pharyngoesophageal junction

The pharyngoesophageal junction is the area where the throat (pharynx) connects to the esophagus, the tube that carries food to the stomach. It’s an important muscular gateway that helps coordinate swallowing and prevents food or liquids from going the wrong way. This junction includes a ring of muscle called the cricopharyngeus, which relaxes to allow food to pass into the esophagus and then contracts to prevent reflux. Proper function of this area is essential for swallowing safety and efficient movement of food from the mouth to the stomach.
