Juxtaglomerular apparatus lies in relation to ?

GlomerulusAs the name implies ju.aglomerulus apparatus (JGA) lies at hilum of glomerulus Juxtaglornerulus apparatus The three microscopic components of the apparatus are the macula densa, extraglomerular mesangial cells (lacis cells), and juxtaglomerular cells.Juxtaglomerular cellJuxtaglomerular cells (JG cells, also known as granular cells) are the site of renin secretion.Macula densaAt the point where the afferent aeriole enters the glomerulus and the efferent leaves it, the tubule of the nephron touches the aeriole of the glomerulus from which it arose.At this location, which marks the sta of the distal convulation, there is the modified region of tubular epithelium called the macula densa
