Summary
Following horseradish peroxidase (HRP) application into each of the superior laryngeal
nerve (SLN), internal branch (Int) and external branch (Ext) of the SLN, the inferior
laryngeal nerve (ILN), and the anterior branch (Ant) of the ILN, all labeled sensory
neurons were found in the nodose ganglion (NG) of cats ipsilaterally. Labeled neurons
of the SLN were seen in the rostral part of the NG. Within the rostral part of the
ganglion, sensory neurons of the Int-SLN were aggregated and occupied the most rostral
part while those of the Ext-SLN were scattered and in the middle part. Cell bodies
of the ILN were slightly compact and located in the rostral part of the NG, extending
to the middle part. Within the rostral and middle part of the NG, labeled neurons
of the Ant-ILN were sparse and occupied in the middle part. Laryngeal sensory cell
bodies were unipolar neurons of medium size. The mean number of labeled neurons of
the SLN was 336 whereas that of the ILN was 124.
