What causes the gastroesophageal sphincter to open to allow food to enter the stomach?
the arrival of the peristaltic wave at the stomach
Sphincter found between the esophagus and the stomach?
What is the function of the cardiac sphincter?
When the cardiac sphincter relaxes food enters the?
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
The sphincter muscle that controls access to the stomach from the esophagus is called?
cardiac sphincter; or gastroesophageal sphincter; or lower esophageal sphincter (LES); or esophageal sphincter from http://en.wikipedia.org/wiki/Cardia
Ring like muscle that controls the flow from the stomach to the small intestine?
lower esophageal sphincter or gastroesophageal sphincter
Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
The stomach sphincter that keeps food from reentering the esophagus when the stomach contracts is known as the?
It is known as the lower esophageal sphincter or sometimes the cardioesophageal sphincter.
Is cardioesophageal and gastroesophageal same thing?
No. Cardio- = heart Gastro- = stomach Esophageal = of or pertaining to the esophagus Edit- Yes. The Lower Esophageal Sphincter (LES) is also referred to as the Cardioesophageal Sphincter and the Gastroesophageal Sphincter. This sphincter separates the esophagus from the stomach and is usually in a closed position. When there is weakness in the sphincter gastric juices may go up into the esophagus resulting in heartburn.
How does gastroesophageal reflux disease lead to damage to the cells of the esophageal lining?
the esophageal sphincter allows partially digested food and excess stomach acid to flow back into the esophagus.
What should gastroesophageal reflux surgery accomplish?
All gastroesophageal reflux surgery, including Nissen fundoplication, attempts to restore the normal function of the lower esophageal sphincter (LES).
What is called Backflow (reflux) of gastric contents into esophagus due to malfunction of the lower esophageal sphincter?
Gastroesophageal reflux disease (GERD)
