Sensation of thirst in normal and laryngectomized man

The purpose of this study was to evaluate the role of the larynx in sensation of thirst and to identify precise areas responsible for the sensation in normal and laryngectomized groups. The present analysis showed that the laryngectomized group was less aware of the sensation and less able to localize it than the normal group. Both groups localized the sensation from the base of the tongue to the larynx as well as in the pharynx.
