Defecation Reflex

The defecation reflex is essential in getting rid of body waste in the form of stool. This reflex is felt when the colon muscles contract to push the stool toward the rectum which signals the brain when stretched. It then triggers the anal sphincters which makes the individual go to the bathroom. The two main defecation reflexes are myentric and parasympathetic. The myentric defecation reflex cannot be controlled while the parasympathetic defecation reflex can be controlled.
