(1) It is girdled by the external anal sphincter , a striated muscle structure that is part of the pelvic floor musculature.(2) Anal manometry is performed to assess the anal sphincter , pelvic floor, and associated nerves.(3) This smooth muscle is the involuntary sphincter of the posterior urethra in the male.(4) the anal sphincter(5) Then your brain tells your pelvic floor muscles to relax and your sphincter (the opening at the neck of your bladder) to open.(6) This rapidly closes the duodenal sphincter to contain the stomach contents.(7) It is especially to be remembered in sphincteral paralyses, so common after long illness in which spinal enervation has played an important role.(8) Eighty-five percent of the patients had intrinsic sphincteric deficiency, while 15 percent had genuine stress urinary incontinence.(9) Generally, the treatments for sphincteric weakness include pelvic floor exercises, injections of a bulking agent, or an artificial urinary sphincter.(10) He takes note of the threat to his sphincteral cavity and the final resting place of the camera if he takes a picture of me.(11) Accompanying sensory and sphincteric symptoms are also common.(12) The interposed jejunal segment fulfilled efficiently the transit and sphincteral functions of the esophagus.(13) If technical guidelines are rigorously followed, the feared complications associated with surgical procedures, such as anal stricture and sphincteric injuries, are largely reduced.(14) In addition, with respect to the other muscles in the body with an analogous sphincteral activity (gastrointestinal and genitourinary tracts), it is distinguished by the mechanism of contraction, rather than of dilation.(15) It covers the fields of neurology, locomotion, cardiovascular and respiratory pathology as well as sphincteral function.(16) Progestational hormones also affect the force of contraction of the sphincteric muscle and various gastrointestinal hormones may do so as well.
