Quadrate Line
The Quadrate Line is a term used in anatomy to describe a line on the inferior surface of the liver. It is a significant anatomical landmark that helps in the identification of the gallbladder and the bile ducts.
Etymology[edit | edit source]
The term "quadrate" is derived from the Latin word "quadratus" which means "square". This is in reference to the roughly square shape of the area of the liver where this line is found.
Anatomy[edit | edit source]
The Quadrate Line is located on the inferior surface of the liver, between the gallbladder on the right and the round ligament on the left. It runs from the umbilical fissure to the gallbladder fossa, marking the lower border of the quadrate lobe of the liver.
Clinical Significance[edit | edit source]
The Quadrate Line is an important anatomical landmark in hepatobiliary surgery, as it helps in the identification of the gallbladder and the bile ducts. It is also used in the diagnosis of various liver diseases, as changes in the position or appearance of the Quadrate Line can indicate pathological conditions such as hepatomegaly or cirrhosis.
