A fall in glomerular filtration rate (GFR) activities :

  • Option 1)

    adrenal cortex to release aldosterone

  • Option 2)

    adrenal medulla to release adrenaline

  • Option 3)

    posterior pituitary to release vasopressin

  • Option 4)

    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.
