Cortical Nephron vs. Juxtamedullary Nephron: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on January 17, 2024
Cortical nephrons are located primarily in the kidney cortex, playing a key role in filtration, while juxtamedullary nephrons extend deep into the medulla, crucial for concentrating urine.

Key Differences

Cortical nephrons have shorter loops of Henle and are mostly located in the kidney cortex, mainly involved in the filtration of blood and reabsorption of nutrients. Juxtamedullary nephrons have longer loops of Henle extending into the medulla, vital for concentrating urine and maintaining water balance.

In cortical nephrons, the loop of Henle is relatively short and does not penetrate deeply into the renal medulla, making them less involved in urine concentration. In contrast, juxtamedullary nephrons have a longer loop of Henle, reaching deep into the medulla, which is essential for producing concentrated urine.

The glomeruli of cortical nephrons are located in the outer cortex, contributing primarily to the removal of waste products and reabsorption of water and essential ions. The glomeruli of juxtamedullary nephrons are located near the cortex-medulla junction, playing a key role in the kidney's ability to concentrate urine.

Cortical nephrons make up the majority of nephrons in the human kidney and are essential for basic renal functions. Juxtamedullary nephrons, though fewer in number, are crucial for regulating the osmolarity of urine and conserving water.

Cortical nephrons are involved in glomerular filtration at a standard rate, while juxtamedullary nephrons are especially important in conditions of dehydration, where they function to conserve water and produce highly concentrated urine.
