Which autonomic neurons release norepinephrine as a neurotransmitte?
Sympathetic postganglionic neurons release norepinephrine,
What does norepinephrine do?
Norepinephrine is released from the sympathetic nervous system. Norepinephrine is a stress hormone which affects parts of the brain and causes the heart to beat more rapidly.
Preganglionic sympathetic fibers trigger the release of?
epinepherine and norepinephrine
What are norepinephrine releasing fibers called?
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
Neurotransmitter that causes an individual to feel more alert?
Acetylcholine
Norepinephrine stimulates the release of which hormone?
growth hormone
Which release norepinephrine?
The answer is sympathetic post-ganglionic axon
Do the post-ganglionic sympathetic fibers release acetylcholine?
No, post-ganglionic sympathetic fibers mostly release norepinephrine. But they do release some ACh to the sweat glands, which causes concurrent vasodilation of surrounding blood vessels (paired with release of bradykinin from sweat glands).
How does clonidine act as a sedative?
Clonidine is an alpha-2 adenergic agonist. This means that it stimulates the alpha-2 receptor. This causes a decreased release of norepinephrine and epinephrine. This decrease causes a decrease sympathetic tone acting like a sedative.
What is the medical term meaning benign tumor of the adrenal medulla that causes the gland to produce excess epinephrine and norepinephrine?
Pheochromocytoma is an adrenal tumor that results in excess epinephrine and norepinephrine
Amphetamines have stimulating effects on the nervous system because they?
release norepinephrine
Flight or fight hormone?
The fight or flight response is a physical response; a strong stimulus or emergency causes the release of a chemical called nor-adrenaline (also called norepinephrine)
