Plate 11 



Portion of the cytoplasm of a cell in the bulb of the hair follicle before 

 filaments of keratin have commenced to accumulate. The picture is 

 typical of a retaining cell. There are small numbers of mitochondria, 

 (m), small vesicles, V, not obviously organized as a definite Golgi 

 apparatus, and vast numbers of dense (RNP) particles P which are 

 apparently free in the cytoplasm and not associated with membranes 

 (Fig. 50, p. 112).
