What is parasympathetic stimulation?

Parasympathetic stimulation refers to the activation of the parasympathetic nervous system, which is one part of the autonomic nervous system responsible for rest and digest functions. It slows the heart rate, increases digestion, and promotes relaxation in the body.


What is the effect of parasympathetic stimulation on respiration?

Parasympathetic stimulation typically decreases respiration rate by promoting relaxation through mechanisms such as reducing sympathetic activity, slowing down the heart rate, and decreasing the depth of inhalation. This allows the body to conserve energy and support activities like digestion and rest.


Does coronary vessels have both parasympathetic and sympathetic innervation?

Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.


What causes the activation of the parasympathetic division of the ANS?

The parasympathetic division of the autonomic nervous system is typically activated in situations of rest and relaxation, such as after a meal or during sleep. It counteracts the "fight or flight" response of the sympathetic division, promoting activities like digestion, conservation of energy, and restorative processes in the body. Stimulation of the parasympathetic nerves can also occur through activities like deep breathing, meditation, and gentle exercise.


Does parasympathetic stimulation of the intestine increase or decrease motility and increase or decrease digestive gland secretion?

Parasympathetic stimulation of the intestine increases motility by promoting smooth muscle contractions and enhances digestive gland secretion by stimulating the release of digestive enzymes and fluids.

Is salivation a result of parasympathetic stimulation?

no


What is the effect of parasympathetic stimulation on this salivary glands?

Parasympathetic stimulation increases saliva production in the salivary glands by causing the release of acetylcholine, which binds to receptors on the gland cells and triggers the secretion of saliva. This response helps with digestion and keeps the mouth moist.


Which is not a result of parasympathetic stimulation?

dilation of the pupils


Does the heart receive both parasympathetic and sympathetic stimulation?

yes


What happens if the heart receives more sympathetic stimulation than parasympathetic stimulation?

increase its rate and force of contraction


Is digestion under parasympathetic or sympathetic control?

both


The effects of sympathetic and parasympathetic stimulation of the salivary glands are called?

complementary


Does the parasympathetic or sympathetic inhibit the production of saliva?

The sympathetic inhibits the production of saliva.


Does the parasympathetic nerve acts as a braking system for the heart?

the heart is supplied by both sympathetic and parasympathetic nerve fibers . normally in resting state the heart is under the parasympathetic stimulation ; that's mean if you ramove the parasympathetic stimulation the heart rate will increase up to 100 beat by minute ( under normal conditions in healthy man the heart rate is 72 on average ) , during exercise the heart rate increase and that occurs by the sympathetic stimulation and decreasing the parasympathetic stimulation , and that exactly resemble what occurs when you increase the car velocity : so the we can say that the parasympathetic nerve acts as a braking system of the heart .written by : asma aburas ; medical student .


Does sympathetic or parasympathetic stimulation produce thicker saliva with more mucus?

Sympathetic. Parasympathetic secretes thin saliva rich in amylase.
