b. dilation of the coronary arteries
c. constriction of selected blood vessels
d. profuse sweating
What else can I help you with?
How do the kidneys react to sympathetic nervous system stimulation?
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.
Heartbeat is governed by what body system?
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.
Where do sympathetic postganglionic fibers end?
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.
How might you feel when your sympathetic nervous system is simulated?
With current technology it is not yet possible to simulate a sympathetic nervous system
Dilation of the bronchial tubes is increased by the part of the autonomic nervous system called?
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.
How do the kidneys react to sympathetic nervous system stimulation?
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.
What causes sympathetic division stimulation?
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
Does the sympathetic nervous system primarily cause vasodilation or vasoconstriction in the body?
The sympathetic nervous system primarily causes vasoconstriction in the body.
What system controls the flow of saliva?
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.
What is a Sympathomimetic?
Denoting a drug that mimics the effects of stimulation of organs and structures by the sympathetic nervous system.
What is the difference between sympathomimetic and sympatholytic drugs?
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! :)
What part of his nervous system causes his heart to race?
sympathetic. Apex
How might mimicking the the sympathetic nervous system help alleviate an asthma attack?
The sympathetic nervous system causes dilation of the bronchioles. This can alleviate symptoms of an asthma attack.
What two mechanisms influence the force of cardiac contraction?
End diastolic volume and sympathetic nervous system stimulation
Which part of the nervous system causes dry mouth and dilates bronchioles?
sympathetic system
How does the liver respond to sympathetic nervous system arousal?
Sympathetic stimulation of the liver increases glycogenolysis and lipolysis to make energy more available to metabolic processes.
What component of the nervous system is associated with the fight or flight?
sympathetic nervous system.
