The most common type of nephrons, which have a relatively short nephron loop that does not extend deep into the medulla, are called nephrons.

The most common type of nephrons, which have a relatively short nephron loop that does not extend deep into the medulla, are called Cortical nephrons.

Explanation:

Nephron: Nephron is the filtering & excretory structural and functional unite of kidney that filters the blood. It reabsorbs the substances such as glucose & excretes nitrogen waste from the blood such as urea & excess water and salt in the form of urine.

Cortical nephrons have their glomeruli in the outer cortex. Cortical nephrons contains shorter loop of henel which only extend into the outer region of the renal medulla. Cortical nephrons subdivide into two types:

1) Superficial cortical nephrons.

2) Midcortical nephrons.
