Question

Quizplus · Accepted Answer

The duodenocolic reflex is a reflex that results in the urge to defecate when the duodenum is distended. This reflex is activated when sensory nerve fibers in the duodenal wall are stimulated by distension or irritation, and send signals to the spinal cord. From there, efferent nerve fibers are activated, leading to a contraction of the colon and the urge to defecate. The other choices are not associated with the defecation reflex triggered by duodenal distension.
