Fig. 1. A 5 mm embryo simplified from models

Showing belly cavity through window in wall. Course of vitelline duct indicated by dotted lines on further side of cut; body stalk. Shows gut lying practically in median sagittal plane.

An example of the intestine placed in the median sagittal plane may be taken from the embryo shown in fig. 1. The embryo is one of 5 mm. in which a window has been cut in the left abdominal wall to expose the intestinal tube: this, disposed in what is practically the middle line of the cavity, forms a nearly right—angled V, the apex of which is continuous with the vitelline duct. The vitelline vein lies in the cavity in front of the proximal limb of the V, running up to join the sub-hepatic anastomosis above, and down to reach the vitelline duct externally. It is worth noting that the hinder limb of the V is continuously curved, corresponding with the umbilical arteries, on and between which it lies.
