text: organs of the 9 regions of the abdomen?   the nine regions are the left and right hypochondriac, the epigastric, the left and right lumbar, the umbilical, the left and right iliac (or inguinal), and the hypogastric (or pubic).  these are arranged like a tic-tac-toe grid.  altogether these nine regions contain all of the abdominopelvic organs found between the diaphragm and the pelvic floor.  so the list would include the liver, gall bladder, stomach, pancreas, spleen, small intestine, large intestine, rectum, appendix, kidneys, adrenal glands, ureters, urinary bladder, and the uterus, fallopian tubes, and ovaries in females.  this schema is used primarily by anatomists, seldom by clinicians, who tend to use the four-quandrant schema instead.  an common exception here, though, would be clinical references to pain in the upper abdominal area which is frequently referred to as epigastric in clinical notes.  most of the time such pain originates in the stomach, but severe epigastric pain is sometimes a symptom of myocardial infarction.  evaluation of other clinical data is needed to distinguish one from the other.
