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.

The four types of cecum. Type I is the infantile form which persists throughout life, in about 2 percent of cases. In Type II the conical cecum had become quadrate by the growing out of a saccule on either side of the anterior longitudinal band. The saccules are of equal side, and the appendix arises from between them instead of from the apex of a cone. This type is found in 3 percent of cases. Type III is the normal type of man. Here the two saccules, which in the second type were uniform, have grown at unequal rates, the right with greater rapidity than the left. This type occurs in about 90 percent of cases. Type IV is merely an exaggerated condition of the third; the right saccule is still larger, and at the same time the left saccule had been atrophied, so that the original apex of the cecum, with the appendix, is close to the ileocecal junction, and the anterior band courses inward to the same situation. This type is present in about 4 percent of cases.

The iliac and pelvic colons, from a formalin-hardened male body, aged 30. The pelvic colon was usually long; its course is shown, as well as that of the beginning of the rectum, by dotted lines. It first ran across the upper surface of the bladder to the right pelvic wall, then recrossed the pelvis in a line posterior to is first crossing; finally it returned towards the middle line, and passed into the rectum. As a rule, after crossing to the right side of the pelvis, the pelvic colon turns backwards and inwards to reach the middle line, where it passes into the rectum.
