 surfaces, as costal cartilage and in the nose, larynx, trachea, and

bronchi. All bones except those of the vault of the skull and the 

 majority of the bones of the face are preformed in hyaline cartilage. 



In white fibrocartilage (Fig. 78) there are from the beginning, 

 even in precartilage, fibrous strands in the ground-substance. They 

 preponderate over the matrix and, as a rule, have a parallel direc- 

 tion. White fibrocartilage is found in the intervertebral and inter- 

 articular disks, the symphysis pubis, and in the insertion of the 

 ligamentum teres ; it deepens the cavity of ball-and-socket joints, 

 and lines the tendon grooves. 



In some places elastic fibers are found imbedded in hyaline car- 

 tilage -fibro-elastic cartilage. The elastic fibers send off at acute 

 angles finer or coarser threads which interlace to form a delicate or
