(1) Juxta medullary nephrons are located in the columns of Bertini. (2) Renal corpuscle of juxta medullary

Question

Choose the correct statement given below regarding juxta medullary nephron. 

(1) Juxta medullary nephrons are located in the columns of Bertini. 

(2) Renal corpuscle of juxta medullary nephron lies in the outer portion of the renal medulla. 

(3) Loop of Henle of juxta medullary nephron runs deep into medulla. 

(4) Juxta medullary nephrons outnumber the cortical nephrons.

Answer 1

Correct option is (3) Loop of Henle of juxta medullary nephron runs deep into medulla.  

The length of loop of Henle of juxta medullary nephron is longer than the length of loop of Henle of cortical nephron and runs deep into medulla.

Option (1) is incorrect as juxta medullary nephron are not present in columns of Bertini.

Option (2) is incorrect because renal corpuscle of juxta medullary nephron lies in inner cortical region. 

Option (4) is incorrect as juxta medullary nephrons are lesser in number than cortical nephrons.
