Brain Power
CONTROL CENTER
The brain is the most complicated part of the body. It takes up 2% of our body weight but uses 20% of our energy supply it receives information and sends out message to control our behaviour and movements. It allows us to think, learn and remember. The brain floats in liquid and the hard skull protects it. The adult brain weighs around 1.4 kilograms -- but a six year old's brain is already adult sized
PARTS OF THE BRAI
Your brain is divided into three main parts.
The smallest part controls breathing and digestion.
The middle part controls
Movements.
The biggest part controls
Intelligence, the senses and memory.
Different sections of this part are responsible for different things.
These include smell, sight, touch, music and language.
Scientists study brains while people are doing activities,
Such as talking. They can see
which part of the brain is used
MESSENGER
There are billions of cells inside
the brain
There are two main types
Nerve cells:
There are about 100 billion nerve cells in the brain. They are responsible for everything we do by sending electrical and chemical signals. These signals can travel as fast as 90 metres a second.
Supporting cells:
These cells protect the nerve cells and keep the brain healthy.
LEFT AND RIGHT
The brain is also divided into two
halves
The left side controls the right side of the body.
In most people this side is used for creative activities.
The right side controls the left side of the body. In most people this side is used for logical activities such as maths
