Uberon definition : An anatomical structure which consists of juxtaglomerular cells, extraglomerular mesangial
cells and the macula densa. The juxtaglomerular apparatus lies adjacent to the glomerulus
and regulates kidney function by maintaining the blood flow to the kidney and the
filtration rate[GO]. a microscopic structure in the kidney, which regulates the function
of each nephron. The juxtaglomerular apparatus is named for its proximity to the glomerulus:
it is found between the vascular pole of the renal corpuscle and the returning distal
convoluted tubule of the same nephron. This location is critical to its function in
regulating renal blood flow and glomerular filtration rate. The three cellular components
of the apparatus are the macula densa, extraglomerular mesangial cells, and juxtaglomerular
cells (also known as granular cells)[WP].;
