Greater Omentum - English Definition & Meaning

Definition

The greater omentum is a large apron-like fold of visceral peritoneum that hangs down from the stomach. Think of it as the body's internal "bodyguard," rich with fat and immune cells. It drapes over the intestines, protecting and insulating them. It also helps to localize infections, preventing them from spreading widely. It is very pliable and mobile and migrates towards areas of inflammation or injury, walling them off. The omentum can be compared to a "surgical policeman" of the abdomen due to its ability to adhere to inflamed organs.

Etymology

The term "omentum" comes from the Latin word for apron or covering. "Greater" refers to its size and extent compared to the lesser omentum. The Latin word possibly comes from ob- + mentum (meaning "chin", "cover for the chin"). The term suggests a protective layer or shield. It reflects the structure's function in enveloping and safeguarding abdominal organs. The greater omentum is a fitting description for this expansive, protective fold.
