TABLE 63 — Condensed 

 Ratios of the length of the inner pillar cells — according to the turns of the cochlea 



TABLE 64 — Condensed 

 Ratios of the length of the outer pillar cells according to the turns of the cochlea 



TABLE 65 — Condensed 



Comparison of the average length of the inner and outer pillar-cells — -without 



head. 



pillar cells are smallest in man and in the rat and alike in the 

 other two forms, Retzius ('84). Hensen ('63) states that in the 

 base of the human cochlea both pillar cells are equally long. 

 Later, Pritchard (78) supported this observation. In the 

 literature, however, no one except these two authors report the 

 inner and outer pillar cells in the base of the adult cochlea as 

 equal in length, but the inner is always stated to be shorter than 

 the outer. We may therefore say that most authors agree that 

 the inner pillar cells are at earlier stages longer than the outer, 

 then they become equal, and finally the outer surpass the inner.
