Differentiate cortical from medullary nephrons.

Explanation

Cortical Nephrons :
In majority of the nephrons, the loop of Henle is too short and extends very little into the medulla i.e, they lie in the renal cortex. These are called cortical nephrons and form about 80% of total nephrons in the kidney.
Medullary Nephrons :
In some nephrons, the loop of Henle is very long and run deep into the medulla. They are called Medullary nephrons.
