Question

Juxta glomerular apparatus is formed by cellular modifications in 


Correct Answer
A
distal convoluted tubule and afferent arterioles
Your Answer
B
distal convoluted tubule and efferent arterioles
Your Answer
C
proximal convoluted tubule and afferent arterioles
Your Answer
D
proximal convoluted tubule and efferent arterioles

Solution

The correct option is A distal convoluted tubule and afferent arterioles
Juxta glomerular apparatus (JGA) is the specialized structure found near the glomerulus. It is formed by cellular modifications in the distal convoluted tubule and the afferent
arteriole at the location of their contact. JGA cells can secrete renin which helps in maintaining glomerular filtration rate to be 125 mL/min. A fall in glomerular rate activates JGA cells to release renin. Renin restores the glomerular filtration rate by stimulating the blood flow.
