Human anatomy, including structure and development and practical considerations . Pouparts ligament. A slight fold,caused by the vas deferens or the round ligament, is described as running downwardfrom the ring into the pelvis ; the fact is, however, that the structure can be onlyindistinctly seen through the peritoneum, and a raised fold is rare. It forms theouter border of the slightly markedyrw^ra/ depression (fovea femoralisj opposite thefemoral ring (annulus cruralis), between the pubes and Pouparts ligament. Theperitoneum is continued laterally on either side without presenting any feature thatcalls for description until it reaches the ascending or the descending colon. Allthe serous covering anterior to these structures is derived from the parietal perito-neum ; that posterior to them is derived from the mesenteries of the colons which Fig. 1.

It will be considered parietal peritoneum is also to be traced onto the under surface of the dia-phragm until far back it meets the folds derived from the mesenteries. On eitherside of the bundle of fibres arising from the ensiform cartilage there is an inter-ruption in the muscle of the diaphragm, where only areolar tissue separates theperitoneum and the pleura or pericardium. The parietal peritoneum is continued into the pelvis, where it meets the mesen-tery of the colon and is continued over the bladder, and in the female over theuterus and Fallopian tubes.
