Detailed explanation-2: -The extensions of the renal cortex into the renal medulla, between the pyramids, are termed renal columns (columns of Bertini).
Detailed explanation-3: -The medulla is divided into 8-18 conical regions, called the renal pyramids; the base of each pyramid starts at the corticomedullary border, and the apex ends in the renal papilla which merges to form the renal pelvis and then on to form the ureter.
Detailed explanation-4: -The ventral portion of the medulla oblongata contains the medullary pyramids. These two ridge-like structures travel along the length of the medulla oblongata and are bordered medially by the anterior median fissure.
