The word "omentum minus" is a medical term used to describe the lesser omentum, a double layer of peritoneum that extends from the liver to the stomach. The correct phonetic transcription of the word is /o'mentum 'maɪnəs/. The first part of the word, "omentum," is pronounced as /o'mentum/, with the stress on the first syllable. The second part, "minus," is pronounced as /'maɪnəs/, with the stress on the second syllable. The spelling of this word accurately represents its pronunciation, making it easier for medical professionals to communicate and understand one another.
Omentum minus is a term used in anatomy to refer to a specific portion of the omentum, a fold of peritoneum, which is the membrane lining the abdominal cavity. It is an extension of the greater omentum located below the stomach and adjacent to the transverse colon.
The omentum minus, also known as the lesser omentum, is a double-layered sheet of peritoneum that connects the lesser curvature of the stomach and the beginning of the duodenum (the first part of the small intestine) to the liver. It consists of two distinct parts: the hepatogastric ligament and the hepatoduodenal ligament.
The hepatogastric ligament runs from the lesser curvature of the stomach to the visceral surface of the liver, helping to anchor and support these structures. It contains blood vessels, lymphatics, and nerves. The hepatoduodenal ligament connects the duodenum to the liver, forming a passage for the hepatic artery, the portal vein, and the common bile duct. It also contains lymph nodes and nerves.
The omentum minus plays a crucial role in the overall function of the digestive system. It helps to maintain the position and mobility of the stomach and the liver, while also providing a route for blood vessels and other structures to travel between them. Additionally, it provides a site for immune and inflammatory responses as it contains lymph nodes involved in immune surveillance and defense.
Lesser or gastrohepatic o., a peritoneal fold passing from the margins of the porta hepatis and the bottom of the fossa ductus venosi to the lesser curvature of the stomach and to the upper border of the duodenum for a distance of about an inch from the pylorus.

The word "omentum" derives from the Latin term "omentum" meaning "a covering" or "fat". In Latin, "minus" means "less" or "small". Therefore, "omentum minus" can be translated as "a smaller or lesser omentum". In the context of human anatomy, omentum minus refers to the lesser omentum, which is a double layer of peritoneum (a membrane lining the abdominal cavity) that connects the liver to the lesser curvature of the stomach.
