Generally you can think of sympathetic stimulus causing contraction of smooth muscle with a few exceptions (bronchial dilation).
One activity would be the acute modulation of blood pressure through contraction of vascular smooth muscle cells in the resistance vessels.
While there is some debate, sympathetics probably set the steady state heart rate with very little acute control. Acute modulation of heart rate is caused by parasympathetic stimulus and mechanical factors (Frank-Starling relationship).
Sympathetics also aid in the mobilization of metabolic energy (lipolysis, glycogenolysis).

What are the divisions of the ANS?
The autonomic nervous system (ANS) is divided into the sympathetic and parasympathetic divisions. The sympathetic division is responsible for the "fight or flight" response, increasing heart rate and pupil dilation. The parasympathetic division is involved in rest and digest functions, promoting activities like digestion and lowering heart rate.
What are the two branches of the autonomic system?
The two branches of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system. The sympathetic system is responsible for the "fight or flight" response, while the parasympathetic system is responsible for the "rest and digest" response.
What part of the brain is responsible for helping you run and catch the bus?
That part is called as hypothalamus. It is supposed to be highest centre for the autonomic nervous system. You need the sympathetic nervous system to run and catch the bus. Sympathetic nervous system is the part of the autonomic nervous system.
What endocrine gland develops from the sympathetic nervous system?
The adrenal medulla develops from the sympathetic nervous system. It is responsible for secreting hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine) in response to stress or danger.
What ramus branches that belong to the sympathetic nervous system?
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.
What division is responsible for vasomotor tone?
Sympathetic nervous system
What part of the nervous system are responsible for a heart rate of 120 bpm?
sympathetic nervous system
A person is walking through a park. A branch from a tree falls nearly hitting her. Her heartbeat speeds up. Which part of the nervous system was responsible for this?
Sympathetic Nervous System
The part of the autonomic nervous system that is responsible for reacting to stressful events and bodily arousal?
Sympathetic division or fight-or-flight system
The effects of the sympathetic nervous system are essentially opposite of which nervous system?
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
Name division of autonomic nervous system responsible for controlling ciliospinal reflex?
sympathetic
What are the divisions of the ANS?
The autonomic nervous system (ANS) is divided into the sympathetic and parasympathetic divisions. The sympathetic division is responsible for the "fight or flight" response, increasing heart rate and pupil dilation. The parasympathetic division is involved in rest and digest functions, promoting activities like digestion and lowering heart rate.
What are the two parts of the nervouse system?
The two integral parts of the autonomic nervous system are the sympathetic nervous system responsible for, "rest and digest" and the parasympathetic nervous system that is responsible for, "fight or flight".
What are the two branches of the autonomic system?
The two branches of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system. The sympathetic system is responsible for the "fight or flight" response, while the parasympathetic system is responsible for the "rest and digest" response.
How many division are there of the nervous system?
The autonomic nervous system is responsible for the control of the functions of the internal organs and it has two divisions. These are the sympathetic nervous system and the parasympathetic nervous system.
What part of the brain is responsible for helping you run and catch the bus?
That part is called as hypothalamus. It is supposed to be highest centre for the autonomic nervous system. You need the sympathetic nervous system to run and catch the bus. Sympathetic nervous system is the part of the autonomic nervous system.
What component of the nervous system is associated with the fight or flight?
sympathetic nervous system.
