| The great omentum is not yet adherent to the transverse colon and mesocolon except for a short distance on the extreme right. |
| Tracing the omentum dorsad beyond the transverse colon and mesocolon the pancreas is reached. |
| This fossa opens caudad and extends cephalad to the root of the transverse mesocolon. |
| The adhesion, which in the human subject fuses this layer with the transverse colon and mesocolon, does not occur in the monkey. |
| In the typical arrangement of the parts the sigmoid or omega loop of the large intestine has a free mesocolon. |
| Fig. 549 shows the arrangement in unimpeded ccal descent without adhesion of colon and mesocolon to the parietal peritoneum. |
