NEET PG DENTAL EXAM

Detailed explanation-1: -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-2: -The parenchyma of the kidney is divided into two major structures: the external renal cortex and the deep part is the renal medulla. Grossly, these structures take the shape of 8–18 cone-shaped renal lobes, each containing renal cortex surrounding a portion of medulla (termed pyramids of Malpighi).

Detailed explanation-3: -The medulla consists of multiple pyramidal tissue masses, called the renal pyramids. In between the pyramids are spaces called renal columns through which the blood vessels pass. The tips of the pyramids, called renal papillae, point toward the renal pelvis. There are, on average, eight renal pyramids in each kidney.

Detailed explanation-4: -The renal medulla contains the renal pyramids, where urine formation takes place. Urine passes from the renal pyramids into the renal pelvis. This funnel-shaped structure occupies the central cavity of each kidney and then narrows as it extends out to join the ureter.
