Difference Between Cortical Nephron and Juxtamedullary Nephron

Cortical nephrons have a short loop of Henle, which penetrates only the outer renal medulla. Juxtamedullary nephrons have a long loop of Henle extending deep into the renal medulla. ... The juxtamedullary nephrons concentrate or dilute urine.

What is the difference between cortical and Juxtamedullary nephrons?

Cortical nephrons have a glomerulus located nearer to the outer parts of the cortex and their loops of Henle are short. Juxtamedullary nephrons have a glomerulus near the junction of the cortex and medulla and their loops of Henle penetrate deep into the medulla.

What is the role of the cortical vs Juxtaglomerular nephrons?

Cortical nephrons are mainly involved in the excretory and regulatory functions of the body while juxtamedullary nephrons concentrate or dilute urine. Thus, the main difference between cortical nephron and juxtamedullary nephron is their structure and function.

What is the difference between the two types of nephrons?

There are two types of nephrons: Superficial cortical nephrons, which have their glomeruli in the outer cortex. They have shorter loops of Henle, which dip only into the outer medulla. ... Juxtamedullary nephrons, which have their glomeruli near the corticomedullary border.

What is the function of the Juxtamedullary nephron?

Although both cortical and juxtamedullary nephrons regulate the concentrations of solutes and water in the blood, countercurrent multiplication in the loops of Henle of juxtamedullary nephrons is largely responsible for developing the osmotic gradients that are needed to concentrate urine.

What are the 5 major parts of the cortical nephron?

The tubule has five anatomically and functionally different parts: the proximal tubule, which has a convoluted section the proximal convoluted tubule followed by a straight section (proximal straight tubule); the loop of Henle, which has two parts, the descending loop of Henle ("descending loop") and the ascending loop ...

Why is Vasa recta absent in cortical nephron?

The proximity between the Henle's loop and vasa recta, as well as the counter current in them help in maintaining an increasing osmolarity towards the inner medullary interstitium. This gradient is mainly caused by NaCl and urea.

What is the function of cortical nephrons?

About 85% of the nephrons in the human kidney are cortical, and about 15% – juxtamedullary. The major part of the regulatory and excretory functions of the human body is carried out by the cortical nephrons. The juxtamedullary nephrons concentrate or dilute urine.

Is Vasa recta present in cortical nephron?

Vasa recta is well developed in cortical nephrons.

How are the nephrons arranged in the kidney?

At one end of each nephron, in the cortex of the kidney, is a cup-shaped structure called the Bowman's capsule. It surrounds a tuft of capillaries called the glomerulus that carries blood from the renal arteries into the nephron, where plasma is filtered through the capsule.

What are the parts of nephron?

Each nephron is composed of a renal corpuscle (glomerulus within Bowman's capsule), a proximal tubule (convoluted and straight components), an intermediate tubule (loop of Henle), a distal convoluted tubule, a connecting tubule, and cortical, outer medullary, and inner medullary collecting ducts.

What are the major steps in urine formation in a nephron?

There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body.

How many types of nephron are there?

There are two types of nephrons— cortical nephrons (85 percent), which are deep in the renal cortex, and juxtamedullary nephrons (15 percent), which lie in the renal cortex close to the renal medulla.
