(Deiters.) connect the cells with one another, and also with distant parts of the animal body. The function of the fibres is that of conducting stimuli or impressions (represented by mole- cular or invisible movements) to and from the nerve-cells, while the function of the cells is that of originating those of the impressions which are conducted by the fibres outwards. Those of the impressions which are conducted by the fibres inwards, or towards the cells, are originated by stimuli afifecting the nerve-fibre in any port of its length; such stimuli may be contact with oth^ bodies or pressure arising therefrom (mechanical stimuli), sudden elevations of temperature (ther- mal stimuli), molecular changes in the nerve-substance pro-.
