Life and Health 



form occurs in the ligaments which bind the vertebrae 

 together, in the true vocal cords, and in certain ligaments 

 of the larynx. 



27. Areolar or Cellular Tissue. This tissue, thus named 

 by the older anatomists, consists of bundles of delicate 

 fibers interlacing and crossing one another, forming irregular 



spaces or meshes. These little 

 spaces, in health, are filled with 

 fluid that has oozed out of the 

 blood vessels. The areolar tissue 

 forms a protective covering for 

 delicate and important organs. 

 X 28. Adipose or Fatty Tissue. 

 In almost every part of the body 

 there is found a variable quan- 

 tity of adipose or fatty tissue. 

 Examined by the microscope, 

 the fat cells are seen to be 

 minute sacs of exceedingly 

 delicate, structureless membrane 

 filled with oil. 



This tissue is usually plentiful 

 beneath the skin, in the abdom- 

 inal cavity, on the surface of the 

 heart, in the marrow of bones, and elsewhere. 



Experiment 3. To examine white fibrous tissue. Snip off a very 

 minute portion from a tendon of a rabbit, or any small animal 

 recently dead. Tease the specimen with needles, mount in salt solu- 

 tion, and examine under a high power. Note the course and characters 

 of the fibers. 



Experiment 4. To examine elastic tissue. Tease out a small 

 piece of ligament from a rabbit's leg in salt solution ; mount in the 

 same, and examine as before. Note the curled elastic fibers.
