Hint: A hormone secreted by certain nerve endings of the sympathetic nerve system and by the medulla (center) of the adrenal glands is called norepinephrine. Epinephrine is another term for adrenaline, it occurs naturally in the body (secreted by adrenal gland) and can also be synthetically made to be used as medication.
Complete answer:
Norepinephrine and epinephrine are known as fight or flight hormones, these hormones are released during stress state or any emergency state. Epinephrine causes contraction of smooth muscles in the arterioles, which adduct the blood vessels in the kidneys and inhibit flow to nephrons. Norepinephrine causes building of the smooth muscles in the kidneys in order to increase blood pressure. So, it inhibits the flow to nephrons.
Side effects of epinephrine
-Difficulty sleeping
-Fast heartbeat
-Headache
-Loss of appetite
-Nervousness
Side effect of norepinephrine
-Nausea and vomiting
-Shorten of breath
-High blood pressure
-Confusion for everything
Here we see that both epinephrine and norepinephrine are almost same
Thus, the correct answer is option (A).
Note:A nephron is a unit of structure and function of a kidney. They are classified into cortical nephrons and juxtamedullary nephrons. Norepinephrine is given by injecting into the vein. Epinephrine is to be used only by the patient for whom it is prescribed through epinephrine injection. Difference is in their chemical structure, norepinephrine has hydrogen. Epinephrine has a methyl group.
