Bronchodilation.
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.
sympathetic system
The sympathetic nervous system causes dilation of the bronchioles. This can alleviate symptoms of an asthma attack.
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 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.
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.
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.
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.
No, dilation of the trachea and bronchioles is typically caused by the sympathetic nervous system, which leads to relaxation of smooth muscles in the airways. Parasympathetic activity usually causes constriction of the airways.
