Sympathetic stimulation causes
A) mesangial cells to release angiotensin, which ultimately leads to granular cell contraction.
B) mesangial cells to release angiotensin, which ultimately leads to granular cell relaxation.
C) granular cells to release renin, which ultimately leads to mesangial cell contraction.
D) granular cells to release renin, which ultimately leads to mesangial cell relaxation.
E) inhibited release of erythropoietin and contraction of granular and mesangial cells.

Question

Quizplus · Accepted Answer

Sympathetic stimulation causes granular cells in the kidneys to release renin, which is part of the renin-angiotensin-aldosterone system (RAAS). This system ultimately leads to the contraction of mesangial cells, affecting the filtration rate in the kidneys.
