A quadrant refers to one of the four sections into which the abdomen is divided to help identify the location of symptoms, pain, or abnormalities. These are the right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ). Each quadrant contains specific organs—for example, the RUQ includes the liver and gallbladder, while the LLQ may involve the intestines or reproductive organs. This division is commonly used during physical examinations and diagnostic assessments to guide clinical evaluation.
