What may result if the pharyngoesophageal sphincter does not function properly? asked in Anatomy & Physiology by Aleix. A) Food will cause the esophagus to collapse. B) Food will bypass the esophagus. C) Food will be swallowed much faster. D) Food cannot enter the esophagus. Remaining Time: 59 Minutes, 45 Seconds. Question Completion Status: QUESTION 1 The Inferior Esophageal Sphincter Is Also Known As The: Cardiac Sphincter. O Pyloric Sphincter. Pharyngoesophageal Sphincter. Pharyngealgastric Sphincter. O Esophageal Hiatus. QUESTION 2 The Alveolar Cell That.
The upper esophageal sphincter (UES) and lower esophageal sphincter (LES) assure unidirectional flow of the swallowed bolus. However, they must relax during swallowing so as not to pose a barrier to flow. The best-described disorder of sphincteric function is achalasia. This is . You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them.
Filed under: Pharyngoesophageal sphincter. Motor Function of the Pharynx, Esophagus, and its Sphincters (San Rafael, CA: Morgan and Claypool, ), by Ravinder K. Mittal (illustrated HTML at NIH) Items below (if any) are from related and broader terms. The upper esophageal sphincter (UES) is a to cm manometric high-pressure zone located between the pharynx and esophagus (Figure 1). Because of its location, this region has also been referred to as the pharyngo-esophageal segment or PES. The UES specifically refers to the intra-luminal high-pressure zone visualized on manometry.

Perry. A diagnosis of "spasm" or "achalasia" of the sphincter requires confirmation by other techniques. Manometric studies may be used to explore the high pressure zone extending over 3 to 4 cm at the pharyngoesophageal junction, and to record the pressure changes after deglutition in the pharynx, the sphincter and the upper part of the esophagus.

Gastroenterology The area of pharyngoesophageal sphincter is of great interest to the otolaryngologist. The diseases, dysfunctions, and dangers of inadequate visualization, plus the accidents of instrumentation and spontaneous diseases and poison ingestion, the difficulties of abnormal function have made it a source of interest, worry, and wonder.
The observations have established normal values for measurements of UES function and, in addition, have shown that (1) catheter variables significantly influence the measurement of upper sphincter tonic pressure, (2) pressures recorded with the catheter-mounted transducer are most reproducible, and (3) pharyngoesophageal motility patterns vary.
The pharyngoesophageal junction is surrounded by the upper esophageal sphincter, also known as the cricopharyngeus muscle. This muscle is actually a portion of the inferior pharyngeal constrictor.
In turn, the gastroesophageal junction is surrounded by the lower esophageal sphincter, also known as the cardiac sphincter. Pharyngoesophageal perforation after anterior cervical spine surgery is already well-documented [1–3], however, another type of esophageal complication, pharyngoesophageal diverticulum is not so well-recognized.

Fingerprint Dive into the research topics of 'The pharyngoesophageal segment: Normal structure and function'. Together they form a unique fingerprint. Modulation of the timing and the extent of sphincter opening during swallowing is intimately correlated with the volume and physical properties of the bolus, along with co-ordinated activity.

When relaxed, a sphincter allows materials to pass through the opening. When contracted, it closes the opening. Four main sphincter muscles along the alimentary canal aid in digestion: the cardiac sphincter, the pyloric sphincter, and two anal.
A sphincter is a ring-like muscular structure that, whenever closed, stops the passage via the tube that it is protecting. The lower portion of the esophagus on the junction of the esophagus along with the stomach is covered by the lower esophageal sphincter or gastroesophageal is also referred to as the cardiac sphincter or cardioesophageal sphincter, named from the surrounding.
The concept of abnormal function of the upper esophageal sphincter was supported by the careful cineradiographic studies of Lund and of Ardran and Kemp who noted premature contraction of the pharyngoesophageal sphincter in patients with pharyngoesophageal diverticulum.
Core tip: Our study highlights how the presence of Upper esophageal sphincter (UES) abnormalities in patients with achalasia significantly predicted poorer treatment response as compared to those with normal UES function, irrespective of the type of treatment received or achalasia sub-type.
We believe this finding is novel and represents an opportunity to more fully characterize upper.
