How do cortical nephrons and juxtamedullary nephrons differ structurally?
The cortical nephrons,from their name are almost entirely embedded within the cortex of the kidney.They have shortish loops of Henle that do not really extend far into the medulla. By contrast, the juxtamedullary nephrons have longs loops of Henle that do extend far into the medulla.The glomeruli of the juxtamedullary nephrons are typically close to the medulla (which is how these got their name)

What are the different types of nephrons?
Juxtamedullary Nephron: renal corpuscles close to the base of renal medulla (long loop of Henle and long thin segments that extends in the inner region of renal pyramid) Coritcal Nephron: renal corpuscles in the outer part of the renal cortex (short loop of Henle and hairpin turn in the thick segment) Intermediate Nephron: renal corpuscles in the mid-region of renal cortex (intermediate lenght loop of Henle)
What is the function of juxtamedullary nephron?
Juxtamedullary nephrons are involved in the concentration of urine by creating a concentration gradient in the kidney medulla. They have longer loops of Henle that extend deep into the medulla, allowing for increased reabsorption of water and production of concentrated urine. These nephrons play a crucial role in maintaining water balance and conserving body fluids.
Is the juxtamedullary nephron located closer to the renal medulla?
Yes, the juxtamedullary nephron is located closer to the renal medulla compared to the cortical nephron. It has a longer loop of Henle that extends deep into the medulla, allowing for concentration of urine and regulation of water balance.
What is the purpose of the juxtamedullary nephrons?
Juxtamedullary nephrons are positioned close to the medulla of the kidney and play a crucial role in concentrating urine. They have long loop of Henle which allows for the reabsorption of water and solutes, helping the body to maintain water balance and excrete waste efficiently.
What is cortical nephrons?
the cortical nephron is another type of nephron which has shorter loop of henle extended in medulla region. it has no proper function but it works like as ultra filtration etc as juxta medullary nephron perform but juxta medullary has proper function.
Nephrons located close to the medulla with loops of henle that extend deep into the renal pyramids are called?
These nephrons are called juxtamedullary nephrons. They play a key role in establishing concentration gradients in the kidney that are necessary for water reabsorption and urine concentration.
Which Nephrons have a long loop of Henle?
Juxtamedullary nephrons have a long loop of Henle, which extends deep into the medulla of the kidney. These nephrons play a crucial role in concentrating urine by creating a hypertonic medullary interstitium through the countercurrent multiplier mechanism.
The medulla oblongata descends as the?
diencephalons
What does the medulla of the kidney contain?
it contains specialized nephrons
Does the cortex contain nephrons?
No, the cortex does not contain nephrons. Nephrons are the functional units of the kidneys and are predominantly located in the renal cortex and renal medulla.
