The protective covering of tissue surrounding each kidney is called what?

The protective covering of tissue surrounding each kidney is called what?

• A. Gerota's fascia
• B. Fascia
• C. Renal capsule
• D. Perirenal fat

Answer: (A)

The kidneys are enclosed by several layers, with the outer fibrous envelope surrounding the perirenal space being the protective covering. This sheath is the renal fascia, specifically called Gerota's fascia. It forms a distinct boundary around the kidney and its perirenal fat, helping contain infections or masses within that space and separating it from surrounding tissues. The other options describe either the innermost covering (renal capsule) or the fat layer inside the fascia (perirenal fat), or are too general (fascia) without naming the kidney’s specific envelope.
