Nuclear inclusions in the nerve cells of the sphenopalatine ganglion of the dog.

Large numbers of nuclear inclusions have been found in the nerve cells of the sphenopalatine ganglia of six healthy adult dogs. Their morphological characteristics are similar to those previously described elsewhere. The presence of simple and granular bodies in normal cells seems to support the hypothesis that these nuclear structures might be considered as normal nuclear organelles related to cellular metabolic activity.
