The liver is primarily divided by the falciform ligament.
Liver Division Explained
The liver, a vital organ, is not a single, uniform mass. Instead, it is separated into distinct lobes by anatomical structures.
Falciform Ligament
- The primary external division of the liver is achieved by the falciform ligament.
- This ligament acts as a kind of anatomical landmark on the anterior surface of the liver.
- It separates the liver into two main lobes:
- A larger right lobe.
- A smaller left lobe.
- The falciform ligament also serves to attach the liver to the anterior abdominal wall.
- At the base of the falciform ligament is the ligamentum teres, a remnant of the umbilical vein.
