How the Brain Works<br />
There are 100 billion nerve cells in your brain. On each nerve cell are<br />
two branches:<br />
Dendrites, which receive incoming messages from other cells<br />
in the form of an electrical impulse.<br />
Axons, which carry outgoing signals to other cells.<br />
Interconnected, they provide super-fast communication, allowing the<br />
brain to send messages from one side to the other, which lets you<br />
move and make decisions. This is done by a chemical that is shot from<br />
the axon across a gap (synapse) where it triggers another cell to send<br />
a message.<br />
An injury to your brain can destroy or damage these nerve cells, which<br />
means that some messages will not get through or may get scrambled<br />
along the way.<br />
