Abstract

The central localization of the superior laryngeal nerve (SLN), recurrent laryngeal nerve (RLN) and pharyngeal nerve (PHAR) in the ferret (Mustela putorius furo) and mink (Mustela vision) was determined by neuronal tract tracing techniques. The anterograde transport of horseradish peroxidase (HRP)/wheat germ aggluttinin conjugated HRP mixtures (WGA-HRP) revealed afferent fibres of the SLN projecting ipsilaterally in the tractus solitarius (TS) before terminating in the ipsilateral nucleus of the tractus solitarius (nTS). In both mustelids large concentrations of terminal reaction product were observed in the dorsal/dorsolateral and medial subnuclei of the nTS; however, at levels near obex significant projections of the SLN to the interstitial subnucleus were also observed. Caudal to obex, sparse terminal labelling was identified bilaterally in the nucleus commissuralis (n com). There were no labelled afferent projections of the SLN to the spinal trigeminal complex in either mustelid; neither was afferent terminal reaction product detected in the medulla oblongata following labelling of the RLN (in either the ferret or the mink) or PHAR (in the ferret). Projection of the SLN to areas of the nTS associated with upper airway funct...Continue Reading
