Question 791: Cantlie's line is associated with which organ?

• A. Liver (Correct Answer)
• B. Kidney
• C. Stomach
• D. Heart

Explanation: ***Liver*** - **Cantlie's line** is an imaginary line that runs from the gallbladder fossa to the inferior vena cava, dividing the **liver** into its functional right and left lobes [1]. - This anatomical landmark is crucial in **hepatic surgery** for planning resections and understanding segmental anatomy [1]. *Heart* - The heart's anatomy is described using landmarks like the sternum, ribs, and vertebral levels, but **Cantlie's line** is not relevant to its internal or external divisions. - Cardiac surgeons divide the heart into chambers and great vessels, not using a functional line like Cantlie's. *Kidney* - The kidney's anatomy is divided into a cortex and medulla, and externally into poles and borders, with no associated line called **Cantlie's line**. - Renal surgery relies on landmarks such as the renal hilum and vascular supply. *Stomach* - The stomach is divided into regions like the fundus, body, and pylorus, and its surgical anatomy is based on its curvatures and blood supply. - **Cantlie's line** has no anatomical or surgical relevance to the stomach.
