Nervous System

The body system responsible for sending messages and signals throughout the body.

Nervous System

Organ(s): Brain, spinal cord, etc.

Functions(s): Transmits messages and coordinates body functions

Interesting Facts:

• Central Nervous System (CNS) processes information.

• Peripheral Nervous System (PNS) receives information and relays commands.

• Electrical and chemical messages move up tp 270 mph.

Specialized Cells:

• How does the shape of the nerve cell help it communicate messages?

​Neuron - Nerve Cell

Your nervous system is split into 2 major parts

• Central Nervous System

• Peripheral Nervous System

Parts of the Nervous System

Your nervous system is made up of your brain, spinal cord, and nerves.

Brain Cells (Neurons)

Neurons are the cells that make up most of your brain and nervous system. They have a very special job, and are designed to work in a very specific way. Each Neuron has lots of little arms (dendrites) that receive messages from other neurons' axon and nerve endings (tail). This allows the nerve cells to quickly pass signals throughout your body.

Fight or Flight?

Have your ever been really scared? Think of walking through a haunted house... Did you feel anxious? Scared? Was your heart beating faster than normal? Were you more aware of things happening around you? This is your nervous system in "fight or flight" mode.

Fight or Flight

When you're scared, your nervous system goes into its' Fight or flight mode, which is designed to prepare your body to either fight, or run (flight). Your heart rate increases, you might start sweating, you're more aware of things happening around you, you feel anxious, and your mind starts racing. Your body is preparing itself for a fight or a flight.

They ALL work TOGETHER!!!

All of your body systems work together and are interconnected! Your nervous system is in charge, and helps tell all of the other systems what to do!

Respiratory System

Organs: Nose, lungs, diaphragm, etc.

Function: Moves oxygen-rich air in and carbon dioxide-rich air out

Interesting Facts:

• Your lungs are only sacs that inflate/deflate when your diaphragm muscle moves.

• The inside of your lungs look like sponge with many cells and air pockets for gas exchange.
