THE CELLULAR TISSUE. 



of cells hence the name Cellular these cells are of varied 

 size and shape, and all communicate. 



The most beautiful specimen of 

 this tissue is seen in the anterior 

 mediastinum after throwing back 

 the sternum. Here 

 the cells are very dis- 

 tinct, though in other 

 places they are so 

 compact as to appear 

 membranous. The 

 extent of the cellular 

 tissue is commensurate with that of the entire body and its 

 various organs. It is found beneath the common integu- 

 ments, as extensive as the skin itself, forming a general 

 external layer, called the subcutaneous cellular tissue. It 

 likewise surrounds every organ, and every part and fibre 

 belonging to each organ. In a word, there is no part 

 where it is not to be seen; and it may very properly be 

 termed the matrix or soil in which germinate and expand 

 all the other structures. 



Bordeu, in consequence of its peculiar connections, styles 

 it a Cellular atmosphere. 



The/orm of this Tissue, as just stated, is Cellular, but in 

 addition to this special form, it has another and more varied 

 one, which it derives from its intimate relationship with 

 the whole body and its different parts, so that if this Tis- 

 sue could be separated entire from every part and organ, it 

 would present a perfect outline of the whole system. It 

 would then be seen to form a series of moulds or chambers, 

 each varying in size, and adapting itself to the organ to be 

 accommodated. 



Around the fasciculi of muscle, it takes the form of little 

 tubes, as numerous as the muscular fibres themselves con- 

 nected with hollow organs, it puts on the form of a mem-
