What effect does the sympathetic and parasympathetic nervous system have on the digestive system?

The parasympathetic nervous system is a division of the autonomic nervous system (along with the sympathetic nervous system, and the enteric nervous system). In simple terms, the SNS can be thought of as the body's gas pedal, and the PNS as the brake. So where the SNS deals with 'fight or flight' the PNS deals with 'rest and digest'. In other words, the PNS is often inhibitory. For example, it can act to slow down heart rate, enhance the peristaltic contractions of the gut, or increase secretions of digestive enzymes. In can also cause vasodilation (make the blood vessels wider) around your gut after meals: this means more blood flows to your intestive and stomach after you've eaten a meal, allowing you to digest what you've eaten.

∙ 13y agoYour parasympathetic system is your rest and digest system. When you are digesting you would be trying to move food through, Right? Secretions might help. You would also have a lot of blood to the area, to work all the muscle moving the food.
Now, your sympathetic system would be if you got attacked by a bear with a knife. Then your body would inhibit the smooth activity in the walls of the small intestine.
Hope I helped.

Explain the difference between sympathetic and parasympathetic reactions as they occur in the autonomic nervous system?
The sympathetic nervous system is most active when you are in an emergency, exercising, or an exciting or embarrassing situation. It is often referred to as the "fight-or-flight" system. It increases the heart rate, blood pressure, and blood glucose levels. It also dilates the bronchioles of the lungs, and dilates the blood vessels of the skeletal muscles. This nervous system enables the body to cope rapidly with situations. The parasympathetic nervous system is active when the body is resting. It is referred to as the "resting-and-digesting" system. It conserves your body's energy by slowing the heart rate. It also promotes digestion.sypmathetic is the "fight or flight" response and the parasympathetic is the "rest and digest" responses
Which body systems does caffeine have an effect on?
Directly or indirectly, mostly sympathetic nervous system. The sympathetic nervous system is responsible for the 'flight or flight' response which was first studied by Walter Canon. The role of the sympathetic nervous system is to prepare the body for action, and in the case of caffeine, it makes you more alert, raises your blood pressure, and increases your heart rate.
What is the effect of parasympathetic stimulation on this salivary glands?
Sympathetic stimulation of your salivary glands suppresses the activity of the glands and salivation decreases. During parasympathetic stimulation you to salivate.
Why the symptoms of hyperthyroidism may be confused with a disorder of the autonomic nervous system?
Hyperthyroidism may be confused with a disorder fo the autonomic nervous system primarily because of the the permissiveness (biology) of the thyroid hormones on the hormones and neurotransmitters (epinephrine and norepinephrine) of the sympathetic division of the autonomic nervous system. Thyroid hormones exacerbate the effect of the sympathetic nervous system, causing "speeding up" of various body systems and symptoms resembling an overdose of epinephrine (adrenaline). These include fast heart beat and symptoms of palpitations, nervous system tremor such as of the hands and anxiety symptoms, digestive system hypermotility (diarrhea), considerable weight loss and unusually low lipid panel (cholesterol) levels as indicated by a blood test.
What nervous system regulates the blood?
A good example is the baroreflex. Pressure sensors signal to the nervous system to increase venous return when we go from lying to standing. The nervous system controls the contraction of the veins which forces blood from the legs back to the heart. The nervous system can also increase the stimulation to the heart increasing the number of beats per minute. The net effect of the blood that is returned into the circulation and the increases heart rate act to restore blood pressure to it's proper level.
Why sympathetic nervous system has generalized effect while parasympathetic nervous system has localized effect?
the ratio of a preganglionic neuron to
Does the effect of epinephrine mimic the effect of the sympathetic nervous system or the parasympathetic nervous system?
epinephrine (or adrenaline in the UK) mimics the effects of norepinephrine (noradrenaline in UK), so activates the SNS, not the PSNS.
What is the parasympathetic and Sympathetic effect on the stomach?
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility
What is the sympathetic effect on the heart?
Heart rate increases with sympathetic nervous system. There is increase in stroke volume and cardiac output. With stimulation of vagus nerve or parasympathetic nervous system, You have decrease in heart rate. There is decrease the stroke volume and cardiac output.
Does coronary vessels have both parasympathetic and sympathetic innervation?
Yes. Sympathetic nerve stimulation dilates the blood vessels. Parasympathetic nerve stimulation constricts the blood vessels. The sympathetic nerve stimulation effect is more pronounced.

What effect would a drug that blocks the parasympathetic nervous system have on peristalsis in the GIT?
increase motility
What has the author Naeema C Degani written?
Naeema C. Degani has written: 'Effect of ethanol on the sympathetic nervous system' -- subject(s): Physiological effect, Sympathetic nervous system, Alcohol, Alcohol in the body
Is increased cognitive functioning an antagonistic effect of the sympathetic nervous system?
no, increased cognitive functioning is not
How does the sympathetic nervous system work in stress?
The sympathetic nervous system is the part of the autonomic nervous system originating in the thoracic and lumbar regions of the spinal cord that in general inhibits or opposes the physiological effects of the parasympathetic nervous system, as in tending to reduce digestive secretions, speeding up the heart, and contracting blood vessels.
How does the somatic nervous system differ from the autonomic nervous system?
The somatic nervous system controls the voluntary movement of skeletal muscles, such as when you move your arm. The autonomic nervous systems controls the involuntary actions of internal organs and glands. The beating of your heart is controlled by this system. The autonomic nervous system is further broken up into two parts: the sympathetic, which controls arousal (think fight-or-flight), and the parasympathetic, which controls calming (think rest and digest).
