Serotonin acts as a bridge between nerve cells.
Serotonin is stored inside nerve cells. When a nerve cell starts to send a message, it releases this "stored" serotonin into the space the message must cross to get to the next nerve cell. Once the serotonin is outside of the nerve cell, it is "free" to work. Because it helps carry the message from one nerve cell to another, serotonin is called a neurotransmitter. Once the message has crossed successfully to the next nerve, the serotonin goes back into the nerve cell where it is stored until needed again.
Serotonin is one of the many natural chemicals stored in the nerves. Brain nerve cells need serotonin to send messages [electrical impulses] to each other so that you can walk, eat, and live.
