MCQ
$A$ fall in the $GFR$ rate activates the
- ✓$JG$ cells to release reni
- B$JG$ cells to release aldosterone
- C$JG$ cells to release epinephrine
- D$JG$ cells to release nor-epinephrine
✓
Answer
Correct option: A.
$JG$ cells to release reni
a
The kidneys have built in mechanisms for the regulation of glomerular filtration rate. One such efficient mechanism is carried out by juxta glomerular apparatus $(JGA)$, $JGA$ is the special sensitive region formed by cellular modification in the distal convoluted tubule and the afferent arteriole at the location of their contact. A fall in $GFR$ can activate the $JG$ cells to release renin, which can stimulate the glomerular blood flow and there by $GFR$ back to normal
