title: [Functional anatomy of the anorectal sphincter].
abstract: Sensory component, reflexes and motor components are responsible for anorectal continence. The most important factors are the extraperitoneal part of the rectum, the M.m. sphincter ani internus and externus, the levator ani muscles and the corpus cavernosum recti. The diagnostic of anal incontinence is usually evident from history and physical examination. Additionally intraluminal pressure recordings and electrical measurements are helpful.
