Final answer:
The hepatic fissure is likely referring to liver anatomy which is primarily located in the right upper quadrant of the abdomen, separated into right and left lobes by the falciform ligament. The liver's right lobe may also feature a quadrate lobe and a caudate lobe.
Step-by-step explanation:
The hepatic fissure, which is not a commonly used term for any specific liver anatomy, is likely referring to the division between lobes of the liver or the area where the liver connects to other structures via ligaments. However, if the question is aiming to locate where the liver itself is primarily situated, it would be the right upper quadrant (RUQ) of the abdomen. This is due to the liver's position occupying a large volume of the RUQ, although it does extend across the midline to a small extent in the left upper quadrant. The liver is divided into the larger right and smaller left lobes, separated by the falciform ligament.
Additionally, within the right lobe of the liver, some anatomists identify an inferior quadrate lobe and a posterior caudate lobe. Furthermore, the liver's connection to the abdominal wall involves the falciform ligament, which is a remnant of the umbilical vein separating the liver into right and left lobes. The right colic flexure, also known as the hepatic flexure, is an anatomical landmark located inferior to the liver where the ascending colon takes a sharp turn to the left as it transitions into the transverse colon.
