The Nervous System

Think about how a restaurant serves a meal to a customer. Does one person enable the entire restaurant to function, or does every employee have a job that contributes to the service of a customer? It takes many restaurant employees to serve a meal: greeters, servers, chefs, bussers, etc. There is also a manager to help make sure that customers are satisfied and that all employees have what they need in order to do their jobs properly.

Imagine that your body is a restaurant. This restaurant also has a very important manager to help with its functions: the nervous system. The nervous system has nerve cells that tell every other system, organ, and tissue in your body what to do.
