The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
The anus is made up of two sphincter muscles: the internal anal sphincter, which is involuntary, and the external anal sphincter, which is under voluntary control. The anus also contains sensitive nerve endings that detect the passage of stool.
Vicodin, which contains hydrocodone and acetaminophen, can cause sphincter of Oddi spasm due to the opioid component's effect on smooth muscle contraction. It is important to consult a healthcare provider if you experience symptoms of sphincter of Oddi dysfunction, as it can lead to serious complications like pancreatitis.
Sphincter of Oddi.
The internal urethral sphincter an involuntary sphincter that keeps the urethra closed when urine is not being used. The external urethral sphincter is fashioned by skeletal muscles as the urethra passes thorugh the pelvic floor.This sphincter is voluntary controlled.
The anal sphincter and the bladder sphincter in potty trained children and in most other people whose spinal cords are intact or are not suffering from some diseases.

Sphincters can be classified into functional and anatomical sphincters:Anatomical sphincters have a localised and often circular muscle thickening to facilitate their action as a sphincter.Functional sphincters do not have this localised muscle thickening and achieve their sphincteric action through muscle contraction around (extrinsic) or within (intrinsic) the structure.Sphincters can also be voluntarily or involuntarily controlled:Voluntary sphincters are supplied bysomatic nerves.Involuntary sphincters are stimulated byautonomic nerves.
