Abstract

Preserving continence of bowel contents and effective defecation with complete, spontaneous elimination of stool rely on an intact complex neuromuscular anorectal unit composed of the rectum, puborectalis muscle, internal anal sphincter, external anal sphincter, the levator ani, as well as its neurological innervation through lumbosacral plexus nerves, particularly the pudendal nerve. This article reviews each of these components, and their physiological role in providing normal anorectal function, and discusses the evaluation of anorectal neuro-physiological function, and morphology using high-resolution anorectal manometry, translumbosacral anorectal magnetic stimulation (TAMS), defecography, and anal endosonography.
