Question

Which of the following statements are false?
(i) Outer cortex and inner medulla are the two zones in kidney.
(ii) Medulla is divided into few renal pyramids.
(iii) Pyramid projects into calyx.
(iv) Inward extension of cortex between the pyramids is called renal column of Bertini.

• A. (i) and (iv)
• B. (ii) and (iv)
• C. (ii) and (iii)
• D. None of these

Answer 1

The correct option is D None of these

The cortex and medulla make up two of the internal layers of a kidney and are composed of individual filtering units known as nephrons. Renal medulla is the inner-most region of the kidney, arranged into pyramid-like structures, that consists of the bulk of nephron structure. The renal column of Bertini is a medullary extension of the renal cortex in between the renal pyramids. The point of each pyramid, called the papilla, projects into a calyx.

So the correct option is 'None of these'.
