up the spaces between, the bundles of fibres. The cells are generally 

 marked by one or more lines or stripes when viewed longitudinally. 



FIG. 61. Caudal tendon of young rat, showing the 

 arrangement, form, and structure of the tendon 

 cells. The bundles of white fibres between 

 which they lie have been rendered transparent 

 and indistinct by the applicationl of acetic 

 acid, x 300. (Klein.) 



FIG. 62. Transverse section of 

 tendon from a cross section of 

 the tail of a rabbit, showing 

 sheath, fibrous septa, and 

 branched tendon cells. The 

 spaces left white in the draw- 

 ing represent the tendinous 

 bundles in transverse section, 

 x 250. (Klein.) 



This appearance is really produced by the wing-like processes of the 

 cell, which project away from the chief part of the cell in different 

 directions. These processes not being in the same plane as the body 

 of the cell are out of focus, and give rise to these bright stripes when 

 the cells are looked at from above and are in focus. 



The branched character of the cells is seen in transverse section 

 in fig. 62. 



The cell spaces in which the cells lie are in arrangement like the

 (see fig. 63).
