        other arms -- called dendrites
These cells in our cortex are a grey color, so together they form our "grey matter". This part of the brain stores pieces of information. But the cells in the grey matter need to communicate with each other. This is where "white matter" comes in. The white matter is the inner part of the brain. Each brain cell has long extended arms. The cell sends information down one arm called an axon. Think of it like a telephone sending information down a wire. Every cell has one of these axons. The cell also has other arms -- called dendrites. These are lines for receiving information.
