The JGA (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in ____________ related to the same nephron.
Options
- ADistal convoluted tubule and efferent renal arteriole
- BProximal convoluted tubule and efferent renal arteriole
- CProximal convoluted tubule and afferent renal arteriole
- DDistal convoluted tubule and afferent renal arteriole
Correct answer
D. Distal convoluted tubule and afferent renal arteriole
Step-by-step solution
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.
Answer: Distal convoluted tubule and afferent renal arteriole
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.
Answer: Distal convoluted tubule and afferent renal arteriole
