The coronary ligament of the liver
Liver
The liver is a vital organ present in vertebrates and some other animals. It has a wide range of functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion...

 refers to parts of the peritoneal reflections that hold the liver to the inferior surface of the diaphragm
Thoracic diaphragm
In the anatomy of mammals, the thoracic diaphragm, or simply the diaphragm , is a sheet of internal skeletal muscle that extends across the bottom of the rib cage. The diaphragm separates the thoracic cavity from the abdominal cavity and performs an important function in respiration...

Structure

The convex diaphragmatic surface of the liver (anterior, superior and a little posterior) is connected to the concavity of the inferior surface of the diaphragm

In the anatomy of mammals, the thoracic diaphragm, or simply the diaphragm , is a sheet of internal skeletal muscle that extends across the bottom of the rib cage. The diaphragm separates the thoracic cavity from the abdominal cavity and performs an important function in respiration...

 by reflections of peritoneum
Peritoneum
The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom — it covers most of the intra-abdominal organs — in amniotes and some invertebrates...

. The coronary ligament is the largest of these, having an anterior (frontal) and posterior (back) layers.

The diaphragmatic surface of the liver that is in direct contact with the diaphragm (just beyond the peritoneal reflections) has no peritoneal covering, and is termed the bare area of the liver
Bare area of the liver
The coronary ligaments represent reflections of the visceral peritoneum covering the liver onto the diaphragm. As such, between the two layers of the coronary ligament there is a large triangular surface of the liver devoid of peritoneal covering; this is named the bare area of the liver, and is...

.

The anterior layer of the coronary ligament is formed by the reflection of the peritoneum from the upper margin of the bare area of the liver to the under surface of the diaphragm.

The posterior layer of the coronary ligament is reflected from the lower margin of the bare area and is continuous with the right layer of the lesser omentum
Lesser omentum
The lesser omentum is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum.- Structure :...

.

The anterior and posterior layers converge on the right and left sides of the liver to form the right triangular ligament
Right triangular ligament
The right triangular ligament is situated at the right extremity of the bare area, and is a small fold which passes to the diaphragm, being formed by the apposition of the upper and lower layers of the coronary ligament....

 and the left triangular ligament
Left triangular ligament
The left triangular ligament is a fold of some considerable size, which connects the posterior part of the upper surface of the left lobe of the liver to the diaphragm; its anterior layer is continuous with the left layer of the falciform ligament....

, respectively. In between the two sides of the anterior layer, the reflection of peritoneum has an inferior continuation termed the falciform ligament
Falciform ligament
The falciform ligament is a ligament that attaches the liver to the anterior body wall.It is a broad and thin antero-posterior peritoneal fold, falciform in shape, its base being directed downward and backward and its apex upward and backward...

. The falciform ligament contains the round ligament of liver
Round ligament of liver
In anatomy, the round ligament of liver is a degenerative string of tissue that exists in the free edge of the falciform ligament of the liver...
