PEKITONEUM. 1235 Liver Epiploic foramen Stomacl Omental bursa Pancreas Duodenum, transverse part - Transverse colon apex of.the bladder below, where it usually becomes much stouter. Lateral to the urachus, and some distance from it (Fig. 965), will be found, in the same fatty tissue, (b) two stouter fibrous cords, the obliterated arteriEe umbilicales (O.T. ob- literated hypogastric arteries), forming the plica umbilicalis lateralis dextra and sinistra. Traced upwards, these also become more slender, and approach the urachus, along with which they are connected tO the Umbilicus. Below, Lesser omentum they grow thicker, and can be followed backwards along the side wall of the pelvis to the hypogastric arteries, which they join, (c) More laterally still, the inferior epigastric arteries are seen running up- wards and medially from the external iliac trunk on each side. When the anterior ab- dominal wall is examined from behind, it will be seen that these five structures, which lie on the front of the peritoneum, carry that mem- brane inwards towards the abdominal cavity in the form of five more or less distinct ridges, known as the plica umbilicalis media, plicae um- bilicales laterales, and plicae epigastricae, respectively. In fig. relation to these are found on each side three peritoneal fosste, known as the foveae in- guinales (O.T. inguinal pouches or fossae).

Mesentery of small intestine Small intestine Rectum Urinary bladder 964. DlAGEAMMATIC MEDIAN SECTION OF FEMALE BODY, to show the peritoneum on vertical tracing. The great sac of the peritoneum is blue and is represented as being much larger than in nature ; the bursa omentalis is coloured red; the peritoneum in section is shown as a white line : and a white arrow is passed through the epiploic foramen from the great sac into the bursa omentalis. The fovea lngumalis lateralis lies lateral to the inferior epigastric artery, and corresponds to the position of the abdominal inguinal ring. At its bottom is often found a dimple-like depres- sion of the peritoneum, indicating the point from which the processus vaginalis passed down, m connexion with the descent of the testicle. The fovea inguinalis medialis is situated between the inferior epigastric and the obliterated umbilical arteries ; whilst the fovea supravesicalis lies to the medial side of the obliterated umbilical artery, namely, between it and the urachus. Between the inferior epigastric artery laterally, the margin of the rectus abdominis muscle, and the inguinal ligament below is a small triangular region, called Hesselbach's triangle. The obliterated umbilical artery, in passing upwards, crosses this triangle, dividing it into a lateral and a medial part. The middle inguinal fossa corresponds to the lateral division of the triangle, and the medial fossa to its medial division. Still another fossa of the peritoneum is seen in this region, just beneath the medial part of the inguinal ligament, corresponding to the position of the femoral ring, and consequents known as the fovea femoralis. It may be added that the ductus deferens crosses the lateral part of the fovea femorahs, and the obliterated umbilical artery its medial part. The significance of those fossae is referred to in connexion with the applied anatomy of the inguinal and femoral regions. Near the median plane, above the umbilicus, the peritoneum is carried back from the anterior abdominal wall and diaphragm to the parietal surface of the liver in the form of a crescentic fold, the falciform ligament of the liver (described with the liver), which connects the liver to the abdominal wall. This fold lies somewhat to the right of the median plane, and extends almost as low down as the umbilicus. 79 a
