Difference between Sphincter Muscle and Sphincter

SPHINCTER MUSCLE vs SPHINCTER: NOUN

A muscle which surrounds, and by its contraction tends to close, a natural opening.
The sphincter recti, sphincter internus, or internal sphincter surrounds the lower end of the rectum, forming a muscular ring about an inch in extent and a quarter of an inch thick, and consists of an aggregation and thickening of the circular fibers of the gut. This sphincter is involuntary, and in health maintains its tonic contractility, which yields by reflex action to the pressure of the contents of the bowel.
The sphincter ani proper, sphincter externus, or external sphincter is a thin, flat plane of voluntary muscular fibers supplied by hemorrhoidal branches of nerves from the sacral plexus, surrounding the anus, subcutaneous and intimately adherent to the integument, of elliptical form 3 or 4 inches in long diameter, and an inch wide across. It arises from the tip of the coccyx, and is inserted into the tendinous raphe of the perineum. Like most sphincters. it consists of symmetrical lateral halves united by a raphe in front of and behind the opening it incloses.
An orbicular, circular, or annular muscle surrounding and capable of closing a natural orifice or passage of the body.
A ringlike muscle that normally maintains constriction of a body passage or orifice and that relaxes as required by normal physiological functioning.
A ring of muscle that contracts to close an opening

In people with a weak lower esophageal sphincter muscle, this results in heartburn.
SUI can also occur when the sphincter muscle that controls the urethra weakens.
Disturbance of the normal synergistic coordination between bladder contraction and external urethral sphincter muscle relaxation during voiding.
Injectable implants feed bulking material into the urethra to control UI caused by a weak sphincter muscle.
The anal sphincter muscle remains tight, however, and bowel movements will occur on a reflex basis.
That sphincter muscle relaxes for about a second every time we swallow saliva, food, or drink.
Peppermint can relax the esophageal sphincter muscle, which could exacerbate your problem.
Surgery on My sphincter muscle in February of this year.
Urodynamic tests examine bladder and sphincter muscle function.
Lateral internal sphincterotomy or opening of the inner anal sphincter muscle is sometimes performed during hemorrhoidectomy in patients with high resting sphincter pressures.

As the number of transient lower esophageal sphincter relaxations increased, it is possible that simple carbohydrates affect mediators of lower esophageal sphincter function.
LESP: lower esophageal sphincter pressure, IRP: integrated relaxation pressure, LES: lower esophageal sphincter, and POEM: peroral endoscopic myotomy.
The evacuation of bowel contents depends on action by the muscles of both the involuntary internal sphincter and the voluntary external sphincter.
For the urine to exit the bladder, both the autonomically controlled internal sphincter and the voluntarily controlled external sphincter must be opened.
Two rings of muscle, the internal anal sphincter and external anal sphincter, surround the anal canal.
Effective treatment with internal sphincter resection mandates that the tumor not penetrate the internal sphincter.
If there is resistance on insertion, this indicates good internal sphincter tone, it is only during defecation that the sphincter should relax.
Lateral internal sphincterotomy or opening of the inner anal sphincter muscle is sometimes performed during hemorrhoidectomy in patients with high resting sphincter pressures.
Alternate approaches have proposed resection of the internal sphincter as well as superficial external sphincter.
External anal sphincter, which contains skeletal muscle tissue called the gastroesophageal or cardiac sphincter.
