You never heard of me but I am the single most important group of cells in your body - on duty 24 hours a day even though most of the time you are not aware of what I am doing. My chief responsibility is maintaining equilibrium inside you. I inform other regions of the brain and body that their services are required. As a result of my constant monitoring, you knows when you are hungry, thirsty, hot or cold and how to react to anger or fear. In one way or another, I take part in just about everything you do. I am not bright like other parts of your brain. Thinking is not my business. I suppose you could call me the central switchboard of your body, a sort of coordinator for much of your nervous system and for your pituitary gland which is often called the master gland because of its influence on metabolism, growth and secondary sex characteristics, as well as other functions of the hormone system.
