Traditional descriptive anatomy of the liver is based on surface features such as lobulations, impressions and ligaments (see also hepatic anatomy). In the frontal view, the round ligament, the remnant of the umbilical vein (see hepatobiliary embryology), runs into the umbilical fissure and is enfolded by the falciform ligament, the remnant of the ventral mesentery. The falciform splits into the coronary ligaments encircling the dome of the liver.
The posterior view of the liver shows the central transverse hilum and impressions of adjacent organs. Note that the hepatic veins are in the central (bare) area surrounded by the coronary ligaments. Overzealous division of the left triangular ligament can injure the left hepatic vein.
