Question

On the basis of location, juxtamedullary nephrons and cortical nephrons are the two types of nephrons. Which of the following is true about cortical nephrons?

• A. Their glomeruli lie close to the inner margin of the cortex
• B. They are about $85\%$ of the total nephrons
• C. Their loops of Henle are very long and extend deep into the medulla
• D. They control plasma volume when water supply is short

Answer 1

The correct option is B They are about $85\%$ of the total nephrons

B is the correct option as this is true statement about cortical nephrons. They are about $85\%$ of the total nephrons.

Their glomeruli lie close to the outer margin of the cortex, their loops of Henle are short and they control plasma volume when water supply is more.
