The ligament that connects the posterior surface of the liver to the diaphragm is called which?

• A. Coronary
• B. Falciform
• C. Round
• D. Triangular

Answer: (A)

Peritoneal reflections tether the liver to surrounding structures, and the connection from the posterior liver surface to the diaphragm is via the coronary ligament. This ligament has right and left portions that run from the posterior liver to the diaphragmatic surface, forming the bare area where the liver abuts the diaphragm. At the sides, the coronary ligament gives rise to the triangular ligaments, which help anchor the liver laterally. The falciform ligament, by contrast, runs along the anterior surface to the abdominal wall and contains the ligamentum teres hepatis, while the round ligament is its remnant of the umbilical vein. Therefore, the ligament that connects the posterior surface of the liver to the diaphragm is the coronary ligament.
