Question
Chapter 15, Problem 3CRCAQ
Summary Introduction
To review:
The absence of pain in case of a tear in the intestinal mucosa as compared to the feeling of pain in case of a tear in the skin of anus and rectum.
Introduction:
Defecation is the excretion of the undigested food out of the body through the anal opening. The visceral pain displays an atypical characteristic. It is generally observed that a cut or tear in visceral organs do not produce much pain. However, excessive contraction of smooth muscles and stretching can lead to intense pain.

- The normal mechanism of defecation involves:A. Stretch receptors located in the duodenum and jejunum initiate a long-lasting reflex that relaxes the internal anal sphincter several hours after food initially passes from the stomach to the intestines.B.

The defecation reflex involves contraction of the rectal wall and simultaneous relaxation of the internal anal sphincter.D.
