Medical Assistant Prep / Unit 2 MAS 035 short lesson, about 20 seconds
Four Quadrants of the Abdomen
Captions available
The idea
The abdomen is roughly divided into four quadrants: right upper, right lower, left upper and left lower.
In practice
The stomach sits in the left upper quadrant; tenderness in the right lower quadrant names one specific region, often shortened to its initials.
Where people slip
Right and left are the patient's, not yours.
