The 9 abdominal regions take a bit more time to name. I'm sure, however, that you can find the Umbilical region . . . around the umbilicus, of course! The areas above and below are given terms relative to the stomach (or at least where people think the stomach is: Epigastric (Epi = above, gastric = stomach), and Hypogastric (Hypo = below, gastric = stomach). The six remaining regions are divided into left and right , so there are only three more names to learn. The regions on either side are named according to the area of the spine (the lumbar region is the lower back): Left Lumbar and Right Lumbar. The regions on either side of the Hypogastric are named according to the bone that makes up the crest of the pelvis (The Iliac crest): Left Iliac and Right Iliac. Lastly, the two regions on either side of the Epigastric are named according to the organs' placement below the cartilage (chondro = cartilage) attaching the ribs to the sternum (costal cartilage, costal = ribs). Since these organs are under the cartilage, their names should make sense: Left Hypochondriac and Right Hypochondriac
