SYNOVIAL SYSTEM. 



Q. In what respects does this system resemble the se- 

 rous? 



. In its form, the sac without opening; in its texture, 

 which is cellular ; and in its functions, those of exhalation 

 and absorption. 



Q. In what respects do they differ? 



*#. In the composition of their fluids. Dropsical affec- 

 tions of the cellular and serous tissues do not induce sy- 

 novial dropsies, and vice versa. The synovial tissues are 

 not so subject to tubercular diseases as the serous. Adhe- 

 sions do not take place in the synovial tissues as in the se- 

 rous. The synovial membranes are not locomotive as the 

 serous were said to be. The fluids of synovial and general 

 dropsy are not alike. 



Q. How is the synovial system divided ? 



*#. Into that of the joints, and that of the tendinous 

 grooves. 



1. Of the Articular Synovial System. 



Q. How are the fluids of the system separated from the 

 blood? 



%#. In three ways. By secretion from a gland, inter- 

 mediate to the blood-vessels, which bring the blood, and 

 the excretory which carries off the secreted fluid; by ex- 

 halation, where there is a direct continuity of blood-ves-
