Juxtaglomerular cells:
A) have receptors for both antidiuretic hormone (ADH) and aldosterone.
B) are found in the macula densa.
C) are modified smooth muscle fibers (cells) in the wall of the afferent arteriole.
D) are found in the distal convoluted tubules and collecting duct.

Question

Quizplus · Accepted Answer

Juxtaglomerular cells are specialized cells in the walls of the afferent arterioles that lead into the glomeruli of the kidney. These cells are indeed modified smooth muscle fibers and play a crucial role in the regulation of blood pressure through the renin-angiotensin system. They are not located in the macula densa, nor do they have receptors for ADH or aldosterone, and they are not found in the distal convoluted tubules or collecting ducts.
