Here's a breakdown of the word:
* Secret refers to the substance being released.
* -agog comes from the Greek word *agogos*, meaning "leading" or "bringing forth."
So, a secretagogue essentially "brings forth" a secretion.
Examples of secretagogues:
* Cholecystokinin (CCK): Stimulates the release of bile from the gallbladder.
* Insulin: Stimulates the release of glucose from the liver.
* Gastrin: Stimulates the release of gastric acid from the stomach.
Note: The term secretagogue is often used in the context of medicine and pharmacology.
