Which of the following best describes the sympathetic
pathway’s effect on the glomerulus in the kidney?
A. Sympathetic stimulation causes vasodilation of the afferent
arteriole increasing glomerular filtration rate (GFR)
B. Sympathetic stimulation causes vasoconstriction of the afferent
arteriole, decreasing glomerular filtration rate (GFR)
C. Sympathetic stimulation has no effect on the glomerulus
D. Sympathetic stimulation causes vasodilation of the efferent
arteriole decreasing glomerular filtration rate (GFR)
Ans. B
