Which organ is located in the right lower quadrant?

• A. Liver
• B. Spleen
• C. Stomach
• D. Appendix

Answer: (D)

Understanding abdominal quadrants helps you map organs to regions. The abdomen is divided into four quadrants: right upper, left upper, right lower, and left lower. The liver sits mainly in the right upper quadrant, the spleen in the left upper quadrant, and the stomach in the left upper quadrant. The organ associated with the right lower quadrant is the appendix, a narrow tube attached to the cecum. While the appendix can vary in exact position (sometimes retrocecal or pelvic), it remains in the right lower quadrant overall. This localization matters clinically: appendicitis typically presents with pain that may start around the umbilicus and later localize to the right lower quadrant, with tenderness at specific points like McBurney’s. In physical therapy screening, recognizing RLQ abdominal pain or related signs helps differentiate musculoskeletal from visceral sources and flags potential urgent pathology.
