Question:

Which of the following is correct about juxtamedullary nephrons?

Options:

1. They lack vasa recta
2. They are about 85% of the nephrons
3. Their glomeruli are in the outer cortex
4. They have long loops of Henle and are placed deep into the medulla

Solution:

Juxtamedullary nephrons are a type of nephrons present in the mammalian kidney. They are located in the cortex-medulla junction and have long loops of Henle that extend deep into the medulla. These nephrons play an important role in producing concentrated urine. The glomeruli of juxtamedullary nephrons are located close to the medulla, and they have a specialized blood supply known as the vasa recta, which helps in maintaining the concentration gradient in the medulla. Juxtamedullary nephrons constitute about 15% of the total nephrons in the kidney.
