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. Stretch receptors located in the rectal wall initiate the defecation reflex inresponse to an incoming mass movement.C. The defecation reflex involves contraction of the rectal wall and simultaneous relaxation of the internal anal sphincter.D. Digestive fluids secreted from the pancreas and gall bladder contain enzymesthat act on the smooth muscle of the intestine, stimulating peristalsis.E. Conscious signals from the cortex will allow for relaxation of the external anal sphincter (when appropriate!).arrow_forwardSometimes the cure for gallstones is to surgically remove the gallbladder.

The damage to Jane’s GI tract is localized to the large intestine (colon), whereas patients with Crohn’s disease may have any part of the GI tract affected in the form of “skip” lesions. B. A patient with Crohn’s disease is more likely to have bloody stool than Jane. C. The entire thickness of the Jane’s intestinal wall (mucosa, submucosa, smooth muscle, and serosa) may be affected, whereas only the mucosa is affected in patients with Crohn’s disease. D.
