vascular pole

The vascular pole is a location of the glomerulus.

The vascular pole is where the afferent and efferent arterioles communicate with the glomerulus.

The urinary pole is a location on the renal corpuscle opposite to the vascular pole.

There are two poles in the renal corpuscle, a vascular pole, and a urinary pole.

At the vascular pole, the afferent arterioles and efferent arterioles enter the Bowman's capsule.

Polkissen cells aka juxtaglomerular cells are located between the afferent and efferent arterioles at the vascular pole of the glomerulus, adjacent to the macula densa.

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.

Extraglomerular mesangial cells (also known as Lacis cells, Goormaghtigh cells, or Polkissen cells) are light-staining cells in the kidney found outside the glomerulus, near the vascular pole and macula densa.

In the kidney, the macula densa is an area of closely packed specialized cells lining the wall of the distal tubule at the point of return of the nephron to the vascular pole of its parent glomerulus, (glomerular vascular pole).
