Four Quadrants of the Abdominal Cavity
For more general clinical descriptions, the abdominal cavity is divided into four quadrants by a horizontal transumbilical plane passing through the umbilicus and a vertical median plane intersecting the horizontal plane at the umbilicus. The four quadrants thus formed are: Right upper quadrant. Left upper quadrant. Right lower quadrant. Left lower quadrant.
