Fig. 1. Plasma cell in loose connective tissue of the human epididymis with most 

 of the features present which usually are found in a mammalian cell: nucleus (N), 

 nucleohis (Ne), Golgi zone (G), mitochondria (M), ergastoplasm (E). The cell is 

 freely suspended in between the connective fibers and displays a number of surface 

 extensions (S). Magnification 10,500X
