4. How does it work?
• The brain is made up of cells called neurons.
• The human brain may contain up to 100 billion neurons of
different kinds.
• Every second, a single neuron will send as many as 1,000
signals.
• The following are the three different parts of the brain:
a. Cerebrum

• Motor nerves relay signals from your brain to your muscles,
telling you how to respond
8. Fascinating Facts
