* Here a special apparatus called the Juxtaglomerular Apparatus has 3 different structures:
** The tubular epithelial cells of the distal tubule which are in contact with the arterioles supplying the glomerulus of that nephron are called the '''macula densa'''. They play a vital role in the [[Autoregulation of GFR - Anatomy and Physiology#Tubuloglomerular Feedback (TGF)|regulation of the GFR]].

** The Juxtaglomerular Cells are smooth muscle cells which adjoin the macula densa in the capillary wall.
