GENERAL TOPOGRAPHY OF ABDOMEN

1. To facilitate clinical description, the abdomen is divided into 4 quadrants or 9 regions by lines on the surface of the anterior abdominal wall.
2. 4 quadrants are created by vertical and horizontal lines passing through the umbilicus.
3. The 9 regions are delineated by 2 vertical and 2 horizontal lines.

9 REGIONS
4. 2 vertical lines are the midclavicular lines which extend to the midinguinal point.
5. Lower transverse line - intertubercular plane,  line drawn between the tubercles of the iliac crest.
6. Upper transverse line - transpyloric plane which lies midway between the suprasternal notch and superior surface of the symphysis pubis (or b/w the xiphisternum + umbilicus).
7. Using the 4 lines, the 3 central regions from above down are - epigastrium, umbilical, suprapubic.
8. Similarly, the lateral regions from above down are - hypochondrial, lumbar, iliac.
