What two types of smooth muscle surrounds the esophagus?
The body of the esophagus is bounded by physiologic sphincters known as the upper and lower esophageal sphincters. The upper sphincter is composed largely of a muscle that is closely associated with the larynx. When relaxed, as it is during swallowing, this muscle pulls the larynx forward and aids in routing food into the esophagus instead of the larynx. The lower sphincter is simply the muscle that surrounds the esophagus just as it enters the stomach. Both the upper and lower sphincter are closed except during swallowing, which prevents constant entry of air from the oral cavity or reflux of stomach contents.
