OP THE CELLULAR SYSTEM. 55 



Q. What would be the consequence of a loose sub-mu- 

 cous cellular texture? 



*ft. Dropsy would form in a loose texture, and the hol- 

 low organs be closed by their sides being pressed into 

 contact. 



Q. What exempts the sub-mucous cellular texture from 

 emphysema? 



Jl. The density of its structure, which prevents gaseous 

 distention. 



Q. Why is the sub-cutaneous cellular tissue more liable 

 to phlegmon than the sub-mucous? 



#. Perhaps, because of its laxity of structure, and of 

 its freer exposure to the causes of phlegmonous inflamma- 

 tion. 



Q. There is yet another important result from the den- 

 sity of the structure of the sub-mucous cellular coat? 



/?. It fits it for giving origin and insertion to the mus- 

 cular fibres of the hollow organs, such as the stomach, 

 bowels, and bladder. 



Of the Sub-serous Cellular Texture. 



Q. Is this texture generally loose or dense? 



#. Remarkably loose; it is liable to serous and emphy- 

 sematous distention. 



Q. Why is it thus loose? 



*fl. For adaptation to the dilatations and contractions in 

 the serous membranes. 



Q. Can you give some examples of dense, adherent, 

 serous texture? 



#. The two layers of the pericardium the adhesion 

 of the arachnoides to the dura mater" are instances.
