The coronary ligament is a peritoneal reflection that suspends the liver from the diaphragm, specifically surrounding the liver’s bare area on its diaphragmatic surface. It consists of anterior and posterior parts around the bare area and, where these reflections meet at the edges, they form the right and left triangular ligaments anchoring the liver to the diaphragm. This distinguishes it from the falciform ligament, which is a separate peritoneal fold connecting the liver to the anterior abdominal wall (and contains the round ligament within its free edge). It is not the hepatic arteries (vessels) or the lesser omentum (which connects the stomach/duodenum to the liver).
