The juxtaglomerular apparatus is named because it is next to the glomerulus. The functional entity in the kidney that consists of juxtaglomerular cells (epithelioid cells in the media of the afferent arterioles) and the macula densa (tubular epithelium at the region of afferent arteriole and efferent arteriole to the glomerulus), and is involved in the regulation of salt and water excretion and renal blood flow. Special concern to demonstrate the association between.

The juxtaglomerular cell is a cell that is located near the glomerulus, hence its name.
Two types of contact between vascular and tubular components are observed: The juxtaglomerular apparatus also known as the juxtaglomerular complex, is a structure in the kidney that regulates the function of each nephron, the functional units of the kidney. B) afferent arteriole is in contact with the distal tubule. juxtaglomerular apparatus (jga) a region of tissue found in each nephron in the kidney that is important is regulating blood pressure and body fluid and electrolytes.it is located where the distal convoluted tubule passes close to the afferent arteriole supplying the bowman's capsule, near to the glomerulus, and contains two types of specialized cells.
