Cricopharyngeus Muscle (Upper Esophageal Sphincter, UES)
The cricopharyngeus is a sphincter muscle encircling the upper end of the esophagus, also called the upper esophageal sphincter or UES. It is almost always in a contracted state, even during sleep. Its action is like a continually clenched fist. This contraction closes off …
