There is one arrangement in the abdomen which mustnot pass unnoticed. If the intestines were left to lie loose inthis cavity, they would constantly be subject to disolacementand injury. They are therefore fastened to the backbone byan arrangement, which secures them from any such accident,and at the same time allows of a sufficiently free motion of differ- digest roN. 57 The arrangement of the mesentery. Its ent parts of this tube. It is this. The intestinal tube makesthe margin of a broad sheet of membrane, the other edge ofwhich is gathered up and fastened to the spinal column. Thearrangement is like a ruffle with a puffed edging. The mem-branous sheet is called the mesentery. As the intestinal tube,the puffed edging, is much longer than the ruffle itself, themesentery, it is gathered on to the ruffle, as a seamstress wouldexpress it. Now, the mesentery is composed of two folds ofthe peritoneum, the smooth, shining, outer covering of the in-testines. The arrangement will be easily understood by thediagram in Fig. 16, which represents a section of the intestinewith the mesentery. The cav-ity of the intestine, o, is lined fig. the mucous membrane re-presented by the inner comes the muscular coat,and next the peritoneal, theouter, which, instead of makinga circular tube, as the other twocoats do, passes backward onboth sides of the intestine, tomake the mesentery, b.
