Unravel the mystery of Right Upper Quadrant (RUQ) Abdominal Pain The abdominal region of your body encases organs which are vital for the proper functioning of our body. These organs often work in a mutually symbiotic relationship inside your body. To understand the anatomy and function of these organs they are divided into 4 equal abdominal quadrants. This division helps clinicians to localize, identify, and diagnose if the patient is suffering from abdominal pain. The four-division are chartered out by a vertical line called (media plane) linea alba that splits the abdomen in vertical half and the transumbilical plane divides it into horizontal half. These two planes intersect each other at an umbilicus separating the four quadrants and giving them a distinct appearance.
