The sodium-sensing cells of the glomerulus are called the:
A) podocytes.
B) macula densa.
C) mesangial cells.
D) loop of Henle.

Question

Quizplus · Accepted Answer

The macula densa cells are located in the distal convoluted tubule of the nephron, next to the afferent arteriole. These cells monitor the sodium concentration in the filtrate and signal the juxtaglomerular cells to release renin if the sodium concentration is too low. The podocytes are specialized cells that form part of the filtration barrier in the glomerulus. Mesangial cells provide support to the glomerular capillaries and help regulate blood flow. The loop of Henle is a section of the nephron that plays a role in creating a concentration gradient in the kidney.
