Question

When reviewing the general functions of the parasympathetic division, which of the following statements best summarizes the physiologic outcome?

a) The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.
b) The parasympathetic division is considered a catabolic system because it functions to make glucose readily available to the cells.
c) The parasympathetic division mobilizes energy reserves in the liver and skeletal muscle for immediate release.
d) The parasympathetic division functions in short-term, physiologic crisis management.

Answer 1

The best summary of the parasympathetic division's function is that it conserves energy and lowers metabolic rate, counterbalancing the sympathetic division. This encompasses the 'rest and digest' activities, which restore the body to a peaceful state after stress.

Step-by-step explanation:

When reviewing the general functions of the parasympathetic division of the autonomic nervous system, the statement that best summarizes the physiologic outcome is: 'The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.' This is because the parasympathetic division is principally involved in bringing the body back to a state of rest after the exertion of the fight-or-flight response initiated by the sympathetic division.

The correct option, based on this explanation, is: a) The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.
