Juxtaglomerular (JG) cells are specialized cells located in the kidneys, specifically in the afferent arterioles (blood vessels leading to the glomeruli). They play a crucial role in regulating blood pressure and the filtration rate of the kidneys by secreting the enzyme renin.
Pathophysiology
Structure
JG cells are modified smooth muscle cells situated near the glomerulus, the tiny blood vessel network where blood filtration begins. They are part of the juxtaglomerular apparatus, which includes the macula densa cells and the mesangial cells.
Blood Supply
These cells receive blood through the afferent and efferent arterioles. Adequate blood flow is essential for their function in monitoring and regulating kidney activities.
Nerve Supply
JG cells are innervated by the sympathetic nervous system, which influences their secretion of renin in response to various stimuli like blood pressure changes.
While JG cells are a specific type of cell within the kidney, variations can occur based on their functional state, such as resting or activated states during renin secretion.

Kidney Stones
Description and Definitions
Kidney stones are hard mineral and salt deposits that form inside the kidneys. They can affect any part of the urinary tract and vary in size. Kidney stones can be extremely painful and may require medical treatment.
