A trial was made during this investigation to explore the nervous systems in some representatives of the main platyhelminthes groups, turbellarians, digeneans, monogeneans and cestodes. Mesostoma ehrenbergi and Udonella caligorum were selected as representative of turbellarians,in addition to Temnocephala fulva, Phyllodistomum folium and Gorgodera vitelliloba as digeneas, Khunia scombri as monogenean, and a cyclophyllid Hymenolepis diminuta and a tetraphyllid, Phyllobothrium pirieri, as cestodes, using enzymatic technique(acetylthiochole iodide for esterases). The nerves distribution, including both cerebral ganglia and their anterior connections and posterior nerve trunks, of each species, are given as revealed by this enzymatic technique.
