What are the two main types of nephron?
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.
What is the difference in role between cortical and juxtamedullary nephrons?
The main difference between cortical nephron and juxtamedullary nephron is that cortical nephron contains a short loop of Henle which only extends into the outer region of the renal medulla whereas juxtamedullary nephron contains a longer loop of Henle which extends deeper into the inner medulla.

What is a nephron and what are the two different classes of nephron?
What is a nephron, and what are the two different classes of nephron? structural/functional units of the kidney. composed of renal copuscle and renal tubule. nephrons carry out the process that forms urine.
What two types of nephrons exist are where are the found?
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.
What are juxtamedullary nephrons?
In other words, a juxtamedullary nephron is a nephron whose renal corpuscle is near the medulla, and whose proximal convoluted tubule and its associated loop of Henle occur deeper in the medulla than the other type of nephron, the cortical nephron.
How are cortical nephrons different from juxtamedullary nephrons Mcq?
How are cortical nephrons different from juxtamedullary nephrons? A. cortical nephrons lie almost entirely outside the renal medulla.
Which of the following are the types of nephrons?
By the location of renal corpuscles within the cortex, three types of nephron can be distinguished: superficial, midcortical, and juxtamedullary nephrons.
What type of tissue line the PCT?
simple cuboidal brush border epithelium
PCT is lined by a simple cuboidal brush border epithelium as its main function is absorption and microvilli present in the brush border cells greatly enhance the surface area for absorption. PCT absorbs all the essential nutrients, 100% glucose, 70%−80% electrolytes, and water.
What are Juxtamedullary nephrons?
Juxtamedullary nephrons have a glomerulus near the junction of the cortex and medulla and they have loops of Henle that penetrate deep into the medulla.
Which two types of cells are found in the Juxtaglomerular apparatus?
The juxtaglomerular apparatus consists of two types of cells:the macula densa, a part of the distal convoluted tubule of the same nephron. The juxtaglomerular apparatus consists of two types of cells:the macula densa, a part of the distal convoluted tubule of the same nephron.
What are the components of the nephrons?
The nephron is the functional unit of the kidney. Each nephron is composed of a renal corpuscle, the initial filtering component; and a renal tubule that processes and carries away the filtered fluid.
What is the anatomy and physiology of the nephron?
The Nephron – Anatomy & Physiology. The nephron of the kidney is made up of two major parts; the renal corpuscle and the tubules. These are then both sub-divided into various parts and overall it is this structure which allows the kidney to filter the blood and then alter the composition of this filtrate to ensure that waste products are excreted…
What is the important function of the nephrons?
The nephron is the basic functional and structural unit found in the kidneys. Its main functions include regulating the concentration of sodium salts and water by filtering the kidney’s blood, excreting any excess in the urine and reabsorbing the necessary amounts .
What are the parts of the nephron?
The major parts of the nephron are the renal corpuscle, the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. Each part has a significant, distinct function in urine production.
