Regions of the Abdomen and their Contents
Regions of the abdomen and their contents (edge of costal cartilages in dotted outline)."For convenience of description the abdomen may be artificially divided into nine regions by drawing two circular lines around the body parallel with the cartilages of the ninth ribs, and the highest point of the crests of the ilia; and two vertical lines from the cartilage of the eighth rib on each side to the center of Poupart's ligament. The vicar contained in these different regions are as follows: -- Right Hypochondriac - the right lobe of the liver and gall-bladder, hepatic flexure of the colon, and part of the right kidney. Right Lumbar - ascending colon, part of the right kidney, and some convolutions of the small intestines. Right Inguinal (Iliac) - the caecum, appendix caeci. Epigastric Region - the middle and pyloric end o the stomach, left lobe of the liver, the pancreas, the duodenum, part of the kidneys and the suprarenal capsules. Umbilical Region - the transverse colon, part of the great omentum and mesentery, transverse part of the duodenum, and some convolutions of the jejunum and ileum, and part of both kidneys. Hypogastric Region - convolutions of the small intestines, the bladder in children, and in adults if distended, and the uterus during pregnancy. Left Hypochondriac - the splenic end of the stomach, the spleen and extremity of the pancreas, the splenic flexure of the colon, and part of the left kidney. Left Lumbar - descending color, part of the omentum, part of the left kidney, and some convolutions of the small intestines. Left Inguinal (Iliac) - sigmoid flexure of the colon." — Kimber, 1907.
