FIBROUS SYSTEM. 



203 



Q. Why do you doubt the identity of muscular and 

 fibrous tissues? 



*#. Those tissues cannot be alike which vary so much 

 in chemical composition, in organization, in vital pro- 

 perties, and in functions. 



Q. What portions of the fibrous system are most liable 

 to inflammation? 



#. In those where there is most vascularity. 



Properties of the Fibrous System. 



Q. What physical properties belong to the fibrous sys- 

 tem? 



/?. Elasticity, and that quite obscure. 



Q. Are there any textural properties in this tissue? 



t#. Extensibility, which takes place slowly. In their 

 extension, the fibrous organs become sometimes thinner 

 than natural, in other cases they are thicker. Contractility 

 is also seen in these, and it is as slow in development as 

 the extensibility. 



Q. Give instances of the extension and contraction of 

 the fibrous system. 



.#. The dura mater in hydrocephalus; the fibrous or- 

 gans in the abdomen in pregnancy and ascites; now in the 

 restoration of these parts to their natural size, you see the 

 contractility of the fibrous organs. 



Q. What are the vital properties of this system? 



,#. Organic sensibility and insensible organic contrac- 

 tility; but animal contractility, and sensible organic con- 

 tractility do not belong to it. 



Q. What is the peculiarity of the animal sensibility in 

 this tissue?
