What type of membrane covers the abdominal organs?

  1. Parietal membrane

  2. Fibrous membrane

  3. Visceral membrane

  4. Serous membrane

The correct answer is: Visceral membrane

The visceral membrane is the correct choice because it specifically refers to the inner layer of serous membranes that directly covers and adheres to the surface of the abdominal organs. This type of membrane serves several important functions, including providing a slippery, lubricated surface that allows for smooth movement of the organs against one another, which is particularly vital in spaces like the abdominal cavity where organs can expand and contract. The parietal membrane, while related, lines the cavity itself and does not directly contact the organs. A fibrous membrane generally refers to a connective tissue structure rather than a serous layer associated with internal organs. The serous membrane as a whole encompasses both the parietal and visceral layers; however, when specifically discussing the covering of the organs, the term visceral is the most appropriate.
