Three-neuron reflex arcs that exist entirely within the walls of the digestive tract.
A) rami communicantes
B) enteric nervous system
C) inferior hypogastric plexi
D) sympathetic trunks
E) cholinergic fibers

Question

Quizplus · Accepted Answer

The enteric nervous system consists of a network of neurons that exists entirely within the walls of the digestive tract, including three-neuron reflex arcs. These reflex arcs can control local contractions and secretions to aid in digestion. The other choices (rami communicantes, inferior hypogastric plexi, sympathetic trunks, and cholinergic fibers) are all components of the autonomic nervous system, but they are not specific to the digestive tract or reflex arcs within it.
