serving delicate tissues like the master tissues from strain 

 and injury. It is said that if every other tissue were 



removed, the connective tis- 

 sue would still give a perfect 

 model of all the organs. The 

 tendons and ligaments consist 

 almost wholly of it. Leather, 

 the part of skins that is left 

 after tanning, is made up of 

 connective tissue. You have

 cate parts are destroyed and only connective tissue is left. 



57. Adipose (Fatty) Tissue. This soft tissue furnishes 

 cushions for delicate organs like the eye, forms a layer 

 under the skin, thus rounding 



out the form, and storing up 

 food for the use of nerve, mus- 

 cle, and other cells. The fat 6~ 

 is first deposited in the form of 

 minute globules in the connec- 

 tive tissue corpuscles, or cells ; 

 these globules gradually in- 

 crease in size. That fatty tissue 

 consists of both cells and fibers

the cells, and the cells are lodged in pockets formed by 



meshes of the fibers of connective tissue.
