54 OF THE CELLULAR SYSTEM. 



Q. -Where is this sub-cutaneous texture most dense? 



*#. On the scalp; on the palmar and plantar surfaces, 

 and at the annular ligaments. 



Q. Why is this texture loose, as in the face and on the 

 abdomen, and dense elsewhere? 



#. To favour the functions of parts, where looseness 

 avails some, and density others. 



Q. How does the density of cellular structure affect 

 dropsical and emphysematous swellings? 



*#. Where it is dense, there is neither a collection of 

 water nor air. 



Q. When is this density of cellular structure at the an- 

 nular ligaments most observable? 



*#. In infants, and in very fat persons. 



Q. What are the uses of the sub-cutaneous cellular tex- 

 ture? 



.#. It allows mobility to the skin, facility to the mo- 

 tions of subjacent parts, and it serves to defend from cold. 

 It is more abundant in winter than in summer, and it is 

 found in greater quantity in animals inhabiting cold cli- 

 mates. Recollect the chilliness which accompanies atte- 

 nuation in chronic diseases. 



Q. In what part of the cellular texture does serum most 

 readily accumulate? 



*ft. In the sub-cutaneous portion, and in this, because of 

 its laxity. 



Of the Sub-mucous Cellular Texture. 



Q. What is the great difference between the sub-mucous 

 and the sub-cutaneous cellular textures? 



Jl. The sub-mucous is much more dense in its whole 

 expansion.
