Answer to Question 1

ANS: C
The baroreceptors are located in the aortic arch of the heart.
The baroreceptors are not located in the brachial artery, the adrenal glands, or the renal glomerulus.

Answer to Question 2

ANS: D
A sympathetic antagonist would block the effects of the sympathetic nervous system and, as a result, lower the heart rate.
A sympathomimetic results in an increase in the heart rate, because it produces a mimicking of the sympathetic nervous system.
A parasympathetic antagonist blocks the effects of the parasympathetic nervous system, thus increasing the heart rate.
A parasympathetic inhibitor would also block the effects of the parasympathetic nervous system, thus increasing the heart rate.
