Summary
Localization of the afferent neurons from the canine recurrent laryngeal nerve in the nodose ganglia (NG) and jugular ganglia was studied using the horse-radish peroxidase technique. Labeled cells were detected in the ipsilateral NG and presented no distinct pattern of distribution, but rather were scattered throughout the ganglion. No labeled cells were found in the contralateral NG or bilateral jugular ganglia. The size of labeled cells varied from 15 μm to 60 μm. Two to six labeled cells larger than 45 μm were detected in each dog. Most of the labeled cells (62%) had a diameter between 30 μm and 5 μm. The percentage of labeled cells with a diameter between 15 μm and 30 μm was 30% and between 45μm and 60μm was 8%. This difference in size of labeled cells in the NG may be related to functional differences among the receptors mediated.
