Esophageal sphincter

A circular band of muscle that closes the last few centimeters of the esophagus and prevents the backward flow of stomach contents.

Mentioned in: Achalasia

sphincter

a circular muscle that constricts a passage or closes a natural orifice. When relaxed, a sphincter allows materials to pass through the opening. When contracted, it closes the opening. The principal abnormalities relate to function. Failure to open may be because of spasm or achalasia, due usually to failure of parasympathetic nerve supply. Failure to close usually due to absence of sympathetic nerve supply. The important sphincters are the anal, ileal, pharyngoesophageal, pupillary, pyloric, reticulo-omasal, teat, urethral, vaginal and vesical.

cardiac sphincter

the functional sphincter at the gastric end of the esophagus.

sphincter control

is by the autonomic nervous system.
