means of the unequal pressure which they produce in these 

 reservoirs, liquids having always a tendency to move towards 

 the point of least pressure. (See movements of the stomach, 

 of the intestine, the bladder, uterus, etc.) 



In the latter case the muscular fibre is inserted in the 

 organs which it is intended to affect, in the levers which it 

 is to move (bones) by the medium of resisting cords (ten- 

 dons). The study of the ligaments belongs to that of the 

 bones (and of their articulations) ; the study of the aponeu- 

 roses, to that of the tendons and the muscles. The bones,

the articular cartilages, the ligaments, the tendons, the 

 aponeuroses, thus constitute the passive organs of loco- 

 motion. The tissues of these organs are so associated in 

 histological and chemical peculiarities, that they have been 

 classed together, and form a vast family, called group of 

 connective or collagenous tissue. The tendons, the aponeu- 

 roses, the ligaments, and the connective substance of the 

 organs form the connective or cellular tissue, properly so 

 called. 



Connective Tissue, properly so-called. This tissue has
