Whatis the different between crtical and justamedibulary neprons
Answers
Answer:
Cortical Nephron: Cortical nephron is a microscopic structural and functional unit of the kidney with a short loop of Henle.
Juxtamedullary Nephron: Juxtamedullary nephron is a microscopic structural and functional unit of the kidney with a long loop of Henle.
Loop of Henle
Cortical Nephron: Cortical nephrons have a short loop of Henle, which penetrates only the outer renal medulla.
Juxtamedullary Nephron: Juxtamedullary nephrons have a long loop of Henle extending deep into the renal medulla.
Malpighian corpuscles
Cortical Nephron: The Malpighian corpuscles of the cortical nephrons are located in the outer part of the renal cortex.
Juxtamedullary Nephron: The Malpighian corpuscles of the juxtamedullary nephrons are situated close to the renal medulla.
Occurrence
Cortical Nephron: Cortical nephrons occur in all vertebrates.
Juxtamedullary Nephron: Juxtamedullary nephrons occur only in birds and mammals.
Function
Cortical Nephron: The major part of the regulatory and excretory functions of the human body is carried out by the cortical nephrons.
Juxtamedullary Nephron: The juxtamedullary nephrons concentrate or dilute urine.
Glomerulus
Cortical Nephron: At the beginning of each cortical nephron, in the outer renal cortex, is located a small glomerulus.
Juxtamedullary Nephron: At the beginning of each juxtamedullary nephron is located a large glomerulus.
Vasa recta
Cortical Nephron: As a result of the short loop of Henle, the vasa recta of the cortical nephrons is also small.
Juxtamedullary Nephron: The long loop of Henle of the juxtamedullary nephrons is surrounded by a large vasa recta network.
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.
