Sensory nerve endings in the mucosa of the epiglottis--morphologic investigations with silver impregnation, immunohistochemistry, and electron microscopy

, : Sensory nerve endings in the mucosa of the epiglottis--morphologic investigations with silver impregnation, immunohistochemistry, and electron microscopy. Otolaryngology--Head and Neck Surgery 96(1): 55-62

This study was conducted in order to investigate the structure of sensory nerve endings of the human epiglottis and substance P immunoreactive nerve fibers of the canine epiglottis in relationship to physiologic functions of the larynx. The human epiglottis was observed by light microscopy (silver impregnation) and electron microscopy, and the canine epiglottis was studied by peroxidase-anti-peroxidase (PAP) immunohistochemistry. The results are summarized as follows: (1) In the membranes of the epiglottis, we observed free endings of simple or complex tree shape, corpuscle endings with glomerular patterns, and taste-bud-like structures, and (2) electron microscopic studies revealed varicosity of the terminal axon with processes that contained small, clear and large, dense cored vesicles. Substance P was observed in these structures, and it was suggested that substance P was related to perception in the larynx.
