What are cell receptor sites?

William B. Salt II., MD
Gastroenterology
Every cell in your body has thousands of locations on its surface that serve as "mini" sense organs, called receptor sites. These receptor sites are actually proteins that are on the surface of each cell. They act as little receivers (or ears) that listen to the messages of the chemical messenger molecules as they float in the intercellular fluid surrounding every cell. Another way to think of this is to consider each receptor site as a lock that is capable of receiving particular types of chemical messenger keys, called ligands (rhymes with "Bye Hands").
