Abstract:
The primary sensory neuron simultaneously innervating two or three viscera was studied in this paper, In one group the viscera in neck, thorax, abdomen and pelvis of the rat were paired off, i.e. esophagus-thyroid gland; esophagus-trachea; heartstomach; lung-stomach; left kidney-spleen; urinary bladder-uterus; urinary bladderrectum; uterus-rectum. Propedium iodide (PI) or fast blue (FB) and bisbenzimide (Bb) or nuclear yellow (NY)were injected separately into the first and second organ of paired viscera.PI-Bb (or FB-NY) double labelled cells were observed in corresponding ganglia (dorsal root ganglia and upper and lower ganglia of vagus nerve). In another group, PI, FB and NY were injected into urinary bladder, rectum and uterus separately. We observed a very few of PI-FB-NY triple labelled cells in L_(1-2) dorsal root ganglia.The above findings indicated that there are sensory convergences of visceroviscera in the same sensory ganglion cell in rat.
