Hepatoduodenal ligament
Hepatoduodenal Ligament
Hepatoduodenal ligament (pronunciation: heh-pah-toh-doo-oh-deh-nal lig-uh-ment) is a significant structure in the anatomy of the digestive system.
Etymology
The term "hepatoduodenal" is derived from two Greek words: "hepar" meaning liver and "duodenum" meaning the first part of the small intestine. The term "ligament" is derived from the Latin word "ligamentum" which means to bind or tie.
Definition
The hepatoduodenal ligament is a double layer of peritoneum that extends from the liver to the duodenum. It contains the portal triad, which includes the hepatic artery, portal vein, and bile duct.
Function
The primary function of the hepatoduodenal ligament is to secure the liver to the abdominal wall and the diaphragm. It also serves as a conduit for the structures of the portal triad.
