Question

1. figure 15–2 is a longitudinal section of a kidney. (a) using the correct anatomical terminology, label the following regions/ structures indicated by leader lines on the figure and after each description. - fibrous membrane immediately surrounding the kidney. structure/region: ____. - basin - like area of the kidney that is continuous with the ureter. structure/region: __. - cuplike extension of the pelvis that drains the apex of a pyramid. structure/region: __. - area of cortex - like tissue running through the medulla. structure/region: __. - area of the kidney that contains the greatest proportion of nephron structures. structure/region: __. - striped - appearing structures formed primarily of collecting ducts. structure/region: ____.

Explanation:

Each answer corresponds to the standard anatomical term for the described kidney structure/region, based on urinary system anatomy.

1. The fibrous membrane directly surrounding the kidney is the renal capsule.
2. The basin-like structure continuous with the ureter is the renal pelvis.
3. The cuplike extension draining a renal pyramid apex is a minor calyx.
4. Cortex-like tissue extending through the medulla is the renal column (of Bertin).
5. The kidney region with the majority of nephrons is the renal cortex.
6. Striped structures made of collecting ducts are the renal pyramids (medullary pyramids).

Answer:

• Fibrous membrane immediately surrounding the kidney. Structure/Region: Renal capsule
• Basin-like area of the kidney that is continuous with the ureter. Structure/Region: Renal pelvis
• Cuplike extension of the pelvis that drains the apex of a pyramid. Structure/Region: Minor calyx
• Area of cortex-like tissue running through the medulla. Structure/Region: Renal column (of Bertin)
• Area of the kidney that contains the greatest proportion of nephron structures. Structure/Region: Renal cortex
• Striped-appearing structures formed primarily of collecting ducts. Structure/Region: Renal pyramid (medullary pyramid)
