What Is The Difference Between Juxtamedullary And Cortical Nephron?

What are the two main types of nephrons?

There are two types of nephron, those with long Henle’s loops and those with short loops.

Short loops turn back in the outer medulla or even in the cortex (cortical loops).

Long loops turn back at successive levels of the inner medulla..

Where is the Vasa recta found in the kidney?

In the blood supply of the kidney, the vasa recta renis (or straight arteries of kidney, or straight arterioles of kidney) form a series of straight capillaries in the medulla. They lie parallel to the loop of Henle.

What is the order of a nephron?

The functional unit of the kidney, the nephron, consists of the renal corpuscle, PCT, loop of Henle, and DCT.

How many capillary beds are associated with a Juxtamedullary nephron?

two capillary bedsThe renal tubule of every nephron is closely associated with two capillary beds: the glomerulus and the peritubular capillaries.

Which structure is absent or highly reduced in cortical nephrons?

Vasa rectaVasa recta is absent or highly reduced in cortical nephrons.

What is the difference between cortical nephron and Juxtamedullary nephron?

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 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’ loops of Henle dip deeper into the inner medulla and papilla, and are vital in the concentration of urine.

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. … This mechanism helps to maintain a concentration gradient in the medullary interstitium.

What is the cortical nephron?

What is Cortical Nephron? Cortical nephron is a microscopic structural and functional unit of the kidney with a short loop of Henle, which penetrates only the outer renal medulla. The Malpighian corpuscles of these nephrons are located in the outer part of the renal cortex. Cortical nephrons occur in all vertebrates.

Is Vasa recta same as peritubular capillaries?

The main difference between vasa recta and peritubular capillaries is that the vasa recta are the blood capillaries that surround the loop of Henle in the juxtamedullary nephrons. But, peritubular capillaries are the blood capillaries that surround the PCT and DCT of the cortical nephrons.

What is Juxtaglomerular nephron?

The juxtaglomerular apparatus (also known as the juxtaglomerular complex) is a structure in the kidney that regulates the function of each nephron, the functional units of the kidney. The juxtaglomerular apparatus is named because it is next to (juxta-) the glomerulus.

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 …

Where is the cortical nephron located?

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.

Where are most nephrons located?

The nephron is the functional unit of the kidney. The glomerulus and convoluted tubules of the nephron are located in the cortex of the kidney, while the collecting ducts are located in the pyramids of the kidney’s medulla.
