Body Regions

For orientation, the abdomen can be divided by imaginary lines into nine regions, which are shown in Figure 5-4. The sections down the midline are the:

• epigastric (ep-i-GAS-trik) region, located above the stomach

• umbilical (um-BIL-i-kal) region, named for the umbilicus, or navel

• hypogastric (hi -po -GAS-trik) region, located below the stomach The lateral regions are the: _ _ _

• right and left hypochondriac (hi -po-KON-dre-ak) regions, named for their position near the ribs, specifically near the cartilages (root chondr/o) of the ribs,

• right and left lumbar (LUM-bar) regions, which are located near the small of the back (lumbar region of the spine) _

• right and left iliac (IL-e-ak) regions, named for the upper bone of the hip, the ilium. These regions are also called the inguinal (ING-gwi-nal) regions, with reference to the groin.

More simply, but less precisely, the abdomen can be divided by a single vertical line and a single horizontal line into four sections (Fig. 5-5), designated the right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ).

Additional terms for body regions are shown in Figures 5-6 and 5-7. You may need to refer to these illustrations as you work through the book.
