question 6 of 10

the parietal peritoneum would best be described as?

the serous membrane covering organs of the abdominopelvic cavity.
the serous membrane covering the inside of the abdominopelvic cavity.
the serous membrane covering the inside of the thoracic cavity.
the serous membrane covering organs of the thoracic cavity.

Explanation:

Identify the anatomical region

The term "peritoneum" refers specifically to the serous membrane associated with the abdominopelvic cavity, whereas "pleura" and "pericardium" are associated with the thoracic cavity.

Distinguish parietal versus visceral

In anatomical terminology, "parietal" refers to the outer layer that lines the walls of a body cavity, while "visceral" refers to the inner layer that directly covers the internal organs (viscera). Therefore, the parietal peritoneum lines the inside wall of the abdominopelvic cavity.

Answer:

• The serous membrane covering organs of the abdominopelvic cavity.
• The serous membrane covering the inside of the abdominopelvic cavity. (Correct answer)
• The serous membrane covering the inside of the thoracic cavity.
• The serous membrane covering organs of the thoracic cavity.
