Summary
The uterine cervix, urinary bladder and rectum of guinea pigs were injected with Fast Blue dye for retrograde transport studies. Dye-laden neuronal perikarya were detected for each viscus in the paracervical ganglion. These same perikarya also exhibited immunoreactivities for tyrosine hydroxylase, aromatic amino acid decarboxylase, dopamine β-hydroxylase, neuropeptide Y, or vasoactive intestinal peptide, though the perikarya projecting to the urinary bladder did not exhibit immunoreactivity for aromatic amino acid decarboxylase. The results of this study indicate that the guinea-pig paracervical ganglion projects to viscera in addition to the uterus, and that the ganglion contains a range of immunoreactivities related to adrenergic and non-adrenergic neurotransmitters.
