All of the following areas on anterolateral surface of left kidney are devoid of peritoneum, EXCEPT:
**Core Concept**
The anterolateral surface of the left kidney is an area where the peritoneum is absent, due to its proximity to the peritoneal cavity. However, there are specific regions on this surface where the peritoneum is present, and others where it is absent. Understanding the anatomy of the kidney and its relationship with the peritoneum is crucial for this question.
**Why the Correct Answer is Right**
The correct answer is related to the inferior aspect of the left kidney, where the peritoneum is present. This is due to the fact that the inferior surface of the kidney is in contact with the peritoneal cavity, specifically the sigmoid colon and the small intestine. The peritoneum covers this area to facilitate the movement of these abdominal organs.
**Why Each Wrong Option is Incorrect**
**Option A:** The anterior aspect of the left kidney is devoid of peritoneum, as it is in contact with the abdominal wall muscles and the diaphragm. The peritoneum does not cover this area.
**Option B:** The posterior aspect of the left kidney is also devoid of peritoneum, as it is in contact with the vertebral column and the psoas major muscle. The peritoneum does not cover this area.
**Option D:** The superior aspect of the left kidney is devoid of peritoneum, as it is in contact with the diaphragm and the pleura. The peritoneum does not cover this area.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the peritoneum is absent from the areas where the kidney comes into contact with the vertebral column, the psoas major muscle, the abdominal wall muscles, and the diaphragm.
**Correct Answer:** C.
