Renal columns separate the renal (medullary) pyramids.
Solución
The extensions of cortex-like tissue that separate the renal (medullary) pyramids are called renal columns.
Here’s a brief explanation of the options:
- Renal pelvis: This is the funnel-shaped structure that collects urine from the renal pyramids and channels it into the ureter.
- Renal capsule: This is a fibrous outer covering of the kidney that provides protection.
- Renal hilum: This is the entry and exit point for blood vessels, nerves, and the ureter, but it does not separate the pyramids.
- Renal columns: These are the extensions of the renal cortex that dip down between the renal pyramids, providing structural support and separating them.
Thus, the correct answer is renal columns.

Extra Insights
The renal columns are the extensions of cortex-like tissue that separate the renal (medullary) pyramids. These columns are composed of cortical tissue that extends between the pyramids, helping to support the structure of the kidney and providing a pathway for blood vessels and urine-producing elements.
In terms of function, the renal columns play a crucial role in maintaining the kidney’s organization and ensuring the proper flow of urine from the renal pyramids into the calyces, and then into the renal pelvis. This efficient design is essential for the kidney’s filtration and excretion processes, making columns an interesting part of kidney anatomy!
