Question

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

• A. Henle’s loop extends deep into the medulla
• B. Henle's loop extends very little into the medulla
• C. Majority of them are cortical nephrons
• D. Both b and c

Answer 1

The correct option is D Both b and c

Nephron is the functional unit of the kidney. There are two types of nephrons - cortical and juxtamedullary nephrons.
In the majority of nephrons, the loop of Henle is short and extends only very little into the medulla. Such nephrons are called cortical nephrons.
In a few nephrons the Henle's loop extends deep into the medulla such nephrons are called juxtamedullary nephrons.
