Disorders of sensory function and autonomic regulation in the larynx might result in such abnormal sensations of the larynx. In this study, we observed substance P (SP)containing sensory nerve endings and noradrenergic autonomic nerves in the laryngeal mucosa of the dog by light microscopy. SP containing sensory nerve endings were observed in intra-epithelial free nerve endings and taste bud-like structures. The intraepithelial free nerve endings were most dense on the lower surface of the vocal cord mucosa. The taste bud-like structures were classified into two types; simple terminations and reticular terminations. Both sensory SP containing and autonomic noradrenergic nerve fibers were observed around arterioles and in laryngeal glands. Disorders of fine neural control may be related to abnormal sensations of the larynx.
