Peritoneal Folds and Fossce.—The ileo-ca.^cal artery, which is given off bythe superior mesenteric, divides into two terminal branches that straddle theterminal part of the ileum. The ant(4ior ])ranch is the smaller and passes downover the anterior aspect of the caecum, to a point a little below the level of theileo-csecal junction. The posterior branch usually divides into two, one ofw^hich passes into the inner and back part of the cnecum, while the other sup-. FiG. 256.—Retro-Ctecal (Subca?cal) Fossa.

As these vessels pass to their termination they are enclosed inperitoneal folds called thesuperior and inferior vascular folds. (Figs. 254 and 255.)Of these, the superior (ventral or anterior fold) is the smaller and appears merelyas a curved ridge, often containing masses of epiploic fat. The shallow fossaframed in its concavity is the superior ileo-caecal (or ileo-colic) fossa. (Fig. 254.)In six per cent of cases this fold is the larger of the two and forms the mesenteryof the appendix. (Fig. 256.) The inferior (dorsal or posterior) vascular fold isusually the larger and more important one of the two, forming the mesenteryof the appendix and conta
