Interaction between tubules and arterioles in the nephron. The tubule gets contact with afferent arteriole (AF-Art) at least in two sites: at the juxtaglomerular apparatus (JGA) (dashed line box) where the macula densa (MD) interact with the Af-Art. The JGA is the site for the tubule-glomerular feedback (TGF). The second contact between tubules and Af-Art occurs at the connecting tubule (CNT); there is the anatomical site of the connecting tubule-glomerular feedback (CTGF) (dark box).
