Anatomical terminology |
Juxtaglomerular cells (JG cells), also known as juxtaglomerular granular cells are
Juxtaglomerular cells secrete renin in response to a drop in pressure detected by stretch receptors in the vascular walls, or when stimulated by macula densa cells. Macula densa cells are located in the distal convoluted tubule, and stimulate juxtaglomerular cells to release renin when they detect a drop in chloride concentration in tubular fluid. Together, juxtaglomerular cells, extraglomerular mesangial cells and macula densa cells comprise the juxtaglomerular apparatus.
In appropriately stained tissue sections, juxtaglomerular cells are distinguished by their granulated cytoplasm.
The juxtaglomerular cell is a cell that is located near the glomerulus, hence its name.
Similar to cardiac tissue, juxtaglomerular cells harbor
