d. profuse sweating
What else can I help you with?
Sympathetic division stimulation causes?
Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure.
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.
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.
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 direct neural stimulation through the sympathetic division promote many metabolic effects via hormone release?
True
What is the result of sympathetic stimulation on the trachea?
Sympathetic stimulation of the trachea causes the trachealis muscle to relax, giving the trachea a large cross-sectional area. This allows increased air flow because of the increased diameter and less resistance.
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.
What will sympathetic stimulation of the eye do?
Sympathetic stimulation of the eye will cause dilation of the pupil (mydriasis) and relaxation of the ciliary muscle for far vision.
Are the rami communicantes associated with the sympathetic or parasympathetic division?
Sympathetic Division.
What does preganglionic sympathetic Stimulation produce?
ACH
Is dilation of the pupil a function of the sympathetic division?
Yes, dilation of the pupil is primarily controlled by the sympathetic division of the autonomic nervous system. When the sympathetic system is activated, it causes the pupil to dilate, allowing more light to enter the eye.
