A piece of transverse colon from a child two years old. The three chief character- istics of the large intestine—sacculations, taenite, and appendices epiploicae—are shown. (Cunningham.) Further, the longitudinal muscle fibres of the large intestine do not form a con- tinuous layer around the gut, but are arranged in three longitudinal bands or taeniae {taeniae coli) (Fig. 104S). The large intestine, in its course, describes an arch which surrounds the convolutions of the small intestine. The segment of the intestinal tract where the small intestine joins the large is termed the ileocecal or ileocolic junction. The large intestine commences in the right inguinal region, in a dilated part, the cecum, together with a rudimentary structure, the appendix. It ascends through the right lumbar and right hypochondriac regions to the under surface of the liver; here it takes a bend to the left (hepatic flexure), and passes trans^'ersely across the abdomen on the confines of the epigastric and umbilical regions, to the left hypochondriac re- gion; it then bends again (splenic flexure), and descends through the left lumbar re- gion to the left iliac fossa, where it be- comes convoluted, and forms the sigmoid flexure; finally it enters the pelvis and descends along its posterior wall to the anus. The large intestine is divided into the cecum, colon, rectum, and anal Please note that these images are extracted from scanned page images that may have been digitally enhanced for rea
