The effect of epinephrine mimics the effect of the sympathetic nervous system. Epinephrine is also known as adrenaline, and it activates the "fight or flight" responses in the body, such as increasing heart rate, dilating airways, and increasing blood flow to muscles.
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.

Epinephrine and norepinephrine (also known as adrenaline and noradrenaline) are hormones that increase and prolong the effects of the sympathetic nervous system. They are released from the adrenal glands during the "fight or flight" response to stress and help prepare the body for action by increasing heart rate, blood pressure, and energy availability.
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
"Adrenergic" refers to the physiological effects resulting from the activation of the body's adrenergic receptors by the neurotransmitter epinephrine (adrenaline) or norepinephrine. These effects typically involve the fight-or-flight response, which increases heart rate, blood pressure, and energy levels to prepare the body for a perceived threat.
When the sympathetic division of the autonomic nervous system us activated its effects can be prolonged by the secretions of the epinephrine by the adrenal medulla. Adrenal medulla is the inner most part of the adrenal gland.Ê
An agent that mimics the effects of the sympathetic nervous system.Example: Epinephrine and norepinephrine are sympathomimetic hormones because they produce effects that mimic those brought about by the sympathetic nervous system.
The effect of epinephrine mimics the effect of the sympathetic nervous system. Epinephrine is also known as adrenaline, and it activates the "fight or flight" responses in the body, such as increasing heart rate, dilating airways, and increasing blood flow to muscles.
Antiadrenergic drugs decrease or block effects of sympathetic nerve stimulation, endogenous catecholamines (e.g. epinephrine), and adrenergic drugs.

Because it causes less cardiovascular side effects than common epinephrine
tachycardia and possible dizziness
The secretion of the adrenal medulla acts to supplement the effects of the sympathetic nervous system by releasing hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones help prepare the body for fight or flight responses by increasing heart rate, dilating airways, and redirecting blood flow to essential organs.
