Which of the following statements is incorrect regarding the structure of a mammalian nephron?
Options
- AThe Malpighian corpuscle, proximal convoluted tubule and distal convoluted tubule are situated in the cortical
- BThe efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule.
- CIn the majority of nephrons, the loop of Henle is very long and runs deep into the renal medulla.
- DA minute vessel of the peritubular capillary network runs parallel to the Henle's loop forming a 'U' shaped va
Correct answer
C. In the majority of nephrons, the loop of Henle is very long and runs deep into the renal medulla.
Step-by-step solution
In the mammalian kidney, there are two types of nephrons: cortical nephrons and juxtamedullary nephrons. In the majority of nephrons (about 85 % ), the loop of Henle is too short and extends only very little into the medulla. These are called cortical nephrons. In some of the nephrons (about 15 % ), the loop of Henle is very long and runs deep into the medulla. These are called juxtamedullary nephrons. Therefore, the statement that in the majority of nephrons the loop of Henle is very long and runs deep into the re
