What is a Neuron?

​

Long cells in the brain that can communicate with each other.

​

The branches receive and send out information in specific directions!

​

Scientists believe that there are around 86 billion neurons in the brain!

(cell body)

Dendrites

Building a Neuron: Step 1�Building the dendrites and terminals �

​

  • On one piece of paper, trace your left hand with orange and draw a circle in the center with blue
  • Color this hand in with orange
  • On this same sheet of paper, trace out just the fingers of your right hand in red and color it in
  • Cut these hands out and paste them onto the tube

Building a Neuron: Step 2

Building the Axon �

​

  • On a new second sheet of paper cut 2-3 strips of paper out and color them green
  • Glue these onto the tube

Why is the Neuron so important?

​

Neurons build the brain entirely and need to be taken care of!

​

Damages to large amounts of neurons -> Severe mental illnesses
