## Abstract Associated with the abdominal muscle receptor organs of crayfish are accessory neurons that inhibit the activity of the stretch receptors. Cobalt infusion into their cut axons reveals four accessory somata associated with each hemiganglion in the abdomen of the crayfish __Cherax destruc
The stretch receptor cells (SRs) of the abdominal muscle receptor organs (MROs) of crayfish send large axons directly to the last abdominal ganglion. In Procambarus clarkii some unidentified motor neurons and interneurons receive direct SR input (Bastiani and Mulloney, '88a,b). We used an isolated,
Morphological and physiological data were used to establish which motor neurons innervate known wing elevator and depressor muscles. Nerves to identified muscles were backfilled to establish the neuropilar morphology of neurons innervating each muscle. Individual motor neurons were recorded intracel
