A fall in glomerular filtration rate (GFR) activities :
adrenal cortex to release aldosterone
adrenal medulla to release adrenaline
posterior pituitary to release vasopressin
juxta glomerular cells to release rennin
As we discussed in concept
Mechanisms for the regulation of glomerular filtration rate -
Mechanism is carried out by juxta glomerular apparatus (JGA).
- wherein
JGA is a special sensitive region formed by cellular modifications 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 thereby the GFR back to normal.
GFR can activate the JG cells to release renin.
Option 1)
adrenal cortex to release aldosterone
This option is incorrect.
Option 2)
adrenal medulla to release adrenaline
This option is incorrect.
Option 3)
posterior pituitary to release vasopressin
This option is incorrect.
Option 4)
juxta glomerular cells to release rennin
This option is correct.
