Which is not a result of parasympathetic stimulation?
dilation of the pupils
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.
What is the agent that blocks parasympathetic nerve impulses?
antimuscarinic - refers to an agent used to block parasympathetic effects such as salivation & bradycardia.
Does parasympathetic stimulation inhibit digestion?
No, it stimulates it
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 is parasympathetic stimulation?
Parasympathetic stimulation is a process that takes place in the peripheral nervous system. This is a process where signals are carried throughout the body.
Does the heart receive both parasympathetic and sympathetic stimulation?
yes
What system controls the flow of saliva?
The autonomic nervous system controls salivation.Parasympathetic stimulation increases salivationSympathetic stimulation decreases salivation
What happens if the heart receives more sympathetic stimulation than parasympathetic stimulation?
increase its rate and force of contraction
Would The parasympathetic nervous system control and allow for active diuresis?
Parasympathetic stimulation stimulates the muscarinic receptors (and nicotinic) leading to increased Salivation, Lacrimation, Urination, Defacation, increased Gastric motility, Emesis etc Baroreceptors detect increased BP (vessel stretch) and increase vagal tone - > increase parasympathetic tone ->increase muscarinic stimualtion - > diuresis Also consider the effect of Atrial Natruetic Peptide and its effect...
The effects of sympathetic and parasympathetic stimulation of the salivary glands are called?
complementary
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 .
