Which hepatic ligament helps define the diaphragmatic bare area by connecting to the diaphragm at its margins?

• A. Triangular ligament
• B. Coronary ligament
• C. Falciform ligament
• D. Hepatoduodenal ligament

Answer: (B)

The diaphragmatic bare area is the part of the liver directly contacting the diaphragm that is not covered by peritoneum, and its borders are defined by the peritoneal reflections of the coronary ligament as it attaches the liver to the diaphragm. These reflections extend to form the left and right triangular ligaments at the margins of the bare area, so the coronary ligament marks the boundary of this region. The other ligaments have different roles: the falciform ligament anchors the liver to the anterior abdominal wall and contains the ligamentum teres; the hepatoduodenal ligament links the liver to the duodenum as part of the lesser omentum; and the triangular ligaments are the edges of the coronary ligament at the diaphragmatic margins.
