Question
Preganglionic axons of parasympathetic neurons terminate in ganglia locatedMultiple choice question.within internal organs.the sacral regions of the spinal cord.in a chain that runs parallel to the spinal cord.
Solution
The correct answer is "within internal organs." The parasympathetic nervous system is part of the autonomic nervous system that conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract. The preganglionic axons of parasympathetic neurons terminate in ganglia located within the internal organs they innervate. This is in contrast to the sympathetic nervous system, where the ganglia are located in a chain that runs parallel to the spinal cord.
