Our communication system in the body known as the endocrine system. And the endocrine system creates a special type of chemical known as a hormone. Now, the hormone is released by the cell into the bloodstream or into the lymph system and the hormone, unlike the neurotransmitter actually travels over a very long distance throughout the entire body before it actually affects the target cell. Now, neurotransmitters are very specific to the type of cell that they bind to but hormones are not that specific. That means they can bind to many different types of cells and some of these cells can be affected in an activating manner whilst other cells can basically be inhibited by that same hormone. So unlike neurotransmitters which basically acts over very short distances and act very quickly and are short lived our hormones travel over very long distances.
