Ligaments or Supports of the Liver

The liver is the largest solid organ and the largest gland in the human body. It is located below the diaphragm in the right upper quadrant of the abdominal cavity. The liver is a peritoneal organ positioned in the right upper quadrant of the abdomen. It is the largest visceral structure in the abdominal cavity and the largest gland in the human body.

Supports of the liver:

(A) Ligaments of the liver –

Peritoneal folds – are double layers of peritoneum that pass from one organ to another or from an organ to one of the abdominal walls. The peritoneum connects the liver in 4 locations: the coronary ligament, the left, and right triangular ligaments, and the falciform ligament. The left triangular ligament is a peritoneal suspensory ligament of the liver. It is formed by the fusion of the superior and inferior reflections of the coronary ligament.

(1) Falciform ligament – Extends from the Right Rectus muscle to the bare area of the Liver.

(2) Coronary ligament – Formed from Leaves Falciform ligament.

(3) Right triangular ligament – Right most Lateral portion is a continuation of Coronary Ligament.

(4) Left triangular ligament – Left Anterior section is Continuous w/ FALCIFORM LIGAMENT, a Posterior section is continuous with LESSER OMENTUM.

(5) Lesser omentum – It is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach.

True ligaments –

(1) Ligamentum teres hepatitis – Remnant of the Left Branch of Fetal Umbilical Vein.

(2) Ligamentum venosum – Separates the Left Lobe from the Caudate Lobe.

All these are the supports of the liver and help the liver to maintain its position.
