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 increases Sympathetic stimulation?
Sympathetic stimulation can be increased by various factors, including physical stressors like exercise, emotional stress, and perceived threats. Hormonal responses, particularly the release of adrenaline (epinephrine) from the adrenal medulla, also enhance sympathetic activity. Additionally, certain medications and stimulants, such as caffeine, can elevate sympathetic stimulation by affecting neurotransmitter release and receptor activity.
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.
Does coronary vessels have both parasympathetic and sympathetic innervation?
Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.
What does sympathetic stimulation mean?
The sympathetic portion of the autonomic system is activated. You activate what is called the Fight or Flight system. Your heart beat increases as well as your blood pressure.
What does preganglionic sympathetic Stimulation produce?
ACH
Sympathetic stimulation of terminal bronchioles causes?
Bronchodilation.
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.
Does the heart receive both parasympathetic and sympathetic stimulation?
yes

What is sympathetic stimulation?
Sympathetic stimulations are signals to the body that imply stress. Sympathetic stimulation stimulates the sympathetic part of the peripheral nervous system and results in multiple response such as increased cardiac output, dilation of the pupil, inhibition of the smooth muscles of the gastrointestinal tract and urinary bladder, and erection of the penis.
What happens if the heart receives more sympathetic stimulation than parasympathetic stimulation?
increase its rate and force of contraction
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
The effects of sympathetic and parasympathetic stimulation of the salivary glands are called?
complementary
True or false Sympathetic stimulation of the lung results in broncoconstriction?
false
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 is the effect of sympathetic stimulation on the rectum?
Sympathetic stimulation causes relaxation of the rectum's smooth muscle, leading to decreased motility and tone. This can result in decreased urgency and the ability to retain feces.
