Which of the following statements concerning the parasympathetic division of the autonomic nervous system is false? Preganglionic neurons are located in the brain stem and sacral region of the spinal cord. The ganglionic neurons always release acetylcholine. The actions of the parasympathetic division are more localized than those of the sympathetic division. Ganglionic neurons are located in ganglia within or near to effectors. Preganglionic fibers are relatively short and postganglionic fibers are relatively long.

Preganglionic fibers are relatively short and postganglionic fibers are relatively long.

When reviewing the general functions of the parasympathetic division, which of the following statements best summarizes the physiologic outcome? The parasympathetic division is considered a catabolic system because it functions to make glucose readily available to the cells. The parasympathetic division mobilizes energy reserves in the liver and skeletal muscle for immediate release. The parasympathetic division functions in short term, physiologic crisis management. The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.

The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.

Dual innervation refers to an organ receiving two nerves from the spinal cord. both sympathetic and parasympathetic innervation. nerves from both the brain and the spinal cord. both autonomic and somatomotor nerves. both sensory and motor nerves.
