抄録

The distribution of the neurons of origin of the internal ramus of the rabbit accessory nerve in the nudeus ambiguus was studied with injection of HRP into both the inferior vagal ganglion and the muscles of the palate and pharynx following the intracranial severings of the ipsilateral rootlets of the vagus and glossopharyngeal nerves and/or those of the cranial root of the accessory nerve. The neurons of origin were found to be located in the subnucleus DiG at the level of the caudal half of the nucleus ambiguus, with their number being about one-tenth of the total number of the constituent neurons of this nucleus. DiG is the abbreviation for a cell grouping formed by a diffuse arrangement of the largest neurons of the nucleus ambiguus, and which occupies the caudal two-thirds of the nucleus. The neurons of origin were intermingled with the vago-glossopharyngeal rootlet neurons at the rostral levels of the DiG. At the level of its most caudal one-third, however, that subnucleus was occupied only by the neurons of origin of the internal ramus.
