OP THE CELLULAR SYSTEM- 



Properties of the, Cellular Texture. 



1. Textural Properties. 



Q. What are the textural properties of this tissue? 



t#. Extensibility and contractility. 



Q. How is cellular extensibility evidenced ? 



JL. In fatty and serous cellular infiltrations, and in the 

 extension of this texture in moving the limbs. 



Q. Where is this extensibility most evident? 



#. In the cellular tissue, under the skin, and between 

 the muscles. It is slight in the sub-mucous texture. 



Q. Is this property suddenly or slowly manifested? 



t#. In some instances with great rapidity, as you see in 

 emphysema, and in cases of sudden tumefaction from 

 fractures, 



Q. What opposes the rupture of this texture? 



/?. Its extensibility, and a species of locomotion, by 

 which, if too violently drawn, it displaces the contiguous 

 cellular texture, draws it, and thus it is less extended. 



Q. Under what circumstances does it Iqse this extensi- 

 bility? *J . 



*ft. In several diseases, such as inflammation and can- 

 cer, &c. Y' 



Q. At what period is the contractility of texture great- 

 est in this tissue? 



J2. In youth: it loses it in advanced life. The wrin- 

 kles of old age are owing to the cellular texture not con- 

 tracting as in youth, so as to confine the skin close to the 

 subjacent organs.
