Which one of the following statements concerning the parasympathetic nervous system is correct? A. The parasympathetic system uses norepinephrine as a neurotransmitter. B. The parasympathetic system often discharges as a single, functional system. C. The parasympathetic division is involved in accommodation of near vision, movement of food, and urination. D. The postganglionic fibers of the parasympathetic division are long compared to those of the sympathetic nervous system. E. The parasympathetic system controls the secretion of the adrenal medulla.

The parasympathetic system maintains essential bodily functions, such as vision, movement of food, and urination. It uses acetylcholine, not norepinephrine, as a neurotransmitter, and it discharges as discrete fibers that are activated separately. The postganglionic fibers of the parasympathetic system are short compared to those of the sympathetic division. The adrenal medulla is under control of the sympathetic system.

The parasympathetic division is involved in accommodation of near vision, movement of food, and urination is the statement that is correct.

The parasympathetic nervous system is made up of neurons and nerves that belong to the cranial nerves and another dedicated to the ganglia and the nerves that leave the spinal cord and that have the pelvic organs as their destination.

The parasympathetic nervous system remains active while the body is resting and during the development of the digestive process.

It is responsible for stimulating digestion, defecation and urination and decreases the heart rate, respiratory rate and blood pressure, it also contracts the pupils.

Therefore, we can conclude that the parasympathetic nervous system activates the function of the vagus, spinal, oculomotor, glossopharyngeal and sacral nerves.
