Question 9

Summarize the defecation reflex.

Accepted Answer

The parasympathetic ^-mediated defecation reflex is initiated when mass movements force fecal material into the normally empty rectum. Stretch receptors transmit the sensation of rectal distention to the spinal cord. Parasympathetic neurons cause smooth muscle in the sigmoid colon and rectum to contract, and the internal anal sphincter to relax. Impulses from the cerebral cortex trigger relaxation of the external anal sphincter and contraction of the levator ani muscle. These combined movements allow the feces to pass and are assisted by contraction of the abdominal muscles against a closed glottis (Valsalva maneuver), which increases intra ^-abdominal pressure.
