Rectoanal reflex in healthy subject.
The present work was performed in order to examine the rectoanal reflex in healthy subject. Our findings suggest that the fecal continence is sustained by both the anal sphincters. The maximal anal pressure at rest is governed by activity of the internal sphincter while the external anal sphincter promptly contracts when the rectum is distended.
