OP THE CELLULAR SYSTEM. 61 



Ji. In the interval formed by the fold of the mediastf- 

 num, about the pericardium, and where the large vessels 

 come out. 



Q. How does this pectoral texture communicate with 

 the abdominal ? 



fl. Through the diaphragmatic openings. 



Q. Where do you meet with external pectoral texture? 



*ft. In great quantities in the breasts of women and men, 

 and under the pectoral muscles. 



Q. Why has disease of the peritoneum more influence 

 on the right pleura than the left? 



*ft. The peritoneum on the right side being kept fixed by 

 the convex surface of the liver, the communications of 

 the abdominal and pectoral cellular textures are there 

 more constant and operative, than where the peritoneum, 

 towards the left pleura, is loose and floating with the 

 viscera. 



Q. With what has the pectoral cellular texture peculiar 

 relation ? 



<fl. With the cellular texture of the superior extremities. 



Q. Where is the abdominal cellular texture most abun- 

 dant? 



Ji. Where the large vessels enter the viscera, and about 

 the kidneys. 



Q. What are the principal relations and communica- 

 tions of the abdominal cellular texture? 



#. They are with the genital organs and inferior extre- 

 mities through the abdominal ring and crural arch. The 

 abdominal cellular texture bears the relation to that of the 

 lower extremities, which the pectoral does to that of the 

 superior. 



Q. Is the cellular texture abundant in the pelvis?
