Why does atropine cause tachycardia?
Check out the atropine page at wikipedia.org for your answer.
Are most innervated blood vessels receive only sympathetic nerve fibers?
No, most blood vessels are innervated by both sympathetic and parasympathetic nerve fibers. However, sympathetic nerve fibers typically have a more pronounced effect on blood vessel activity compared to parasympathetic fibers.
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.
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
Why sympathetic nervous system has generalized effect while parasympathetic nervous system has localized effect?

What is the effect of pilocarpine on heart rate?
Pilocarpine stimulates the release of acetylcholine from parasympathetic neurons. Therefore, it stimulates the effect of vagal stimulation on the heart.
What is side effect of pronicy?
It cause cardiac arest
What is the effect rest has on Cardiac output?
Rest has a positive effect on cardiac output. This will promote a healthy heart rate in an individual without subjecting the heart to too much pressure.
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.
In what way do the parasympathetic and the sympatheticnervous systems work together?
Yes. The vagus nerve is a parasympathetic nerve that is almost always stimulating the healthy heart to have a heart rate less than the inherent rate of the SA node. The sympathetic innervation on the heart is minimal and only important during exercise.
