Question
- The parasympathetic division controlsa. fight-or-flight response.b. increased heart rate and blood pressure.c. increased digestion and decreased heart rate.d. increased release of epinephrine and production of glucose.e. increased heart rate and decreased digestion
Solution
The parasympathetic division controls c. increased digestion and decreased heart rate.
Here's why:
The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system. Its primary role is to conserve and restore energy in the body, often referred to as the "rest and digest" system.
When the parasympathetic nervous system is activated, it promotes relaxation, slowing of the heart rate, and increased digestion. This is because during periods of rest and relaxation, the body can focus on maintenance tasks like digestion.
So, the parasympathetic division does not control the fight-or-flight response, increased heart rate and blood pressure, or the increased release of epinephrine and production of glucose. These are all functions of the sympathetic nervous system, the other main division of the autonomic nervous system, which prepares the body for action during stressful or emergency situations.
