The various longitudinal trunks are connectedby commissures which at stated intervals pass aroundthe proglottis; they also give off branches by whichthe various organs are innervated. Near the lateral nerve trunks are located the mainlongitudinal canals {lex) of the excretory system whichoriginate in an irregular network in the head andfrom which are given off numerous branches oftenin the form of a network of fine vessels in each pro-glottis.
