The source of this reflex stimulus can only be lookedfor in the irritation of centripetal filaments coming fromthe seat of the trauma. It is difficult to know whetherthese centripetal fibres belong to the cerebro-spinal orsympathetic system, and the question is of little im-portance considering the close relations between thesetwo systems. On the other hand, the centrifugalpath of the reflex, as regards the vaso-motor andthermal phenomena, is certainly provided by thesympathetic. It
