What is the difference between epinepherin and norepinepherin?
Epinephrine and norepinephrine are two very structurally similar molecules. They've both involved in the sympathetic part of your autonomic nervous system. Epinephrine (also known as adrenaline) is a hormone which is secreted from the adrenal medulla when activated by the sympathetic nervous system (during times of stress). Norepinephrine (also known as noradrenaline) is a neurotransmitter that is released by neurons in the sympathetic nervous system. Epinephrine and norepinephrine generally produce the same effects as they both interact with adrenergic receptors in the body. Epinephrine is structurally different from norepinephrine as epinephrine has a methyl group (-CH3) attached to the nitrogen atom (making it a secondary amine), whereas norepinephrine is just a primary amine. Image google 'norepinephrine and epinephrine' to view their chemical structures.
Why does ephedrine keep you alert?
Ephedrine is a stimulant. It is similar to amphetamine, which is also a stimulant. It increases the activity of the sympathetic nervous system, which is responsible for the "fight or flight" response.
Neurotransmitter most related to fear and arousal?
Norepinephrine (NE) is the neurotransmitter often associated with the "fight or flight" response to stress. Strongly linked to physical responses and reactions, it can increase heart rate and blood pressure as well as create a sense of panic and overwhelming fear/dread. This neurotransmitter is similar to adrenaline and is felt to set threshold levels to stimulation and arousal. Emotionally, anxiety and depression are related to norepinephrine levels in the brain, as this neurotransmitter seems to maintain the balance between agitation and depression.
What hormone is released from stimulation of the sympathetic nervous system?
Anatomically, the adrenal medulla develops from neural crest tissue, and it is directly controlled by sympathetic NS. The medullary cells respond to this stimulation by releasing epineprhrine (80%) or norepinephrine (20%), which can act in conjunction with the sympathetic NS to elicit the fight-or-flight response to stressors.epinephrine, from the adrenal medulla.Norepinephrine/Noradrenaline working with Epinephrine/Adrenalineepinephrine and norepinephrine
What hormone do CNS stimulants resemble?
The majority of CNS stimulants are chemically similar to the neurohormone norepinephrine, and simulate the traditional "fight or flight" syndrome associated with sympathetic nervous system arousal.
What natural supplements stimulate the sympathetic nervous system?
Caffeine works through similar pathways to adrenergic agonists, and has similar effects (heart rate, blood pressure increase). This is why the normal recommendation for hypertensive patients is (in part) to reduce caffeine intake.
Which gland secretes epinephrine and aldosterone?
Aldosterone is secreted by the adrenal cortex in the adrenal gland - more specifically, in the zona glomerulosa. The adrenal gland is located right above your kidneys. It's normally depicted in most images by a yellow triangular shaped object that sits atop both the left and right kidneys. Epinephrine or adrenaline is secreted by adrenal medula.
How do you know your sexually attracted?
Sexual attraction stimulates our sympathetic nervous system and produces the same kinds of physical effects as fear such as heart racing, sweaty palms, nervous butterflies, etc. If you experience symptoms similar to those it's a safe bet that you're sexually attracted to the other person.
What does mescaline stimulate the release of?
Mescaline is 3,4,5-trimethoxy-phenethylamine. Its structure is similar to the neurotransmitter dopamine and the amino acids phenethylamine and phenylalanine. Its stimulant effects come from its action on the dopaminergenic nervous system. However, its psychedelic effects arise from its action on the 5HT2A receptors of the serotonergic nervous system. In this regard, it is most likely a direct agonist of these sites.
If adrenaline is a hormone why is its effect more like those of the nervous system explain this statement?
Adrenaline (aka epinephrine) is a hormone, but bears striking resemblance to the neurotransmitters used in your nervous system. You see, your nervous system works by a series of synaptic junctions. That is, all your nerve cells are lined up from head to tail, and depolarization waves carry messages down the length of the cells. Synapases are the small gaps between each cell and the next in line. Once the depolarization wave gets to the end of the cell, it cannot just "jump the gap", but it signals the cell to release neurotransmitters. The neurotransmitters are molecules that fit like a lock and key into receptors on the next cell in line. When the neurotransmitters make contact with the receptors on the next cell, it causes a depolarization wave in that one as well, and the process goes on. In the case of the sympathetic nervous system (your fight or flight nerves), the main neurotransmitter is called norepinephrine. It is what is used in these tiny doses at the end of each nerve cell (generally). When epinephrine (adrenaline, to use the British term) is released from your adrenal gland, it travels through the blood stream and hits the same receptors that norepinephrine normally hits. It is what we call a "direct agonist response." This causes general sympathetic (fight or flight) reactions, such as bronchial dilation, increased heart rate, blood vessel dilation, capillary contraction, and pupil dilation. I wish I could draw the molecules epinephrine and norepinephrine on here, and you would be able to see how similar they are and why they would both bind to the same receptors. I suggest looking up their structures for a better idea.

parts are similar to man and working is similar also .
How are somatic and autonomic nervous systems similar?
I came on this to figure it out!
