Anatomical terminology

The rectal ampulla (or ampulla recti) is the dilated section of the rectum where feces are stored until they are eliminated via the anal canal. The caliber of the rectum at its commencement is similar to that of the sigmoid colon, but near its termination it dilates, forming the ampulla. An ampulla is a cavity, or the dilated end of a duct, shaped like a Roman ampulla.
