The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body’s rest-and-digest response. … Its general action is to mobilize the body’s fight-or-flight response. You just studied 30 terms!
What does the parasympathetic nervous system do?
The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.
Which is a function of the parasympathetic nervous system quizlet?
Sometimes called the rest and digest system, the parasympathetic system conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
What is the function of sympathetic and parasympathetic nervous system?
The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.
What is the main difference between the sympathetic and parasympathetic nervous system?
The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.

What is an example of a parasympathetic response?
Examples of parasympathetic responses
Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest. Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.
Is digestive activity sympathetic or parasympathetic?
In general, sympathetic stimulation causes inhibition of gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels. Conversely, parasympathetic stimuli typically stimulate these digestive activities.
What is the effect of the parasympathetic system on the heart rate?
The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.
Where is the parasympathetic nervous system found?
The parasympathetic nervous system is composed of cells located in the brain stem and the sacral region of the spinal cord, and for this reason, it has been referred to as the craniosacral system. The cranial preganglionic neurons project to the cranial nerves with autonomic activity: III, VII, IX, and X.
Is sweating sympathetic or parasympathetic?
Sweating is under the control of the sympathetic nervous system, which orchestrates the body’s reaction to stressful situations and emergencies—sometimes called the “fight or flight” response.
How do you balance the sympathetic and parasympathetic nervous system?
If your sympathetic nervous system is in a constant state of arousal, mindfulness helps restore the proper balance between the sympathetic and parasympathetic systems by increasing the activity of the latter. This creates a feeling of calm and relaxation. Use imagery to stimulate the parasympathetic nervous system.
