cerebrum:
Also, controls input from your senses, imagination,
learning, and memory.
There are two halves of the cerebrum. They are usually
called the right or left side of your brain. Scientists know
that the right side of the brain controls the left side of
your body and the left side of the brain controls the
right side of your body.
![Page 31: Day 1: Nervous System Central Nervous System Peripheral ... · Peripheral Nervous System: Is made up of many nerves.

Cerebrum:
They also think that the right side of the brain controls
things like music, color, drawing and shapes and the
left side of the brain controls math, problem solving
and speech.
You may have heard of someone being described as
“right-brained”. This is usually used to describe
someone who is creative. If someone is described as
“left-brained”, they are usually good at math or solving
difficult problems

Cerebellum :
- This is located at the back of the brain.
- The cerebellum is much smaller than the
cerebrum. It is roughly 1/8 of the size.
- The cerebellum receives controls how
the muscles work together. It controls
balance, movement, coordination.

Medulla:
• The medulla is also known as your
BRAIN STEM.
• The brain stem is where your brain
connects to your spinal cord.
• The medulla or brain stem is in charge
of involuntary movements.

Medulla:
• Involuntary means that they happen
without having to think about it.
• Examples of involuntary movements
that the brain stem is in charge of are
breathing, swallowing, heartbeat and
food digestion.

You learned:
• Your brain is like a central control station for your
body.
• There are three main parts to your brain; cerebrum,
cerebellum and medulla.
• The cerebrum controls input from your senses,
movement, learning and memory.
• The cerebellum controls balance, movement and
coordination.
• The medulla or brain stem controls involuntary
movements such as breathing, swallowing and
heartbeat.
