Sample questions

1. Which of the following BEST describes the organization of the enteric nervous system?

a.It consists of a single plexus located in the submucosa that controls blood flow.

b.It is primarily a sensory system that relays information to the central nervous system.

c.It is composed of the myenteric and submucosal plexuses that regulate digestive functions.

d.It is a collection of ganglia located outside the gastrointestinal tract wall.

2. The myenteric plexus is primarily responsible for which of the following functions?

a.Providing the main parasympathetic input to the gastrointestinal tract.

b.Controlling the contraction of the circular and longitudinal muscle layers for peristalsis.

c.Regulating the movement of water and electrolytes across the intestinal wall.

d.Sensing the chemical composition of the luminal contents.

3. Which of the following statements about the enteric nervous system is TRUE?

a.It operates independently of the central nervous system but receives input from it.

b.It contains fewer neurons than the total of all other peripheral ganglia.

c.Its neurons exclusively use acetylcholine as a neurotransmitter.

d.It is derived from the trunk neural crest during embryonic development.

4. A researcher is studying the effects of chronic stress on gastrointestinal function. Which of the following is the MOST likely mechanism by which stress alters enteric nervous system activity?

a.Modulation of enteric neural circuits through altered sympathetic and parasympathetic input.

b.Direct inhibition of the myenteric plexus by circulating glucocorticoids.

c.Permanent destruction of enteric neurons due to stress-induced inflammation.

d.Reduced blood flow to the gut leading to ischemic damage to the submucosal plexus.

5. Which of the following statements about the enteric nervous system (ENS) is FALSE?

a.It is capable of autonomous function independent of the CNS.

b.It contains both excitatory and inhibitory motor neurons.

c.It utilizes more than 30 different neurotransmitters.

d.Its neurons are all derived from the neural tube.
