Which fibrous membrane surrounds the cortex of the kidney?

The renal capsule is a fibrous membrane that directly surrounds the cortex of the kidney. It is a thin, tough layer that provides protection and structural support to the kidney, helping to maintain its shape and integrity. The renal capsule also plays a role in protecting the kidney from infections and other external injuries. Its location and composition make it crucial for encapsulating the kidney, which is important for its overall function and health. Understanding the role of the renal capsule is essential in anatomy, especially in the context of renal protection and support structures.
