The sphincter of Oddi regulates the passage of pancreatic juices and bile into the duodenum of the small intestine.
Yes, dysfunction or blockage of the sphincter of Oddi can cause pain in the upper abdomen or right upper quadrant. This may happen due to various reasons, such as spasms, inflammation, or gallstones. It is important to seek medical evaluation if you suspect an issue with the sphincter of Oddi.
the pyloric sphincter regulates the speed at which the chyme (mixture of food from stomach) can enter into the small intestine to be digested. The pyloric sphincter opens and closes according to the acidity of the chyme.
Sphincter deficiency can result directly from pelvic fracture; urethral reconstruction; prostate surgeries; spinal cord injury; neurogenic bladder conditions that include sphincter dysfunction; and some congential conditions.
Bile is produced in the liver and stored in the gall bladder. The presence of lipids in the duodenum causes the release of bile. Ultimately the liver and gall bladder control the release of bile.
The cardiac sphincter, also known as the lower esophageal sphincter, may malfunction due to various reasons such as hiatal hernia, obesity, smoking, certain medications, and certain foods that can relax the sphincter muscle. This dysfunction can lead to conditions like gastroesophageal reflux disease (GERD) and heartburn.
The sphincter pupillae muscle is controlled by the parasympathetic fibers of the oculomotor nerve (cranial nerve III). Activation of these fibers causes constriction of the pupil (miosis).

Inflammation causes pain on movement.
outer anal sphincter
If the cardiac sphincter relaxes, it allows stomach contents to reflux back into the esophagus, causing acid reflux or heartburn. This can lead to symptoms like chest pain, regurgitation, and a sour taste in the mouth. Chronic relaxation of the cardiac sphincter can contribute to gastroesophageal reflux disease (GERD).
