the abdominal cavity as the parietal peritoneum (peritonaeum 

 parietale) and covers the viscera as the visceral peritoneum 

 (peritonaeum viscerale). The space between these two layers, 

 which exists only upon dissection, is the peritoneal cavity 

 (cavum peritonaei). In the male this is completely closed, but 

 in the female it communicates with the exterior through the 

 abdominal openings of the Fallopian tubes. 



Great Omentum (Omentum majus). (Figs. 245, 258.) 



What is its position and form and of what tissue is it com- 

 posed ? 



What is its relation to that part of the large intestine passing 

 transversely across the abdomen (colon transversum) 1 Is its 

 relation in the adult the same as in the embryo? How is it re-

Transverse section passing through the bursa omentalis at the level of the foramen epiploicum, that 

 is, in-low the hepatocaval meso. Surface below the plane of section. Schematic. Thearro\v indicates 

 the opening between the V. cava inferior behind and the V. portae, ductus choledochus, and A. hepatica 

 propria in front. The great extent of the bursa omentalis is due to its lodging, at this level, the pro- 

 jecting lobus caudatus [Spigelii]. (From Fredet in Poirier et Charpy, Traite d'Anat. hum., Paris, 1900, 

 2 ed., t. iv. p. 1011, Fig. 576.)

 Does it enclose any cavity! 



Trace the anterior two layers to the lower margin of the 

 stomach. These two layers separate to enclose the stomach,
