An extension of a double layer of peritoneum between visceral organs is best described as what?

• A. Ligament
• B. Mesentery
• C. Capsule
• D. Fossa

Answer: (A)

A ligament. Peritoneal folds that connect two organs or connect an organ to the abdominal wall are ligaments. They are made of a double layer of peritoneum that links structures and often contains vessels. This differs from a mesentery, which specifically attaches an organ (typically a portion of the intestine) to the posterior abdominal wall and transmits vessels. A capsule is the organ’s outer covering, not a peritoneal fold, and a fossa is a recess or hollow. So the extension described fits the definition of a ligament.
