2024 Excretory Products and their EliminationJuxtamedullary Nephrons Medium Question 6 of 60 in Excretory Products and their Elimination

Choose the correct statement given below regarding juxta medullary nephron.

A Loop of Henle of juxtamedullary nephron runs deep into medulla.
B Juxtamedullary nephrons outnumber the cortical nephrons.
C Juxtamedullary nephrons are located in the columns of Bertini.
D Renal corpuscle of juxtamedullary nephron lies in the outer portion of the renal medulla.

The answer is A.

Solution

In juxtamedullary nephrons, the loop of Henle is very long and runs deep into the medulla – correct. Juxtamedullary nephrons are fewer in number than cortical nephrons, they are not located in the columns of Bertini, and their renal corpuscles lie in the inner cortical region (not in the medulla).
