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. The juxtaglomerular apparatus is named because it is next to (juxta- [1]) the glomerulus. The juxtaglomerular apparatus consists of three types of cells:

2024年4月15日 · The juxtaglomerular apparatus (JGA), also referred to as the juxtaglomerular complex, is a specialized region of the nephron formed by three different types of cells: macula densa, juxtaglomerular granular, and extraglomerular mesangial (Lacis) cells.

However, as considered below, salt- sensing and the regulation of salt excretion is provided mainly via tubuloglomerular feedback (TGF) in the juxtaglomerular apparatus (JGA) consisting of macula...

It has a plaque shape consisting of 35-40 polarized cells (Lorenzi et al., 2020), strategically placed in the juxtaglomerular apparatus (JGA) (Cangiotti et al., 2018).

Our study analyzed the expression pattern of different connexins (Cxs) and renin positive cells in the juxtaglomerular apparatus (JGA) of developing, postnatal healthy human kidneys and in ...

2020年7月6日 · The document summarizes the juxtaglomerular apparatus (JGA) and tubuloglomerular feedback mechanism. The JGA is located near the glomerulus and is formed by macula densa cells, extraglomerular mesangial cells, and juxtaglomerular cells. The primary function of the JGA is secretion of hormones like renin and prostaglandins.

2005年7月19日 · Tutorial of flow-diagram model of JGA physiology Juxtaglomerular Apparatus This is a region where, in each nephron, the distal convoluted tubule touches the afferent arteriole.

The juxtaglomerular apparatus (JGA) controls the rate of the glomerular blood flow depending on various factors such as hydration, blood volume and ion concentration. The JGA includes the macula densa and juxtaglomerular cells. The macula densa is a short segment of the distal convoluted tubule that is located directly adjacent to the afferent ...

The juxtaglomerular apparatus (JGA) is a composite assembly of specialized structures at the vascular pole of the glomerulus (Figures 20.28 and 20.29). The thick ascending limb of Henle's loop (TAL) returns to its parent glomerulus and extends through the angle between afferent and efferent arterioles, where it is firmly attached to the ...

2014年10月18日 · The document summarizes the juxtaglomerular apparatus (JGA) and tubuloglomerular feedback mechanism. The JGA is located near the glomerulus and is formed by macula densa cells, extraglomerular mesangial cells, and juxtaglomerular cells. The primary function of the JGA is secretion of hormones like renin and prostaglandins.
