The apron-like structure attached to the greater curvature of the stomach is the:

1. Mesentery

2. Omentum

3. Ligamentum

4. Peritoneum

The correct answer is: Omentum

The apron-like structure attached to the greater curvature of the stomach is known as the omentum. Specifically, this refers to the greater omentum, which consists of a fold of peritoneum that hangs down from the stomach over the intestines. Its role includes protecting abdominal organs, containing fat, and permitting movement of the digestive organs, thereby contributing to immune responses and the management of infections within the abdominal cavity. Mesentery refers to the folds of peritoneum that attach the intestines to the posterior abdominal wall, providing support and containing blood vessels and nerves. Ligamentum generally refers to a connective tissue structure that connects bones or supports organs, which is not applicable in the context of the stomach’s anatomy. The peritoneum is a serous membrane lining the abdominal cavity and covering the abdominal organs but is not specific to the structure adjacent to the stomach. Thus, the identification of the omentum as the structure in question is accurate given its distinct characteristics and functions related to the digestive system.
