CARTILAGES. 293 



The intervertebral cartilages are exceedingly elastic and 

 flexible, and permit the free movement of the spinal column 

 in almost any direction, and which is so necessary in the 

 execution of the various motions of the body. 



The articulations united by synchondrosis, as that of the 

 pubis, are remarkable for their strength, although at the same 

 time it admits a slight degree of extension and compression. 



Lastly, the epiglottis is enabled to preserve the erect posi- 

 tion so essential to the maintenance of life in consequence of 

 its exceeding elasticity.
