Does the effect of epinephrine mimic the effect of the sympathetic nervous system or the parasympathetic 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.
Does epinephrine increase afterload?
Yes, epinephrine can increase afterload. It does this by causing vasoconstriction of peripheral blood vessels through its action on alpha-adrenergic receptors, which raises systemic vascular resistance. Additionally, epinephrine stimulates the heart to contract more forcefully and increases heart rate, contributing to a higher cardiac output, but the increased vascular resistance primarily affects afterload.
Is epinephrine converted to nor epinephrine in the sympathetic system?
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
What are drugs that mimic the sympathetic nervous system?
norepinephrine/noradrenaline working in tandem with epinephrine/adrenaline
Epinephrine has an affinity to what recepotor?
Epinephrine has an affinity for adrenergic receptors, particularly alpha and beta adrenergic receptors in the sympathetic nervous system.
What effect does serotonin have on the vascular system?
effect of serotonin in vascular system
Does the effect of epinephrine mimic the effect of the sympathetic nervous system or the parasympathetic nervous system?

What hormone causes vasodilation of the blood vessels?
Epinephrine can cause vasodilation provided the level is low enough. If beta-2 recptors are activated (without the level of epinephrine being high enough to involve the significant numbers of alpha receptors), then the effect of epinephrine on the vascular smooth muscle be relaxation, thus, dilation. However, higher levels of epinephrine will activate alpha receptors which will cause vasoconstriction.
Does epinephrine have a glucose-sparing effect?
no
Who Activates the sympathetic nervous system?
epinephrine and norepinephrine stimulate the sympathetic nervous system
Does epinephrine increase afterload?
Yes, epinephrine can increase afterload.

Additionally, epinephrine stimulates the heart to contract more forcefully and increases heart rate, contributing to a higher cardiac output, but the increased vascular resistance primarily affects afterload.
Which division of the autonomic nervous system does epinephrine imitate?
The sympathetic (fight or flight) system.
How long do the side effects of epinephrine last?
hoe long does epinephrine last in the system after injection?
Is epinephrine converted to nor epinephrine in the sympathetic system?
Yes, epinephrine is converted to norepinephrine in the sympathetic nervous system by the enzyme phenylethanolamine N-methyltransferase (PNMT), which is found in the adrenal medulla. Norepinephrine acts as a neurotransmitter in the sympathetic nervous system.
What kinds of plant have structures that move water and other substances?
vascular
What is the major difference between the vascular system of a human and a starfish?
The major difference between the vascular system of a human and a starfish is that humans have cardio vascular system and starfish have water vascular system.
What are drugs that mimic the sympathetic nervous system?
norepinephrine/noradrenaline working in tandem with epinephrine/adrenaline
