It would increase the pulse, providing it acted upon the cardiac conduction system. There are parasympathetic antagonists which act on other parts of the body, such as the bladder; such drugs would not affect the pulse (theoretically).
No. Muscarinic receptors are affected by acetylcholinergic neurotransmitters (ie. muscarine, atropine). Only the parasympathetic nervous system have muscarinic receptors. Epinephrine affects adrenergic receptors (symapthetic nervous system).
Sympathetic nerve stimulate the pace maker. So that heart rate increases. Parasympathetic stimulation decreases the heart rate.
What would happen if the nervous system was not functioning properly? How would this affect the muscular system?

it damages the central nervous system

Sympathetic
The parasympathetic nervous system allows for the relaxation of the GI muscles, which allows excretion. So in other words, constipation is more a product of the sympathetic nervous system, which if stimulated, will divert blood flow from the gut and delay defecation, causing constipation. If the parasympathetic nervous system is blocked or the sympathetic system stimulated, constipation can result.
The iris is not innervated directly, however the iris sphincter muscle is affected by the sympathetic and parasympathetic nervous systems. Sympathetic stimulation causes pupil dilation while parasympathetic nervous system causes pupil constriction. The parasympathetic response is quicker because of the proximity of a parasympathetic ganglion (ciliary ganglion) to the eye. The sympathetic response is slower because all sympathetic ganglia are confined to the spinal cord. This is the reason why people adjust faster to a bright shining light than darkness.
No. Muscarinic receptors are affected by acetylcholinergic neurotransmitters (ie. muscarine, atropine). Only the parasympathetic nervous system have muscarinic receptors. Epinephrine affects adrenergic receptors (symapthetic nervous system).
Gravity inhibits flight.
Doxorubicin inhibits methylation of DNA.
Sympathetic nerve stimulate the pace maker. So that heart rate increases. Parasympathetic stimulation decreases the heart rate.
there are nevers that affect your heart rate there are twoSympathetic and parasympathetic (vagus).hope i helped :D
Massage therapy can help relax and reduce tension in the central nervous system by stimulating the release of endorphins, which are the body's natural painkillers. It can also reduce stress hormones like cortisol, promoting a sense of relaxation and well-being. Additionally, massage therapy can improve circulation, which can help deliver nutrients and oxygen to the nervous system, supporting overall function.
The pineal gland
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.
