NEET 2026 (Phase 1) · BiologyPrevious Year Question
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✓
Correct Answer
(D) Distal convoluted tubule and afferent renal arteriole
Solution & Explanation
Answer: (D) Distal convoluted tubule and afferent renal arteriole. Solution: The juxta glomerular apparatus (JGA) is a special sensitive region of the nephron formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. It is not formed by the PCT or the efferent arteriole. Hence the correct pair is DCT and afferent arteriole. NCERT Reference: Ch 16, p.209, line(s) 7-10 — "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."
