Propulsion Disorders of the Throat
Introduction
Propulsion disorders of the throat can cause trouble moving food from the upper part of the throat into the Throat and Esophagus (the hollow tube that leads from the throat [pharynx] to the stomach). People usually notice they have Some people feel as if they have a lump or mass in their throat when no mass is actually there. If this sensation is unrelated to swallowing, it is termed Lump in Throat . As a person swallows, food moves from the mouth to the throat, also called the pharynx (1). The upper esophageal sphincter opens (2) so that food can enter the esophagus, where waves of muscular contractions, called peristalsis, propel the food downward (3). The food then passes through the diaphragm (4) and lower esophageal sphincter (5) and moves into the stomach. Themost common causeof disorders of the muscles or nerves of the throat is Overview of Stroke None Other disorders that can affect the throat muscles or nerves include Autoimmune Myositis , the upper esophageal sphincter (cricopharyngeal muscle) remains closed, or it opens in an uncoordinated way. An abnormally functioning sphincter may allow food to repeatedly enter the windpipe and lungs, which may lead to recurring lung infections and eventually to chronic lung disease. A surgeon can cut the sphincter so that it is permanently relaxed. If left untreated, the condition may lead to the formation of a Zenker diverticula (pharyngeal diverticula) , a pouch that is formed when the lining of the esophagus pushes outward and backward through the cricopharyngeal muscle.
