INTRODUCTION 



White fibrous tissue is found in ligaments and tendons, 

 the tough lining membranes of bones, brain, etc. (Fig. 13, 

 A). It is composed mainly of bundles of strong, white 

 fibers containing nucleated cells.

A white fibrous tissue. 



B elastic or yellow fibrous tissue. 



Elastic or yelloiv fibrous tissue contains yellow, elastic 

 fibers (Fig. 13, B) bound into bundles by areolar tissue. 

 It appears in some ligaments, and in the walls of the 

 arteries, and in the air cells of the lungs. 



Adipose tissue is the fat of the body, and is found in 

 nearly all parts, usually in connection with areolar tissue. 

 Adipose tissue consists of protoplasmic cell walls filled 

 with liquid fat. 



18. Cartilage appears in two forms, hyaline cartilage 

 (Fig. 14) and fibrocartilage (Fig. 15), the first being clear 

 and free from fibers, the second composed largely of white 

 or yellow fibers. Cells are found in all kinds of cartilage, 

 but there is always a proportionately large amount of inter- 

 cellular matter which is produced by the cells.
