What else can I help you with?
Which is not a result of parasympathetic stimulation?
dilation of the pupils
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.
What system controls the flow of saliva?
The autonomic nervous system controls the flow of saliva. The production of saliva is regulated by both the parasympathetic and sympathetic nervous systems, with the parasympathetic system increasing saliva production and the sympathetic system decreasing it.
Does the heart receive both parasympathetic and sympathetic stimulation?
yes
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 happens if the heart receives more sympathetic stimulation than parasympathetic stimulation?
increase its rate and force of contraction
What is salivation controlled by?
Salivation is primarily controlled by the autonomic nervous system, specifically the parasympathetic nervous system. When stimulated, the parasympathetic nervous system activates salivary glands to produce saliva, which helps with digestion and swallowing. Additionally, sensory input such as the smell or taste of food can also trigger the salivary reflex.
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 .
Does sympathetic or parasympathetic stimulation produce thicker saliva with more mucus?
Sympathetic. Parasympathetic secretes thin saliva rich in amylase.
Does parasympathetic stimulation inhibit digestion?
No, parasympathetic stimulation actually enhances digestion. It promotes the release of digestive enzymes and increases blood flow to the digestive organs, which helps with the absorption and processing of nutrients from food.
How does PNS stimulation affect the lungs?
parasympathetic system (PSNS) will a)vasoconstrict the lumen of airway by contracting smooth muscle cells along the conducting passage via M3 Receptor, b)increase mucus secretion via M3 Overall it'll interfere with normal breathing pattern and obstruct normal breathing.
