Does the sympathetic nervous system primarily cause vasodilation or vasoconstriction in the body?
The sympathetic nervous system primarily causes vasoconstriction in the body.
Does the sympathetic system cause vasodilation?
Yes, the sympathetic nervous system can cause vasodilation in certain situations, such as during exercise or in response to stress. This is because the sympathetic system releases certain neurotransmitters that can relax blood vessels and increase blood flow to muscles and other tissues.
Does sympathetic activity cause vasodilation?
No, sympathetic activity typically causes vasoconstriction, not vasodilation.
What are the effectors that cause vasodilation and vasoconstriction?
Vasodilation is primarily caused by factors like nitric oxide, prostaglandins, and certain medications like calcium channel blockers. On the other hand, vasoconstriction is mainly brought about by substances such as endothelin, angiotensin II, and sympathetic nervous system activation through norepinephrine release.
How does sympathetic activation affect blood vessel diameter, leading to either vasodilation or vasoconstriction?
Sympathetic activation can cause blood vessels to either dilate (vasodilation) or constrict (vasoconstriction) by releasing neurotransmitters that bind to receptors on the blood vessel walls. When the sympathetic nervous system is activated, it releases norepinephrine, which can bind to alpha-adrenergic receptors on blood vessels, causing them to constrict and decrease blood flow. Alternatively, the release of epinephrine can bind to beta-adrenergic receptors, leading to vasodilation and an increase in blood flow.

Does the sympathetic nervous system cause vasoconstriction?
Yep! The sympathetic nervous system causes both vasoconstriction & vasodilation. During "fight or flight" you need more O2/blood delivered to your skeletal muscles. The SNS causes vasodilation in skeletal muscles. The other organs, of the body (like digestive organs) are not needed for "fight or flight" survival. The SNS causes vasoconstriction in these organs.
Does sympathetic stimulation cause vasodilation of which arterioles?
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.

What would cause vasoldilation of arterioles?
decreased activity of the sympathetic nervous system
How does an increase in sympathetic nervous system activity affect blood pressure?
An increase in sympathetic nervous system activity can lead to higher blood pressure. This is because the sympathetic nervous system releases hormones like adrenaline, which can cause blood vessels to constrict and the heart to beat faster, resulting in elevated blood pressure.
What is the role of vasodilation?
vasodilation is controlled by the nervous system as well as renal system and cardiovascular system.vasodilation cause increase heat production. and feel more warmthvasodilation cause blood pressure is low and client under go hypotensive state.vasodilation also affect the nervous system . it will produce synccope when suddenly vasodilationit cause increase capillary blood that affect the hair growth in alopecia case
What kind of stimulus might cause a reponse from your autonomic system?
The autonomic nervous system is in charge of involuntary functions. There are two divisions-the sympathetic and parasympathetic. The sympathetic nervous system initiates the fight-or-flight response in emergency situations. The parasympathetic nervous system is referred to as the "rest and digest" stage in which the body "slows down" after the fight-or-flight response.
Which of these endocrine glands produce hormones that work with the sympathetic nervous system and cause the fight or flight response?
adrenal glands!
