Question

At the start of today's exam, your sympathetic activity was likely elevated, what are the physiological ramifications of that?

Select one:

a. The pressure differential between the arteries and veins would be decreased

b. Your glomerular filtration rate would be higher

c. Norepinephrine would preferentially bind to beta-receptors in the heart

d. Reduced coronary myocyte oxygen use

e. None of the above

e. None of the above

During sympathetic stimulation, the digestion and urine formation decreases. The cardiac output and blood pressure increases after sympathetic stimulation. The cardiac stimulation occurs due to preferential binding of norepinephrine to the beta-adrenergic receptors in the heart.
