Which quadrant contains the appendix?

• A. Left Upper Quadrant
• B. Right Upper Quadrant
• C. Right Lower Quadrant
• D. Left Lower Quadrant

Answer: (C)

Dividing the abdomen into four quadrants helps you map where organs are located. When you draw a vertical line down the middle and a horizontal line across at the level of the navel, you get the four quadrants. The appendix sits off the cecum in the lower right portion of the abdomen, so its usual position is in the right lower quadrant. That’s why this quadrant is the standard location associated with the appendix, especially for conditions like appendicitis. It’s good to know that in some people the appendix can be a bit higher, lower, or behind the cecum (retrocecal) or in the pelvis, but the common location remains the right lower quadrant.
