Answer:
The correct answer will be- Juxtaglomerular cells or the granular cells
Explanation:
In the juxtaglomerular apparatus which is formed by the distal convoluted tubule and the glomerular afferent tubule contains specialized epithelial cells which detect the concentration of the sodium ions in the fluid and contract the afferent arteriole.
The juxtaglomerular cells are derived from the smooth muscle cells of the afferent arterioles present adjacent to the macula dense which is involved in the production of the renin when the blood pressure falls and thus increases the blood pressure.
Thus, Juxtaglomerular cells are the correct answer.
