Smooth muscular sphincter: Judy read in her book on medicine that a lissosphincter binds tightly and helps to control the flow of fluid or contents in the body.

Relating to the sphincter: At the urologist's, Sherry found out that the sphincteral opening of the bladder was not functioning properly, and that was why her bladder was leaking.

Pain in a sphincter muscle, as of the anus: Dr. Smart explained to Anne that sphincteralgia in her rectum originated from a ringlike band of muscle fibers that constricted a passage or closed a natural orifice, termed a "sphincter".

Spasmodic contraction of the sphincter on muscles: When a person suffers from sphincterismus, relaxation in warm baths and special ointments or salves are recommended.

Inflammation of a sphincter muscle: A case of sphincteritis can cause pain and also block the normal flow of digestive fluids.

A kind of sphincter muscle: A sphincteroid is a structure or tissue which functions similar to a sphincter in form action, but is not a completely developed sphincter muscle.

The procedure of separating the iris from the cornea in anterior synechia: The method of sphincterolysis uses a digital, manual, or a kind of relaxation and the partial breakdown or even the separation of muscle fibers in a sphincter.
