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 The Cecum. The cecum {iniesiinum cecum) (Figs. 1050 and 1051-1054), the commencement of the large intestine, is the large blind pouch situated below the ileocecal valve. Its blind end or fundus is directed downward, and its open end upward, communi- cating directly with the colon, of which this blind pouch appears to be the beginning or head, and hence the old name caput cecum coli was applied to it. Its size is variously estimated by different authors, but on an average it may be said to be
