In the arteriole walls we see juxtaglomerular cells which secrete renin. ... These are tall cells that act as chemoreceptors (osmoreceptors) and respond to changes in the solute content of the filtrate in the tubule lumen. Juxtaglomerular cells - sense blood pressure.

Are JG cells mechanoreceptors?

Here, specialized smooth muscle cells of the afferent arteriole, called granular juxtaglomerular (JG) cells, act as mechanoreceptors that monitor blood pressure in the afferent arteriole. ... Together, these cells help regulate blood pressure and the production of urine in the nephron.

Is macula densa a Chemoreceptor?

Macula densa cells are chemoreceptors that can sense when glomerular filtration rate increases or decreases based on the quantity of sodium and chloride ions flowing through the tubule.
