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
Sympathetic stimulation of terminal bronchioles causes?
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 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 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 causes the pupils to dilate in someone who is excited or frightened?
sympathetic stimulation causes the dilator muscle to contract and sphincter muscle to relax, as a result expanding the pupil.
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 sympathetic system causes bladder wall relaxation?
Yes it does relax. When the detrusor muscle, part of the bladder wall, constricts, you urinate. In a high energy situation, when sympathetic stimulation is occurring, you wouldn't want to urinate, so the wall must relax.
How does the synaptic nervous system affect the iris?
The iris is not innervated directly, however the iris sphincter muscle is affected by the sympathetic and parasympathetic nervous systems. Sympathetic stimulation causes pupil dilation while parasympathetic nervous system causes pupil constriction. The parasympathetic response is quicker because of the proximity of a parasympathetic ganglion (ciliary ganglion) to the eye. The sympathetic response is slower because all sympathetic ganglia are confined to the spinal cord. This is the reason why people adjust faster to a bright shining light than darkness.
Does adderall make your pupils big or small?
No. Adderall is a sympathomimetic, and stimulation of the sympathetic nervous system causes the pupils to dilate, not contract.
Does decreasing sympathetic stimulation decrease cardiac output?
Not necessarily. The bodies autonomous nervous system is composed of two types. Sympathetic, and parasympathetic. Also known as the fight or flight system. Sympathetic stimulation causes increased: Blood pressure, heart rate, cardiac output, faster nervous response, and heightened awareness. Stimulation of the parasympathetic nervous system causes the opposite. A heart rate that is too fast has decreased cardiac output because, to put it simply, he chambers of the heart don't have time to refill with blood to full capacity before being contracted again, thus reducing the amount of oxygenated blood being pumped with each contraction. Slowing down the sympathetic response will slow the heart rate enough to allow the chambers to fill adequately before contracting again, increasing cardiac output. In a normally beating heart, however, decreasing the sympathetic stimulation by means of a parasympathomimetic drug (which mimics the parasympathetic nervous system, will decrease cardiac output. The answer to this question is dependent on the situation.
Why do i have to pee when turned on?
It most likely is because the stimulation in your genitals also causes another stimulation of the bladder
