During periods of stress or increased activity, the sympathetic division of the autonomic nervous system predominates. And during periods of rest, the parasympathetic division of the autonomic nervous system predominates
If you think of it as "fight or flight" it becomes a lot The_functions_of_the_Sympathetic_nervous_system_and_the_parasympathetic_nervous_systemto remember how it works. It increases the heart rate, increases energy production, decreases the GI system function, etc.
1. Increase cardiac output
2. Bronchodilation
3. Conversion of glycogen to glucose
Generally fight-or-flight.
Sympathetic nerves are the efferent pathway of one population of the autonomic nervous system. The autonomic nervous system controls reflex activities. The most important might be the control of the vascular system. Sympathetic neurons act to increase blood pressure. Increasing the pace of the heart and the constricting peripheral vasculature.
It is the fight or flight response so that means,
They are meant for fight or flight response.
The procedure is done to increase blood flow and decrease long-term pain in certain diseases that cause narrowed blood vessels.
You have sympathetic trunks located by either side of vertebral column. You have thoracolumber out flow for sympathetic system. You do not have nerves for the same.
Sympathetic nerves from the cardiopulmonary division T2-T5
The sympathetic nervous system branches include the sympathetic trunk and the splanchnic nerves. The sympathetic trunk contains the sympathetic ganglia, which are responsible for sending signals to various target organs in the body. The splanchnic nerves innervate the abdominal organs and play a role in regulating their function.
i think that it is the sympathetic nervous system
You have local nerve plexus in case of small intestine. The small intestine is also supplied by nerves from parasympathetic and sympathetic nervous system. The parasympathetic supply augments the peristalsis, secretion of enzymes. Sympathetic nerves inhibit the same. Together they work better.

Sympathetic nerve stimulate the pace maker. So that heart rate increases. Parasympathetic stimulation decreases the heart rate.
Sympathetic.
The parts of the CNS that give rise to sympathetic nerves are the thoracic and lumbar regions of the spinal cord.

A study of the vasomotor nerves of the rabbit's ear contained in the third cervical and in the cervical sympathetic nerves
The sympathetic nervous system branches include the sympathetic trunk and the splanchnic nerves. The sympathetic trunk contains the sympathetic ganglia, which are responsible for sending signals to various target organs in the body. The splanchnic nerves innervate the abdominal organs and play a role in regulating their function.
Preganglionic fibers for the SNS release ACh; so a drug that stimulates ACh receptors would stimulate the postganglionic fibers of sypathetic nerves, resulting in increased sympathetic activity
Splanchnic nerves
i think you mean nervous systems; central (CNS), autonomic (ANS), and the sympathetic or para-sympathetic (SNS).
