 lacunae a, medullary and fat-cells b ; B, tendon with fibrillse and cartilage-cells c.

rows of narrow spindle- 

 shaped cells, connected 

 by slender processes, at 

 others uniform fibres, 

 or isolated spindle- 

 shaped cells. These are 

 placed at regular di- 

 stances apart between 

 the bundles of areolar 

 tissue. 



When tendons are in 

 contact with bones, 

 they frequently contain 

 cartilage - cells, either 

 isolated, or arranged in 

 rows (fig. 405 c) ; these 

 sometimes undergo ossi- 

 fication. 



The aponeuroses, fas- 

 ciae and tendinous 

 sheaths consist of the 

 same elements, but in 

 various proportions and 

 differently arranged ac- 

 cording to their func- 

 tions ; sometimes the 

 areolar fibres being pre- 

 dominant, the structure 

 agreeing with that of ten- 

 don ; whilst at others the 

 elastic tissue is greatly 

 developed (fig. 406). 



Magnified 450 diameters. 

 Elastic fibres from the inner part of the fascia lata, human ; densely interwoven and forming an elastic membrane.
