In an embryo of 5 months (Fig. 302) the diaphragm has been completed in the way described in Chapter XIII. The oesophagus, not included in the preceding drawings, is seen passing through it. The thin lateral extensions of each coronary ligament {ligamenta triangularia) mark the position of the former appendages, and filling their dorsal concavity is the portion of the diaphragm which formed last, and which completes the separation of pleural and peritoneal cavities. The vena cava inferior now fills its plica, which has become broad. The lesser omentum is very thin except 10 They were probably included by Lieberkuhn (1876) among 1 the "villi" which occur where the omphalomesenteric veins enter the heart, and which were said to be so related to the developing liver that they contained the first blood vessels of that organ.
