Quadrant (abdomen)

（重定向自RUQ）

Diagram showing which organs (or parts of organs) are in each quadrant of the abdomen

The human abdomen is divided into regions by anatomists and physicians for purposes of study, diagnosis, and therapy. In the four-region scheme, four quadrants allow localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved. The quadrants are referred to as the left lower quadrant, left upper quadrant, right upper quadrant and right lower quadrant, as follows below. These terms are not used in comparative anatomy, since most other animals do not stand erect.
