Pelvis and Perineum .:: Defecation is a complex action requiring coordination and sequential activation of a large number of muscles. It is controlled by the autonomic nervous system, but is also under voluntary control. Defecation is initiated by distension of the rectum by feces arriving from the sigmoid colon. This sensation leads to a chain of events which ends in expulsion of feces from the anus. The act of defecation is voluntarily controlled in healthy, normally functioning people.
