Question

Juxtaglomerular apparatus is a sensitive region formed at the location of contact of

• A. distal convoluted tubule and efferent arterioles
• B. proximal convoluted tubule and afferent arterioles
• C. proximal convoluted tubule and efferent arterioles
• D. distal convoluted tubule and afferent arterioles

Answer 1

The correct option is D distal convoluted tubule and afferent arterioles

Juxtaglomerular apparatus is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. The compact arrangement of the nephrons allows close contact between the afferent arteriole and the distal convoluted tubule.
