Question

Which of the following is correct with respect to the juxtamedullary nephron?

• A. Henle’s loop is long
• B. Henle's loop extends deep into the medulla
• C. Both a & b are correct
• D. Henle's loop is short

Answer 1

The correct option is C Both a & b are correct

Nephron is the functional unit of the kidney. In some of the nephrons, the loop of Henle is very long and runs deep into the medulla. These nephrons are called juxta medullary nephrons.

In majority of nephrons, the loop of Henle is too short and extends only very little into the medulla. Such nephrons are called cortical nephrons
