with stimulation of the sympathetic nervous system there will be
a. constriction of the pupils
b. dilation of the coronary arteries
c. constriction of selected blood vessels
d. profuse sweating
Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.
Heart muscles has there own rhythm of contraction. The sinoatrial node has the fastest rate of contraction. That is why it governs the rhythm of the heart. You have the control of the autonomic nervous system over the heart rate. Stimulation of the sympathetic nervous system increase the heart rate. Stimulation of the parasympathetic nervous system decrease the heart rate.
Sympathetic postganglionic fibers end in effector organs such as smooth muscles, cardiac muscles, and glands. They innervate these structures to modulate their activity in response to stress or stimulation of the sympathetic nervous system.
Dilation of the bronchial tubes is increased by the sympathetic nervous system. Specifically, the release of norepinephrine from sympathetic nerve endings causes relaxation of the smooth muscle in the bronchial tubes, leading to bronchodilation.
With current technology it is not yet possible to simulate a sympathetic nervous system

The sympathetic nervous system primarily causes vasoconstriction in the body.
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.
Denoting a drug that mimics the effects of stimulation of organs and structures by the sympathetic nervous system.
A sympathomimetic drug mimics the physiological effects caused by the stimulation of the sympathetic nervous system. Note the keyword : Mimic A sympatholytic drug oppses/ blocks the physiological effects caused by stimulation of the sympathetic nervous system HOPE THIS HELPS! :)

The sympathetic nervous system causes dilation of the bronchioles. This can alleviate symptoms of an asthma attack.
End diastolic volume and sympathetic nervous system stimulation

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.
Sympathetic stimulation of the liver increases glycogenolysis and lipolysis to make energy more available to metabolic processes.
