In general Autonomic tone of peripheral blood vessels increase when?
sympathetic stimulation is increased.
Sympathetic division stimulation causes?
Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure.
What is the effect on blood pressure to an attack by a mugger?
Blood pressure would increase due to sympathetic nervous system stimulation.
What does epinephrine do to the blood vessels?
Sympathetic stimulation (I'm guessing you mean your bodie's reaction in fight or flight) makes the blood vessles tighten, or constrict, hightening blood pressure. This is bad for you over long periods of time.
Does coronary vessels have both parasympathetic and sympathetic innervation?
Yes. Sympathetic nerve stimulation dilates the blood vessels. Parasympathetic nerve stimulation constricts the blood vessels. The sympathetic nerve stimulation effect is more pronounced.
Sympathetic nervous system stimulation causes what?
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 stimulation raise blood sugar?
No sypathetic nervous system does not raise blood sugar. It decreaces blood sugar concentration by providing that sugar(glucose) as an energy source to muscles which are under fight or flight response.
What is the sympathetic effect on the heart?
Heart rate increases with sympathetic nervous system. There is increase in stroke volume and cardiac output. With stimulation of vagus nerve or parasympathetic nervous system, You have decrease in heart rate. There is decrease the stroke volume and cardiac output.
Autonomic tone of peripheral blood vessels would be greatest when?
When sympathetic stimulation is increased.
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
Drugs that increase heart rate blood pressure and breathing rate are?
Atropine increases the heart rate by increasing the sympathetic nerve stimulation while propanalol decreases the heart rate by decreasing the parasympathetic nerve stimulation.
What best demonstrates an example of cooperation of the parasympathetic and sympathetic nervous systems?
The best example of cooperative autonomic effects is seen in controls of the external genitalia. Parasympathetic stimulation causes vasodilation of blood vessels in the external genitalia, and is responsible for erection of the male penis or female clitoris during sexual excitement. Sympathetic stimulation then causes the ejaculation of semen by the penis or reflex contractions of the vagina during an orgasm.
