these results suggest that crf- and avt-like substances , present in nil fibres ( probably originating in the npo ) , may have an integrated role in the release of the cell products from the pars intermedia , and that the control of corticotrops in the rostral pars distalis , innervated exclusively by ir-crf fibres ( probably originating in the nlt ) , does not require a simultaneous presence of crf- and avt-like substances .
