The JGA (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in __________ related to the same nephron.
- A Distal convoluted tubule and efferent renal arteriole
- B Proximal convoluted tubule and efferent renal arteriole
- C Proximal convoluted tubule and afferent renal arteriole
- D Distal convoluted tubule and afferent renal arteriole
Answer & Solution
Correct Answer
(D) Distal convoluted tubule and afferent renal arteriole
Step-by-step Solution
Detailed explanation
(D) Distal convoluted tubule and afferent renal arteriole
The Juxta Glomerular Apparatus (JGA) is a special sensitive region formed by cellular modifications in the distal convoluted tubule (DCT) and the afferent arteriole at the location of their contact.
The cells of the DCT at this region become modified to form the macula densa, while the smooth muscle cells of the afferent arteriole are modified to form juxtaglomerular (JG) cells, which secrete renin.
